Adult punctuation butterflies typically prefer three types of food sources: tree sap, decaying fruit and carrion. As for luring these butterflies to your own garden, the most important thing to know is that this genus of butterflies is rarely found collecting nectar from flowers. You’ll see these butterflies more frequently in wooded areas, as their caterpillars host almost exclusively on trees.

In the west, you’ll see hoary commas (Polygonia gracilis) and satyr commas (Polygonia satyrus). They all look very similar and are instantly recognizable with their sharp wing angles, bright orange coloration on top, and drab underwings with comma markings.
