An overly-cooperative model?


I found this beautiful gravid female Phidippus johnsoni hanging motionless, upside-down from a grass stem this morning. She had all the hallmarks of envenomation by a spider wasp (Pompilidae). She was unresponsive, had extremely limited movement upon prodding, and was basically dead to the world.  Being such a large animal, it is possible the wasp was unable to drag the spider to her burrow, or perhaps I interrupted while the female wasp was scouting the terrain ahead.  Anyway, I took some photos with this suddenly very easy to work with subject, and then returned her to her stem of grass. Perhaps the wasp will retrieve it, and if not it will make a good meal for someone!

You can see in this shot, there is something not quite right about how she is holding her legs…

This shows how big the jumper was!
