Very cool. I am now wondering if the 'grub worms' I thought my hen was so happy to munch on were some sort of caterpillar...big fat green things, I forget their markings, mostly she was finding them at the foot of a Ribes sanguineum. Is there a web site that shows what plants host what? I know next to nothing about what butterflies/moths even live in my neighborhood. Yet another gardening thing to learn I guess.
