Most dates of collection are from June to September, but in the 

 West there are a number of dates in April, May, and October, two in 

 March, and one in November. Most of the March to May specimens 

 are from the San Francisco area. Noteworthy early and late dates 

 of capture in the West are: March 21 at Pacific Grove, Calif.; March 

 28 at Woodacre, Calif.; April 29 at Berkeley, Calif.; April 30 at Oak- 

 land, Calif.; April 30 and May 1 at Workman Creek, Sierra Ancha, 

 Ariz.; May 6 at Robson, B. C; October 19 at Chilliwack, B. C, and at 

 Wellington, B. C. ; October 22 at Cultus Lake B. C. ; and November 8 

 in hills back of Oakland, Calif. Early and late dates of capture in 

 the East are: May 15 at Ottawa, Ont. ; May 26 at Isle au Haut, 

 Maine: May 31 at Rangeley, Maine; September 18 at Rockcliffe, 

 Ont.; September 20 at Calais, Maine; and September 24 at Kentville, 

 N. S. Judging from the data on the pin labels and from our own 

 relatively infrequent captures, the species seems to occur mostly 

 around northern Coniferae. 



Reared specimens comprise: 27 reared lots from Choristoneura 

 fumiferana, 2 from Lambdina fiscellaria, 1 from INepytia canosaria, 

 and 3 from undetermined Lepidoptera. 



This species is transcontinental in the Canadian zone and occurs 

 locally in the Transition zone. Adults occur mostly from late spring 

 to early fall. The usual hosts are Lepidoptera on northern Coniferae.
