About Agonopterix robiniella Packard, 1870
Agonopterix robiniella, commonly known as the four-dotted agonopterix moth or locust leaf roller, is a moth species in the family Depressariidae. It is native to North America, with recorded occurrences ranging from Nova Scotia to Georgia, westward to Oklahoma, and northward to Illinois, Michigan, and southern Ontario. This species has a wingspan of approximately 16 to 20 mm. Its forewings are yellow, mottled and overlaid with brick red, and speckled and shaded with fuscous and black. Two black discal spots are present at the basal third of the forewings, and a poorly defined dark band sits just before the termen. A series of indistinct blackish spots runs along the costa and around the termen. The hindwings are greyish fuscous, with a narrowly blackish fuscous terminal edge. Adult moths are active from June to October. The larvae feed on the leaves of Robinia pseudoacacia. Larvae have a green body, a thin pale band across each abdominal segment, and a black head.
