Mompha terminella is a butterfly ( moth ) fromthe fringed moth family (Momphidae).
features
The moths have a wingspan of 7 to 9 millimeters. The head is dark brown and has a slightly purple sheen. The forehead ( frons ) is ocher white. The antennae are dark brown, the antennae tip consists of about eight white segments. The thorax is blackish brown and has a slight purple sheen. The forewings are dark orange in color. A lead-gray spot extends from the wing base up to 1/3 of the forewing length, at the wing base it extends from the Costa loader to the inner edge of the wing. There is a black spot inside the spot. A narrow brown costal line extends from this black spot to a white costal spot at 3/4 of the forewing length. A lead-gray, golden, shiny spot is located between the inner edge of the wing and the anal fold. Outside it is surrounded by a clump of protruding black scales . A similar spot is on the inner corner , opposite to it is a small white subcostal spot . The apex is black-brown and has shiny lead-gray lines on the outer edge. The hind wings are dark gray-brown.
In males, the cucullus is short and broad. It is one and a half times as wide at the base as at the top. The apex is rounded. The saccule is shorter than the cucullus, it is curved and has a rather blunt apex. The uncus is long and has a hook-shaped tip. The gnathos has the shape of a needle-like ribbon. The anellus lobes are short and clipped and provided with needles. The aedeagus is short and strong. It has a long, pointed cornutus and a needle-studded area.
In females, the 8th tergite is rectangular and only slightly sclerotized . The lobes of the 8th sternite are large and heavily sclerotized. The sterigma is bulbous and tapered in front. The ostium is wide and funnel-shaped. The ductus bursae is S-shaped and about one and a half times as long as the corpus bursae. The widest sclerotized section is connected to the ostium and tapered in front. The corpus bursae is oval and has two large sickle-shaped signs.
Similar species
Mompha terminella differs from the similar species Mompha locupletella by the smaller wingspan, the black spot within the gray spot on the wing base and the two subdorsal spots.
distribution
The species is native to northwest Europe and Central Europe . In the east the distribution area extends to the Russian Far East . The species has also been detected on the east coast of North America .
biology
The caterpillars develop on large witchweed ( Circaea lutetiana ), alpine witchweed ( Circaea alpina ) and middle witchweed ( Circaea intermedia ). The species forms only one generation a year. The caterpillars live from the first half of August to the first half of September (or from June to July) and mine in the leaves. The mine begins in the form of a narrow whitish feeding tunnel that forms a few circles or semicircles around the egg-laying site. Later mines are greenish white. They then have a conspicuous feeding tunnel in which the caterpillar droppings are shown as a black line. Sometimes both feeding tunnels are connected to each other and form a large open mine in which the lines of the caterpillar droppings indicate the original feeding tunnels. The caterpillars often leave the original spiral mine to start a new mine nearby or on a different sheet. The caterpillars pupate in a whitish cocoon that is spun onto a leaf or in the litter layer , and occasionally in the mine. The moths fly from July to August (or from May to June).
