Cosmopterix crassicervicella is a butterfly ( moth ) from the family of cosmopterigidae (Cosmopterigidae).
features
The moths reach a wingspan of 8 to 9 millimeters. The antennae have a broken white line that extends from the base to 1/3 the length of the antennae. Two white sections made up of two segments are 3/4 of the length of the antennae. They are separated by two brown segments. The white subapical ring consists of three segments. The forewings are brown. The basal region is drawn with five narrow, white lines. The costal line extends from the first third of the basal region to the inner one. shiny metallic band. The subcostal line begins at the base of the wing and is curved inward. The midline is short and lies above the anal fold. The subdorsal line is slightly longer than the midline and further away from the base of the wing. The dorsal line extends from the base of the wing to over the center of the wing. At the wingtip there is a white line that is narrow in the middle and can also be interrupted. The fringed scales are brown. The hind wings are gray-brown. The abdomen is dorsally brown, segments 2 to 5 are dorsally ocher yellow to orange-brown.
In the male, the right brachium is hook-shaped and has a rounded tip. It's about eight times longer than the one on the left. The blades are almost triangular and have a concave upper edge. The caudal margin is slightly convex . The valvellae are slender and tapered near the base. They are curved and have a sharp point. The aedeagus is very slender and bottle-shaped. The front part is slightly curved and has a sharp point. The posterior part is very short and widens slightly distally .
In the females, the rear end of the 7th sternite is very flat, arched. The 8th segment is three times as wide as it is long. The ostium is rounded and sickle-shaped sclerotized . The sterigma is oval. The ductus bursae is one and a half times as long as the corpus bursae. The corpus bursae is egg-shaped, the signs are either very small or absent.
Similar species
Cosmopterix crassicervicella differs from Cosmopterix attenuatella by the shorter white line on the antennae, the wider fore wings (eight times as long as it is wide) and the short costal line.
distribution
The species is native to southern Europe ( Spain , Portugal , France , Sicily , Greece , Crete ), Asia Minor , Transcaucasia , North Africa , the Canary Islands and the Middle East .
biology
The caterpillars develop on cyper grasses ( Cyperus ) and mine in the leaves, with the entire leaf being taken up by the mine up to the tip. The caterpillars create a silky feeding tunnel to hide there during the feeding breaks. The mine is folded up at this point. They pupate inside the mine in a web chamber, which causes the sheet to be folded. The species forms two generations a year, the moths fly from mid-April to mid-June and from late August to late October.
