This is a Question Mark butterfly: eggs, caterpillar, chrysalis, and adult. Shown with it’s host – Elm tree. There are many butterflies in this family, called “anglewings” -Comma, Asian, Eastern, Southern, Mexican, Giant, and Hoary – just to name a few!
The adults feed on fermenting fruit, tree sap, dung, carrion and rarely flowers – when they feed on fermenting fruit, they can appear to be intoxicated and are reluctant to fly even when touched! We think of butterflies as beautiful and associate them with flowers…but they’re not always so sweet ; )
