GRAPTA Kirby. 



G. interrogationis Fab. Occurs throughout the State and throughout 

 the season; not uncommon. The adult hibernates, begins to oviposit 

 in May and there are three broods. It occurs in two forms, "fabricii" 

 and "umbrosa," which are not seasonal, but may and do occur to- 

 gether in midsummer. The larvae feed on "Celtis," elm, hop, nettle, 

 basswood and other trees.
