A Hidden Predator

(I started this blog early in September when my blog site wouldn’t let me insert pictures. I couldn’t wait until next fall to post it.)

Any butterfly in an awkward position usually indicates a predator.

In the case of this spicebush swallowtail, it was a female crab spider. (Females are much larger than males.)

The butterfly was still alive and could only move its head and legs a little.

Crab spiders ambush their prey. They inject it with venom to immobilize it and then suck it dry.

The body of the swallowtail lay on the ground the next morning. Three days later a sliver-spotted skipper “hung” from the same phlox plant.

  3. I little gruesome, but that is the way that things happen in nature. I doubt that I would have spotted the hidden spider. Nice photos and narrative.
