Olethreutes arcuella, the arched marble, is a colorful small moth species of the family Tortricidae.
Junior synonyms of this species are:[1]
This species can be found in most of Europe, in the eastern Palearctic realm, and in the Near East.[2]
These moths inhabit woodland, fields, hill pasture and heaths.[3]
Olethreutes arcuella has a wingspan of 14–18 mm.[3] Forewings of these medium size moths have an orange-rufous ground colour, with some yellow patches, a few metallic blue-grey or silver-colored streaks and a wide black marking in the middle, which includes a row of three small, silver colored spots. The hindwings are brown.[3] The caterpillars are purplish- gray to violet-brown and have a yellowish-brown head.[4]
This species is quite similar to Olethreutes subtilana, but has rather narrower wings.
This species usually has one generation (univoltine).[4] The flight time of these day-active moths ranges between late May and August.[3] The caterpillars feed on dead and dried out leaves and similar plant material.[3][5][6] Also pupation takes place in plant debris.[7]
