Tersa Sphinx Caterpillar

Dear Baffled IL Family,
This is the Caterpillar of a Tersa Sphinx Moth, and its false eyespots are very effective at scaring potential predators.  According to Sphingidae of the Americas: “Larvae also feed on
Borreria, Catalpa and Manettia spp. and Smooth buttonplant (Spermacoce glabra) and starclusters (Pentas species). They are also recorded on joe-pie weed and Hamelia patens.”  Many gardeners grow Pentas in the garden.

Wow! Quick response time. Thank you so much. Enjoy your day!
