About Anacampsis tristrigella (Walsingham, 1882)
Anacampsis tristrigella is a moth in the Gelechiidae family. It was described by Thomas de Grey, 6th Baron Walsingham, in 1882. It is native to North America, where it has been recorded in Alabama, Arkansas, Manitoba, Massachusetts, Mississippi, Ontario, Quebec, Tennessee, and Texas. This moth has a wingspan of approximately 12 mm. Its forewings are greyish fuscous from the base to past the middle of the wing, with a greenish tint visible in some lighting. A steel-grey streak runs along the costal margin, continuing across the front of the thorax. The area of the forewing beyond the middle is very dark brown, and features a transverse white fascia that extends outward at the start of the costal cilia. This fascia narrows at the middle of the wing and becomes slightly wider near the dorsal margin. Beyond the fascia, there are three, sometimes four, white tooth-shaped streaks. Their bases are joined near the apical margin, and they are separated from the steel-grey fringes by a double dark brown line that curves around the apex of the wing. The hindwings are brown, with grey fringes. They have an oblique shape, and are barely notched below the apex. The base of the hindwing costal margin is steel-grey. The larvae of Anacampsis tristrigella feed on Corylus americana.
