It lives near water sources such as woods, ponds, and marshes, feeds on sap, rotting fruit, salts, minerals, and dung, while its caterpillars eat a variety of trees and shrubs. Adults overwinter in the winter form or migrate south, and the species can be confused with similar commas, but the shape of the comma mark helps tell them apart.

What it eats

Adults rarely visit flowers; they obtain nutrients from sap, rotting fruit, salts, minerals, and dung. Caterpillars feed on a range of host plants including birch, hackberry, hops, nettles, currants, gooseberries, basswood, elm, and clearweed.

Life cycle

Females lay green eggs singly or in small clusters under host-plant leaves and stems. Winter-form adults overwinter, and some individuals migrate south for the winter.

Lookalikes

The dark form can be mistaken for the dark form of the Question Mark butterfly, but the comma mark shape differs. The pale form may be confused with the Satyr Comma, which occurs more to the north and west.

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.
