Just now I visited Wind Walker’s blog and found that she has posted something about two lovely caterpillars of swallowtails that she is feeding. This remind of me of my caterpillars. I have found a lot of caterpillars of Papilio machaon, a similar species with Wind Walker’s, on carrot leaves. I tried to feed them but most of them died or escaped from the box. Only one transformed into a cocoon. Here are some photos.
When I first found this charming creature it was crawling on the ground so I didn’t know what its host plant is. I took a cabbage leaf nearby for granted. But the worm refused to eat.
