I have usually taken this species at the same place, about one or two specimens a year, and always within ten yards of the place where I first took it six years ago. The trees in the immediate vicinity were Gleditschia triacanthos, Ulmus americana, Prunus serotina and Celtis occidentalis, but it may have fed as larva upon some weeds or shrubs growing near. All of my specimens were taken about the 8th or 10th of July. This year, however, I have captured (June 14th) two specimens (perfectly fresh) on Gleditschia triacanthos at another place, where the nearest tree was Celtis occidentalis, growing some thirty yards away. Its larva and food plant, however, are not yet by any means certainly ascertained.
