My identification of this species is based on comparison of my photos with specimens in the Canadian National Collection in Ottawa, to which access was kindly arranged by Dr. P.T. Dang of the Canadian Forest Service.  At present, my identification is tentative pending expert confirmation based on the collected specimen shown above right.

Anacampsis tristrigella is one of half a dozen species of Anacampsis known to occur in the Ottawa area.  Several species in this genus have a bright white line marking off the outer third of the forewing, typically a little thicker at the costa.  The inner 2/3 of the forewing is yellowish gray-brown in color, while the outer 1/3 is very dark brown to black.  A. tristrigella is distinguished from other similar species by the three white marks at the outer margin between the point of the wing and the anal angle.  Overall, it has a very sleek, striking appearance for a moth of wing length of approximately 8 mm.

I have no information on the larval host plant or life cycle of this species.

I have photographed this species in 2003, on 23 and 27 July.
