This species was abundant from the middle of June to the end of July, and I observed the females ovipositing on our shade trees (maple) in various parts of the city. It appears to prefer trees which have been recently transplanted, and which are naturally not so vigorous as those which grow undisturbed. My next-door neighbor set out several young trees, from one to two inches in diameter, and upon these I took several specimens. On the other hand, I observed them, beyond the city, ovipositing in quite large and old maples, and even upon the limbs of an old tree which had been broken and blown down.
