What is that in the backyard?

I never saw anything like this in Brooklyn. Well, maybe one of those silly hats the kids like to knit. When I found this thing on my tomato plant I didn't know what to make of it. So, I consulted my super smart, conservationist, artist pal, Christopher (you can check him out at Hungry Hyena, in my links). He informed me that the fringe was actually Braconid parasites, injected into the Tomato Horn Worm (Caterpillar) by a wasp. COOL!
