American Snout butterflies have black-brown wings with white and orange patches and a squared-off hook tip on the forewing. They hide upside-down under twigs, blend with dead leaves, and migrate from June to October, often after drought and rain. Caterpillars eat hackberry (Celtis) leaves, which can lead to noticeable damage on these trees.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
