About Catocala robinsoni Grote, 1872
Catocala robinsoni, commonly called Robinson's underwing, is a moth species belonging to the family Erebidae. This species was first formally described by Augustus Radcliffe Grote in 1872. It is distributed across North America, ranging from southern Ontario and New Hampshire southward to Florida, and westward to Oklahoma, Missouri and Arkansas. Its northern distribution extends to Illinois, Indiana, and Michigan, where it occurs rarely. The wingspan of this moth measures between 70 and 80 mm. Adult moths are active from July to October, with activity timing varying by location. It is thought that the species produces just one generation per year. The larvae of Catocala robinsoni feed on Carya ovata, Juglans, and Quercus alba.
