Honeylocust is considered the alternate host of this non-native moth in much of the U.S. However, it’s the primary host in Ohio where mimosa trees (a.k.a. silk trees) (Albizia julibrissin) are rare.

Why do Osage orange trees, Kentucky coffeetrees, and avocado trees have such large seed packages? In all cases, what we see now was shaped by animals that no longer exist; they are extinct.
