Voluble Dart - Agrotis volubilis

Voluble Dart - Agrotis volubilis
Ailsa Craig, Middlesex, Ontario, Canada
June 1, 2005
At garage light after midnight. I think this is an Agrotis, perhaps A. obliqua or A. volubilis (compare images). I didn't see the hindwings. Maybe the early date will help distinguish it? - most dart moths appear in Aug/Sep around here.

Update: changed title from "undetermined dart" after Bob's ID.

Mot Likely Agrotis volubilis.
According to both Handfield, and Lafontaine's MONA Fascicle, dates can't be of help here. But Lafontaine limits A. obliqua to dry boreal forest, and his map showing specimens that he examined places them safely to the north of you (I think he examined every specimen in the Canadian National Collection and in several other large collections). On the other hand, A. volubilis should be common in your area. Thus, while it might not be possible to specify the species from the photograph, I'd be very comfortable in doing so in this case based on biogeography.

A. volubilis
Sounds good to me. Thanks for the info, Bob. I see there's a couple of "southern" records of A. obliqua from Gatineau Park (Quebec) and near Plattsburgh (northern New York); both areas are several hundred km northeast of my place - i.e. safely north, as you said.
