Trashy Lady

We have a female Trashline Orbweaver (Cyclosa turbinata) living in one of our blueberry bushes. She's constructed a lovely vertical line of "trash," in the middle of which she sits and waits for prey. Her markings allow her to blend in quite well. She doesn't like it when I peer at her (she bunches her legs up in a defensive posture), but I managed to snap some shots anyway.

A distinguishing feature of this species is the two anterior dorsal humps on the abdomen, which are sometimes indistinct but always present. The abdomen tapers to a bulbous point (like a cartoon bump on the head). Some species are called "Lobed Spiders."

Look closely at the trashline. Yes, there are clumps of silk. But among those...the bodies of her victims.

You can see one of the abdominal humps clearly here.
