Gulf Fritillary larva and butterfly
I live in Ventura California and saw this caterpillar in a local park a few months ago (early spring). I thought it was a Gulf Fritillary larva until I saw a confirmed Gulf Fritillary larva on your website. Mine looks redder and does not have a orange head. What does it eat? I can’t find this butterfly in any of my family’s bug books, can you help identify it? thanks for your help,
Both your caterpillar and butterfly are Gulf Fritillaries, Agraulis vanillae. The caterpillar feeds exclusively on Passion Vine. The adults take nectar. Hogue describes the caterpillars as slate gray or purple on the back with burnt orange stripes on the sides.
