This Amorpha juglandis from Texas is blue! Also known as the Walnut Sphinx, these larvae are usually green, or rarely yellow and pink, but I haven't seen blue before! This very rough looking larva will hiss and squeak at you when it feels disturbed. Since I'm working on color morphs for my thesis work, this was a really cool caterpillar to get in the mail. I am really excited to start fully running some experiments next summer, I'll be sure to post photos and preliminary results as I go :) #Amorpha #Amorphajuglandis #WalnutSphinx #Texas #Insects #Bug #Sphingidae #Lepidoptera #SphinxMoth #HawkMoth #Entomology #Caterpillar #Larva #SphinxLarva #MothLarva #igclub_butterfly #igcb_mothmondays #insects_of_our_world https://www.instagram.com/p/B3SUZ-agQ4M/?igshid=1m4xh6qy0ld69
