Concerning Sesia accrni, Mr. Beutenm tiller, in his Mono 

 graph of the Sesiidae, on page 296, writes: "According to 

 Mr. Hulst, the eggs are probably laid at night. The moths 

 emerge soon after sunrise and are on the wing a few minutes 

 after emerging from the pupa-. ' ' 



My observations on this species totally disagree with this 

 statement, and I recount what I have observed. Occasionally 

 we find a lonely example of this species in a woods where dif- 

 ferent species of maple grow. To find them in abundance we 

 must seek the silver maple, Acer dasycarpum Ehrhart, which 

 is extensively used as a shade tree in suburban sections of cit- 

 ies. In Knoxville Borough, near Pittsburgh, nearly all of the 

 streets are lined with this maple. Here I have observed and 

 collected accrni for many years. Often from 50 to 100 empty 

 pupal shells may be seen protruding from the trunk and main 

 branches of a single tree at the end of its period of flight. 

 Females were collected at all hours from noon to 5 P.M. de- 

 positing ova. A female will often distribute from 10 to 15 

 ova on the same tree. There is nothing unusual in its time 

 of emergence. On bright, warm days accrni may be found 

 emerging from 8 to 1 1 A.M. The males, after their wings are 

 developed, which, however, takes more than a few minutes, 

 as stated above, soon fly in search of mates. The females 

 mostly remain on the trunks of the trees till after copulation. 

 On cloudy days very few emerge, and these may be found 

 resting on the trees ; none were seen flying on such days.
