Mompha langiella is a butterfly (moth ) from the family of Frans moths ( Momphidae ).
Features
The moths reach a wingspan 9-11 mm. The head is dark brown and shows a slight violet sheen. The forehead ( frons ) is white. The sensors are in the first third dark brown, striped gray and dark brown in the middle third and the last third gray. The thorax and forewings are brownish black and have a purple sheen. An irregular white spot is outside the wing center, sometimes a few white scales are available at 1/ 3 of the forewing length of the anal fold. The Costa loader is speckled in the outer half of the wing and at the apex with sparse white scales. The hind wings are gray-brown. The abdomen is brownish black. The after tuft is gray and white in the males with the females.
In the male the uncus is slim and has a rounded tip. The cucullus is slender, subapical at its widest and has a blunt apex. The saccule is longer than the cucullus and tapers to a sharp, slightly curved tip. The Gnathos is sclerotized wide and weak. The Anellus - lobes are small and rounded. The aedeagus is slender and has a fairly large cornutus. This is at the base and wide at the apex slender and curved.
In females, the ostium is very wide and cup-shaped. The rear third of the ductus bursae is broad, weakly sclerotized and provided with two short strongly sclerotized edges. The front portion is tapered and has large sclerites. The seminal duct starts at about 1/3 the length of the duct bursae. The corpus bursae is oval and tapers slightly to the rear. It has two large crescent-shaped signals.
Dissemination
Mompha langiella is widely used in Europe, except the Mediterranean. The species occurs also in the Caucasus.
Biology
The caterpillars develop at Big witchweeds ( Circaea lutetiana ) Alpine witchweeds ( Circaea alpina), shaggy fireweed (Epilobium hirsutum ) and, occasionally, the mountain willow herb (Epilobium montanum ), Kleinblütigem fireweed (Epilobium parviflorum ) and Schmalblättrigem fireweed ( Chamaenerion angustifolium ). In June and July the caterpillars nate in the leaves, rarely also in the seed capsules. The greenish-white mine begins as a spiral burrow, an irregular or broken black line is in the middle of Raupenkot. Later the caterpillars lay near or on another sheet to another mine. The second mine is very soon to a place or mine several interconnected space mines. The Raupenkot initially has the shape of a wide, irregular line, later the Kotkrümel are in place mine is distributed visible. The caterpillars are partly due to the plants quite numerous, so that the leaves are often completely covered by mines. The caterpillars pupate in a leaf attached to a whitish cocoon or in the litter layer on the ground. It is formed a generation a year. The moths fly from August, hibernate and can be observed in the following year to April.
