Pennsylvania, Ohio. The larva does not live in Cornus, as might be assumed, but in Doellongeria umbellata 
(a white aster), in damp, swampy places in the stalk and the lower parts; in May it eats a few inches upwards 
and constructs a pupal window which can be easily pierced by the imago after the three weeks' pupal stage. 
From the middle of May to the middle of July, the 3$ flly to the blossoms in the sun in the morning, while 
the lazy can be easily taken away with the killing-bottle, as they remain sitting on the food-plant or close 
by. In looking for them, the stalks occupied by them easily break off; larvae not yet having pupated in May 
are sure to be infested by parasites.
