Figuring out the A720….

CRW_2909

I am continuing to tinker with the Canon A720IS for wide angle macro, as it seems this will be the only machine I have for the purpose for he forseeable future….I now have a method of holding the camera and the slave flash, but would like to do some more tinkering before I lay it all out. Today I was up at Mt. Tolmie again, where I waited in vain for a glorious dawn…But I did see a spectacular moonset!

Click the image below for a larger version.

The subjects of my macro experiments were snakeflies and some Nomada cuckoo bees. These relatively inactive subjects proved ideal for my tinkering, and I managed a good many angles for each. If you have any thoughts on these compositions, please let me know….I was constrained a bit by ambient light, as it was near dawn, but in the future I want to let the landscape show through more.

CRW_2731

Snakefly on dead camas. I kept the sky dark here, which is kind of a fashion cliche from a few years back, but I like the brooding atmosphere

CRW_2754

This is kind of full ventral, but the light is not “believable”…

CRW_2724

This is kind of cool, as the insect is descending…I do say that I “chose” these compositions, but with the shutter lag of the ancient compact, I get what I get!

CRW_2824

This shot of a Nomada is pretty straightforward. I kept the sky and tree dark to keep the brooding atmosphere.

CRW_2855

Here I have tried to get some background vegetation other than trees, but the grass actually resembles a tree!

CRW_2859

This is a peeekaboo shot of the cute face of the bee.

CRW_2877

The one shot I got that worked out of the cloud-obscured sun with the bee. I really like this one, even with the spittlebug below

CRW_2863

Another view of the Nomada while sleeping.

OK, now for some comparisons, here are some shots of the same subjects with the 100 mm macro on the DSLR

IMG_2894

Not as much interest in this background.

IMG_2964

What I like about the 100 is how I can maneuver everything precisely o get a clean composition…That being said, maybe it is a bit stale.

IMG_2990

This shows the stiffness of the sleeping bee’s posture

And in other news, check out this beautiful bee fly I found!

IMG_2955

The tip of the abdomen is orange at certain angles

IMG_2951

A cool fly from any point of view

And a bit wider to show more of the perch

 

 

 

Experimentation with sleeping bees and wasps

CRW_2600

This morning Catherine and I tried something different with our spider observations: instead of going out at night, we would get to the beach before dawn, to catch the tail end of spider activity. Turns out, as soon as any light is in the sky, the widows are out of sight, presumably to avoid dawn-foraging birds. So that meant I had a bit of time for some photography!

I really wanted to try out the small Canon A720IS I had used on the alligator lizards in the context of capturing wide angle closeups of sleeping bees at dawn. I did manage some shots of Ammophila wasps and Coelioxys bees, but I am not entirely sure I am pleased with them. Perhaps the strength of the camera lies in wide angle macro in better lighting conditions. Anyway, it made for some neat images, which I share below.

CRW_2568

Ammophila, all lit up by a surprisingly well-behaved slave flash, the beach habitat stretched out behind.

CRW_2617

An in-your-face view of Coelioxys, with a bit of colour in the sky.

CRW_2575

Coelioxys with a bit more of the trees toward the beach showing.

Now we move onto dawn shots of the same subjects shot with the DSLR and 100 mm macro. We also found some cuckoo wasps!

IMG_1798

Sleeping cuckoo wasp! I wish I had brought my diopter for better magnification!

IMG_1863

IMG_1919

This little cuckoo is waking up.

IMG_1932

It stirred around for a few moments, then went dormant again.

A couple of Sunday outings

IMG_1197As I mentioned in my last post. Catherine and I are working late nights observing black widow behaviour, so I do not really get the opportunity to go out at dawn as much as I normally like to. We have begun to take Friday and Saturday nights off, however, so assuming I can get my sleep schedule quickly reorganized, dawn shoots are possible!

This morning, I went out to Mt. Tolmie, in the hopes of seeing a spectacular dawn. Unfortunately, the light and colour were a bit subdued, but I did manage to get some snakefly photos with some colour in the sky.

IMG_1164

Imagine this, but with a blazing orange sky, and some direct sun peeking through the wings….Someday!

IMG_1237

I also found a fat male snakefly!

Snakeflies were about all that was on offer at Mt. Tolmie, so after breakfast I headed down to Dallas Road, on the shore near Beacon Hill Park. I knew of an Anthophora bomboides colony, and hoped to get some pics of them waking up.

IMG_1357

Anthophora bomboides makes these little turreted nest holes in the eroded banks above the sea.

IMG_1354

On a steeper slope, the nest shave no turrets, presumably because incoming rain and debris are not a problem. I found a few bees poking their heads out, but none sunning or getting ready to fly until…

IMG_1333

Right in front of me, a male grabbed and attempted to copulate with this female. I didn’t get the male in the shot, but here is the female looking stunned on the ground.

IMG_1338

The female is recovering from her whirlwind romance.

IMG_1347

You can see where hey get the specific name “bomboides“, as they look very similar to local bumblebees.

IMG_1417

Picking my way along the shore, I came upon my first sleeping Coelioxys of the season!

IMG_1384

These sleeping bees make fine subjects, as it takes them a long time to warm up.

IMG_1419

Above the cliffs, in the Garry Oak meadow, I found this bristly tachinid fly.

IMG_1428

I also found one of my favourite elaterids, Selatosomus edwardsi.

IMG_1434

These beautiful click beetles are large and robust.

IMG_1442

In a snowberry bush I found this beautiful and delicately coloured Araniella displicata.

IMG_1460

And to cap off a very productive morning, I ran into one of my favourite running crab spiders of all time, Tibellus oblongus!

 

A very spidrous summer planned

IMG_7051So this is where I find myself: I am currently employed as a field assistant to my partner Catherine Scott, as she spends the spring and summer of 2016 doing thesis research on Vancouver Island. Over the winter and early spring, I had several interviews for postdoc positions, but ultimately did not get any offers. I am still in the market, as this field gig is not paying much, but this is where my employment situation stands.

Dang, that’s a long trip!

The fieldwork may not pay much, but it sure has been exciting. The first stage of the work involved a ridiculously long roadtrip from Toronto to Texas, and out to LA, up the coast and across the Strait of Juan de Fuca to Victoria. Our objective in this was threefold: 1) we had to collect some  beautiful “Texas widows”, a variety of  western black widow (Latrodectus hesperus) for later lab research, and 2) we had to attend a wedding in Los Angeles and 3) we needed to get our vehicle to BC for the fieldwork.

Of course, this roadtrip was a great opportunity to get some cool shots of the natural world along the way. In the following shots, you will get a taste of what we encountered.

IMG_2211

Catherine taking notes on spiders we collected.

IMG_3273

Joseph Lapp, an arachnologist in Austin graciously took us out for some spidering and lunch near the UT Austin field station. We met up with many great people along the way, including Bekka Brodie and Viorel Popescu in Athens OH (former labmates), Alex Wild in Austin, Terry McGlynn in Pasadena, Christy Pitto in southern Oregon, and Thomas Shahan and Kathleen Neeley in northern Oregon, who spent the day with us shooting photos and wandering the canyons. I apologize for not taking more people pictures!

IMG_3416

Catherine collects a Texas widow in the boonies of southern Texas.

IMG_6964

Here is what the Texas widows look like: the adult females retain the juvenile colour pattern, with flamboyant reds and yellows on the dorsal surface of the abdomen. The extent of this red varies, but this is pretty typical.

IMG_3485

Southern Texas is awesome for birds. We saw a great many Crested Caracaras, which was a big highlight of the trip. I last saw these birds in Guyana.

IMG_3781

We got to see 3 species of recluse spider. This one is the Big Bend recluse, found about 100 km east of the Pecos River valley.

IMG_3570

Another highlight was finding Scytodes spitting spiders. We saw both Scytodes thoracica as well as this unknown (to us) species from southern Texas.

IMG_3607

In the Seminole Canyon, we found the only Aphonopelma tarantula we saw on the trip.

IMG_3716

It was extremely frustrating to have to burn through Arizona and New Mexico to get to the wedding, as there is absolutely stunning mountains and countryside to explore. Here we are passing by a wonderful region…

IMG_4654

After the wedding in LA, we got some opportunity to change the oil, hang out with Terry McGlynn and see some hawks at Palos Verdes.

IMG_5109

The beautiful Diaea livens, a green crab spider found on oaks in California.

IMG_5368

In Monterey, we met up with the invasive Badumna longinqua, a desid spider that makes messy cribellate capture webs very close to the ocean.

IMG_5396

While searching for Badumna near the docks in Monterey, we came upon this sea lion chilling out. They are really quite tame in the harbours!

IMG_5747

Out for the day with Christy Pitto, at the headwaters of the Rogue River in southern Oregon, we found this beautiful Tibellus, and I found a new angle to shoot it from.

IMG_5954

Our coolest spider find was with Christy Pitto, a gorgeous Mecicobothriid from near her cabin.

Cheapskate Tuesday 29: Alligator Lizards with the A720 IS

IMG_2450-2

For this image, I wanted to show the Garry Oak habitat that I found this beautiful Northern Alligator Lizard in, as well as the gorgeous detail of its long body.

One of the greatest trends in wildlife and macro photography is so-called “wide angle macro”, or getting close to a subject with a wide lens in order to show both detail of the subject, and some of the surroundings for context. In addition, the exaggerated field of view places the subject right in your face in a way that standard macrophotography struggles with.

To achieve this with a DSLR, there are a number of lenses that can be used, including some very exotic optics such as the Venus 15 mm Macro (see Thomas Shahan’s video here for a good intro).

Well, here at Cheapskate Tuesday, we can’t afford that kinda thing (yet), so we have to make do. One way to acheive this type of look is both cheap and abundant: old compact cameras! I happen to have a fine Canon A720 IS that I bought some years back for 35 bucks at a pawnshop in Victoria. It focuses extremely close, and from my days shooting the S2IS and S5IS, I knew it could be hacked with CHDK in order to get RAW file capture for improved dynamic range and white balance editing.

IMG_7251

The A720 in all its glory. Truly a fine 8 MP compact!

IMG_7247

This CHDK menu shows some of the great tweaks that are available (in addition to RAW capture). The overrides of both ISO and aperture are very useful, and really work!

Well, working with a compact still has some disadvantages in terms of the maximal quality of the images captured, as well as the limited resolution available…The compact is versatile though, and is very light. One very cool feature of this model is that it has a global shutter and a very high flash sync speed, so flash-illuminated shots can still retain great detail in a bright sky.

The most important thing is that it focuses VERY close even at the widest zoom setting, allowing for the shots of the lizard you will see. There is a set of crazy tricks I used when shooting this image that I won’t detail here, but will cover in a future Cheapskate Tuesday post…Suffice it to say, if you desire the ability to make images like this on the cheap, and don’t mind a bit of tinkering, pick up a similar camera today, if you can find one at a good price….

IMG_2446

This shot shows great detail of the lizard’s head, as well as the rock outcrop and blooming camas in the background.

IMG_2455

Another shot of the lizard posed on a piece of broken wood. Again, note the detail visible both in the lizard as well as the background.

IMG_2465

Head on view!

IMG_2466

Probably one of my favorite shots from this session, just the face and feet are shown in detail, while both the Garry Oak and camas are visible in the background. So cool!

IMG_0191

BTW, this camera can also be used for shots like this one, showing Catherine seeming to be dwarfed by a dock spider…

 

 

Hawks at Palos Verdes

IMG_4662Catherine and I are out in California right now, in the midst of a cross-continental journey we are calling #SpiderTrip2016. This trip has taken us down the east-central part of the country to Austin and further south, where we collected some very colourful black widows  for Catherine’s research.

IMG_3501

Catherine examines a guard rail in southern Texas, where we found black widows in abundance.

 

Right now we are in L.A., where we have been for several days to attend a wedding in Redondo Beach. As the wedding was Sunday night, on Monday morning we went out to find a park to have a picnic and see what we could see. We ended up on the cliffs of the Palos Verdes Peninsula, a region of L.A. that neither of us have visited. This peninsula has some soaring cliffs and beautiful views of the ocean, as well as a great interpretive centre at Point Vicente focused on natural history.

 

As we were eating lunch, the screams of a rapidly diving Peregrine Falcon alerted us to check out the cliffside. While I tried in vain to get a shot of a diving falcon, we clued in to the fact that the falcon was harassing a pair of Red-tailed Hawks nesting on the cliff ledge below.

IMG_4609

This was the best I could manage of these amazingly quick falcons…I did see several dives against the flying hawks, which they countered by rolling and presenting their talons to the approaching falcon. This is not just idle harassment on the part of the falcon either, as they are known to kill hawks during these high-speed attacks. 

IMG_4693

A Red-tailed Hawk, presumably incubating eggs on the cliffside of Point Vicente.

These hawks are well known to the local birders and photographers, and it isn’t hard to see why. Their activities are well in view from the top of the cliffs, and they come very close to the walking path as they provision their nest and ride the updrafts from the ocean winds striking the cliff face.

Anyway, here is a selection of photos I managed to get during a couple hours of watching this incredible specatacle:

IMG_4654

This was the incredible first flyby I managed to shoot of the female Red-tailed Hawk looking right at me as she flew by.

IMG_4665

The contrast of the red tail and the blue sea behind is really quite striking

IMG_4703

Some local birders told me this individual with the broken tail feathers is the male, and it makes sense, as the incubating hawk had an intact tail.

IMG_4753

We saw one of the hawks grab some vegetation from the crown of this palm several times. They would also retrieve sticks from a shrubby slope beneath the cliff.

IMG_4779

The female heads back to the nest with a stick.

IMG_4762

I didn’t know it at the time, but I suspect this dramatic dive was the beginning of a successful rabbit hunt on the shrubby slope. I did not see the kill get made, as it occurred below the cliff.

IMG_4811

One of the pair is engaged in tearing the fur off of the rabbit that they killed. 

IMG_4650

The views of these hawks just cannot be beat, and with falcons, seals, pelicans and more thrown into the mix, you could do a lot worse than to spend some time at Point Vicente! If you are in the L.A. area, I highly recommend it!

 

Gray-fronted Dove

 

5982995126_7103d35075_b

 

This post is gonna be short; Catherine and I a prepping for a very long roadtrip to Texas, LA, and eventually to BC to start Catherine’s field season. This is just a video of a Grey-fronted Dove (Leptotila rufaxilla) feeding nestlings at the Nouragues Station in French Guiana.

This nest was right beside the showers in camp, and to get this footage, I set up my camera and started recording, leaving it there until the card filled or the battery ran out. This was a labour intensive process, as the majority of clips recorded were just the bird sitting there and the chicks sleeping.

I think that this clip of feeding made it all worthwhile though, as it gives a rare view of how the chicks “plug in” to the adult to receive their meal of “crop milk

Weekend Expedition 71: Mississauga salamander hunt

IMG_2509


After a week of warmth, Gil Wizen and I set out for the same woods we visited last week, in order to see if we could find any salamanders out to take advantage of the vernal pools. The snow was completely gone, and the pools ice-free, although it was overcast and a nippy 5 C.

IMG_2468

There were flies and moths out on the vegetation, indicating at least that the insects have begun to wake up.

IMG_2470

Even a male orb weaver was out, although he did not have a capture web.

IMG_2474

Near the vernal pools, we started to flip some logs, hoping for a treasure rove of salamanders, but initially we found only millipedes, beetles and some small red-backed salamanders.

IMG_2517

There were quite a few firefly larvae in the rotted wood, as well as some rove beetles.

IMG_2482

Very close to the vernal pools, Gil found this Jefferson’s Salamander, Ambystoma jeffersonianum. This (to me) was a big beast, dwarfing the longtoed salamanders from BC. This species is endangered in Ontario, although it is common in other parts of its range.

IMG_2491

They are a difficukt species to capture well in a photograph, and for this shot I stood off at a distance and used the 300 mm. Luckily it was overcast, and the light in the forest was diffuse. The salamander was quite motionless, and probably was not pleased about being out in daylight.

IMG_2501

We replaced the big amphibian, and wished it well. Soon, hopefully, many of its fellows will come down to breed in these little vernal pools.

IMG_2506

We also found a few redbacked salamanders, which are a species of plethodontid. These animals have no need of open water to breed, and in fact lay their eggs in moist soil and wood, hatching out into juveniles with legs already formed. They are lungless, and never need gills either!

IMG_2515

These Plethodon are a bit easier to photograph, although they might have benefited from a more diffuse flash.

IMG_2533

After leaving Gil to pack for his coming trip to Ecuador, I found my way home was blocked by a big St. Patrick’s day parade. It was scheduled to last several hours, so I crawled through the awful Toronto traffic to Tommy Thompson Park to kill some time until my annoying relatives had cleared out of town. I found a couple of nice sac spiders under some bark.

IMG_2530

These Clubiona have very impressive chelicerae, but never seem to threaten to use them. Instead, they are very prone to jumping when disturbed.

IMG_2553

I found some European fire ants under a rock, and took some photos. They were still rather lethargic, and hence not much of a stinging hazard!

IMG_2560

They are quite pretty little ants, and Toronto seems to abound with them now.

IMG_2596

Here a worker antennates a queen. You can see her much-enlarged thorax and wing scars.

IMG_2618

Despite their wings, the queens do not disperse by flying in North America, a trait they seem to have lost. In addition, the colonies here are often much larger than those in Europe.

 

Weekend Expedition 70: Mississauga/Credit River

IMG_2191

On Sunday, Catherine and I went out to Mississauga, where we met up with Gil Wizen, one of my favourite macrophotographers to go out for a early spring hike around the woods above the Credit River. It was such a treat to be out with a fellow invertebrate zoologist, not having to explain why exactly we should flip over a given log, or pull up a piece of loose bark…How very rarely do we get to go out in the woods with another person with the same agenda!

The forest was snowy, but warming, and we are anticipating a major thaw through the week….Very soon, the famed Ontario salamander fauna will be on the move to vernal pools for breeding. This weekend we did not find any salamanders, but we did find a great variety of cool arthropods, thanks in no small part to diligent searching by Gil.

IMG_2152

The wooded bluffs above the Credit River, near the Mississauga campus of U of T was where we wandered. The geology of this place looks pretty fascinating, with some thin layers of sandstone very near the surface, often pushed upward by tree roots.

IMG_2151

Catherine and Gil on the way to the forest.

IMG_2155

The mixed forest seemed to have abundant birdlife, and it would be good to come by earlier or later in the day to see if we could find some owls…

IMG_2171

Many of the birds were doing what we were doing, probing under bark and looking in crevices for invertebrates.

IMG_2183

One of our very first finds was also one of the coolest: A Dolomedes tenebrosus, looking fat and happy under some loose bark. This is a species in the fishing spider/nursery web spider family (Pisauridae), and it is usually found near water. They are undoubtedly major beneficiaries of abundant aquatic insect hatches in certain seasons.

IMG_2260

Here is the same spider resting on a block of the sandstone cap that we found thrust up near the tree roots. The large eyes of these pisaurids are evident, and hint at relationships with wolf spiders, also in the Lycosoidea clade.

IMG_2270

We found a much smaller Dolomedes tenebrosus nearby under some leaves. Interestingly, both of these spiders seemed not strongly affected by the cold, and were able to move about even though it was hovering near zero.

IMG_2199

Gil examines a rotted and fallen trunk. I asked him whether he had done this sort of think since childhood, and it seems that like me he has always flipped logs and rocks looking for invertebrates. A born naturalist!

IMG_2226

A caterpillar of Idia lubricalis (a hermiine erebid), also found under leaves. Thanks to Gil for the ID!

IMG_2211

Like the previous week in Crother’s Woods, we also found a number of crab spiders and running crab spiders. Here is a running crab, likely a Philodromus species.

IMG_2231

A small (Handsome Fungus, family Endomychidae) beetle found in fungus-rotted wood. This one has a very pleasingly-shaped pronotum and daintily-clubbed antennae.

IMG_2290

Gil also uncovered some tiny psuedoscorpions, which was a treat to see.

IMG_2237

Many thanks to Gil, for leading us to a very productive patch of woods. We look forward to getting out again soon!

 

 

Weekend Expedition 69: A muddy slog in Crother’s Woods

IMG_1777

Sunday afternoon was warm and sunny, but when Catherine and I went out to Crother’s Woods, the forest was sodden and mucky. Nonetheless, we set out for a short stroll, looking under bark of fallen trees and in the leaf litter for creatures…

So have a gander at what we found!

IMG_1732

We found a bunch of Bassaniana (now Coriarachne) bark crab spiders overwintering in bark crevices. These are extremely cryptic on bark, and are probably very abundant all up a tree.

IMG_1843

These bark crab spiders have very robust forelegs, and likely can take relatively large prey.

These bark crab spiders are extremely flat!

These bark crab spiders are extremely flat!

IMG_1753

This running crab spider (Philodromidae) was also found under bark, along with the Coriarachne.

IMG_1743

Yet another philodromid. I wish we knew the species here!

IMG_1828

Catherine managed to find a sac spider (Clubionidae, likely genus Clubiona) in a sac, also under bark.

This shot shows the sac spider's eye arrangement.

This shot shows the sac spider’s eye arrangement.

IMG_1804

Catherine found this eastern yellowjacket queen under some bark as well. She is overwintering, and we took good care to replace her in an equivalent crevice.

IMG_1817

She was completely motionless, with wings held in a protective posture typical of overwintering yellowjackets. I was interested to see that her wings tuck under the spines on the hind tibiae.

IMG_1857

One of our coolest finds was this minute tree-fungus beetle on a bracket fungus on a birch tree. (family Ciidae,  maybe Ceracis thoracicornis? OK, this is not even a ciid at all! Gil Wizen has informed me this is a tenebrionid, Neomida bicornis!) 

IMG_1858

These beetles tunnel through the tough fungus, and I cannot understand how these forward-facing pronotal spines are helping!

IMG_1861

This beetle was less than 2 mm long, and made my day.

IMG_1887

If anyone out there knows what they use these spines for, please let us know!

IMG_1784

This looks like the larva of a flat bark beetle (Cucujidae) (but wait! It is not! Again, Gil Wizen to the rescue! This is a fire-colored beetle, Neophryochroa femoralis

mag view

A closer crop reveals that the water droplets act as magnifiers, bringing into view structures such as the tracheae, visible through the translucent cuticle (click picture for larger view).

IMG_1785

Like most of the under-bark fauna, these beetles are very flat! Even adult cucujids are very dorso-ventrally flattened.

IMG_1771

Although much of what we saw was above freezing, wood in contact with the soil was still partially frozen, and these isopods were in the midst of ice. Ice-o-pods. Get it? Anyway, we are due for more freezing weather in Toronto, so I hope you have enjoyed these pics…It is not likely we will get any more this week!
