Weekend Expedition 72: Leslie Spit with Gil and Catherine

20161023-img_4179

Fall is swiftly turning into winter here in southern Ontario, with cold nights and disappearing leaves…This weekend looked like the last in while to offer any kind of warmish temperatures, so Catherine, Gil Wizen and I headed to Tommy Thompson Park (Leslie Spit) o see if we could find some cool arthropods. The following is a condensed collection of pictures I managed to get.

20161023-img_3656

On the way to pick up Gil at the train station, I snapped this shot. It actually has Catherine in the frame.

20161023-img_4161

You can see that the goldenrod has largely gone to seed.

20161023-img_3705

A surprisingly colorful Phidippus audax.

20161023-img_3718

Just look at that abdomen!

 

20161023-img_3670

There were quite a few syrphids about, some of them just had to bask on exposed perches in order to warm up enough to fly.

20161023-img_3767

We saw about a jillion cucumber leaf beetles (Diabrotica undecimpunctata), mainly feeding on goldenrod

20161023-img_3747

A “buffalo treehopper” (a membracid in the genus Ceresa) hides out on a willow stem. Gil took a bunch of shots of this with both wide lens and MPE-65, so look out for them!

20161023-img_3721

This is an alydid bug (broad-headed bug), one of several we saw basking in the morning sun. This is likely Alydus eurinus, a common species in Ontario.

20161023-img_3855

These beachside wolf spiders (Pardosa) are plainly ornamented, but just a lovely shade of bluish gray.

20161023-img_3836

A really really big mite we found under some bark. This is likely a species of Trombidium.

20161023-img_4191

The subjects of a high-mag MPE-65 shot have got to be really calm creatures. Check out how this pierid is dwarfed by Gil’s diffuser.

20161023-img_4190

It was the most cooperative pierid ever.

 

20161023-img_4197

This is my attempt at wide-angle macro of the same insect.

img_3863b

A squashed Pardosa wolf spider on the road, being fed on by Myrmica rubra.

20161023-img_3874

Winter is definitely coming. This Culex pipiens has a “hypertrophied fat body” (she is fat) a condition that adapts her to living out the winter in a sheltered location.

20161023-img_4076

Golden dung flies (Scathophaga stercoraria) having an end-of-summer romance.

20161023-img_4002

A Myrmica rubra worker investigating a fungus-killed caterpillar. If she feeds on this carcass, and gets infected, her colony will likely kill her, then dispose of her body somewhere far away.

20161023-img_4113

The alianthus webworm moth (Atteva aurea) is a beautiful species that is not found in BC…Though seems quite common here.

20161023-img_3879

A gorgeous amaurobiid spider, recently disturbed from her cribellate silk retreat.

 

20161023-img_4141

A running crab spider in the genus Thanatus. They look much the same wherever you find them.

20161023-img_3899

OK, I saved one of my fave shots for last, this time it is an Agapostemon bee sitting in a flower. I just love the colour combinations and the textures.

A roundup of recent shots

IMG_4428

The spider fieldwork Catherine and I have been doing at Island View Beach progresses slowly. Natural history observations and experiments take up most of our nights, but I have still been getting the opportunity to do some photography and arthropod outings here and there. Here is a sampling of some recent shots that I think you might enjoy.

IMG_3281

This is Island View Beach, near our fieldwork site. It is a gorgeous beach, and a rare habitat type: dune vegetation is in short supply around here.

IMG_3287

One of the rare plants to be found on Island View Beach is the yellow sand verbena, a gorgeous dune plant with lovely-smelling flowers.

IMG_4486

This moth, the sand verbena moth (Copablepharon fuscum) depends on the yellow sand verbena, and is endangered. Catherine is working on a blog post about the controversy surrounding this species.

IMG_4710

On a recent outing to the beach in the daytime, I was very excited to find this robber fly, which I believe is Laphria franciscana. Wonderful blue eyes!

I have still had my eye out for spiders, and this Misumena vatia with a honeybee was a lovely find in Uplands Park.

IMG_3242

I have been finding some bee flies lately resting on grasses. Here is one I shot with the A720IS.

IMG_4834

Nighttime fieldwork on Cordova Spit allowed me to shoot this Ammophila against the darkening sky.

IMG_4862

The next morning, I found this purplish copper resting on a dead flower.

IMG_4897

I also found a beautiful potter wasp, an insect I do not often see resting on vegetation.

IMG_4453

During nightwork on the beach, I found this mother woodlouse with a load of babies.

IMG_4536

This sleeping aggregation of Coelioxys and Ammophila was particularly impressive. I wish I had been able to shoot hem at dawn!

IMG_5078

Early this morning at Mt. Tolmie, I found this beautiful little cuckoo wasp sleeping on some grass.

IMG_5107

A stinkbug against the dawn sky.

IMG_5138

This lovely cuckoo bee is either an Epeolus or Triepeolus…I found three of them at Mt. Tolmie this morning.

 

Coelioxys cluster

IMG_3073

Last night, Catherine and I were out again all night, performing what was ultimately a futile spider experiment on Cordova Spit (TIXEN in the SENĆOŦEN language). The one thing that did go right was that the dawn had some decent light, so I set out early to try to get some photos of sleeping hymenopterans.

I did not end up shooting very many, as I found this absolutely lovely cluster of Coelioxys which were just begging to be shot. These parasitic megachilids are wonderful subjects, and seem to sleep in small aggregations, sometimes with Ammophila wasps.  Their preferred perches are the dried seedheads of the Puget Sound Gumweed (Grindelia integrifolia), a fragrant seaside plant that is a good place to find halictids in the daytime.

Anyway, here are some of the pictures I took this morning!

IMG_3533

Shot with the 100 mm macro, this shot shows the mixed cloud of dawn, and the dew collected on the bees

The same bees shot with the A720IS, in the wideangle macro style.

The same bees shot with the A720IS, in the wideangle macro style. This gives the bees more of a bugeyed look!

IMG_3468

A lone Ammophila shot with the 100 mm. These wasps are so elegant!

IMG_3097

A similar view of the Ammophila with the A720IS. With this wide a shot you can really see the extent of the sky

IMG_3110

I turned around with the A720 to show the vegetation of the spit to the north

IMG_3528

As usual, when I find a great subject, I try to frame some up in portrait orientation, just in case I get the call for a National Geographic cover!

 

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.

moonset pano

 

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

IMG_2942

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

Another chrysidid on some dead grass.

IMG_1919

This little cuckoo is waking up.

IMG_1932

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

IMG_1983

IMG_1891

Head-on view of Coelioxys. Note the clamped mandibles.

IMG_1942

IMG_1968

A tower of Ammophila

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

In Laguna Seca, near Monterey CA

IMG_5332

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_5442

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.

We will shift to a largely nocturnal schedule to match the widows. Here Catherine observes courtship on the beach.

 

 

 

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
