Cute mystery caterpillar
After reviewing your site, I think this might be either a swallowtail or a sphinx moth caterpillar, but I’m not sure. I found it on a lime tree in my yard. The white on its underside is coloration, not parasitic eggs. I went back outside to double check after looking at the picture. Speaking of the picture, sorry it isn’t great-I couldn’t get my camera to focus on the bug instead of its surroundings. I live on the windward (eastern) side of Oahu, in Hawaii. I love your site! Can you identify my bug?
Though your photo is blurry, it is unmistakenly a Swallowtail Caterpillar. We are almost certain it is the Citrus Swallowtail or Chinese Swallowtail, Papilio xuthus. It is an introduced species and supposedly the only swallowtail in Hawaii.
