About Eupithecia abbreviata Stephens, 1831
Eupithecia abbreviata Stephens, 1831 is a moth species with an adult wingspan of 19 to 22 millimeters. The forewings measure 10 to 12 millimeters in length and are elongated, with a distinct ochreous tinge. Strong dark vein dashes are present proximal to the postmedian line, and these dashes are particularly well developed on the median veins. Hindwings are small, with a distal margin that is almost straight from near the apex to behind the middle. Antennal ciliation is not very long. A weakly marked aberration, ab. hirschkei Bastelberger, is commonly found in the Middle Rhine district. Mature caterpillars are smooth and slender, with body colour ranging from light grey to yellow-grey. They have large, dark brown diamond-shaped spots on the back, and dark brown, strongly jagged side stripes. Adult moths fly during April and May. This species inhabits oak forests, mixed oak forests, oak avenues, and parkland. In the Southern Alps, it can be found at elevations up to 1100 metres. The larvae feed on oak and hawthorn.
