Mompha lacteella is a butterfly ( moth ) fromthe fringed moth family (Momphidae).

features

The moths reach a wingspan of 11 to 13 millimeters. The head is beige, the third segment of the labial palps has brown median and subapical rings. The thorax and tegulae are beige. The forewings are gray-black with some large, irregular, orange-brown stripes and some white spots. At the base of the wing there is a large beige spot on the inner edge of the wing. It has the same coloration as the thorax and is surrounded by clusters of protruding scales on the costal fold and near the inner edge of the wing. Large clusters of protruding black scales are present in front of the center and below the costal fold. A white costal spot is at 3/4 of the forewing length. Opposite on the inner edge of the wing there is a white spot, which is provided with protruding scales distally . The apical area is gray-black, with a few white lines reaching into the fringed scales. The hind wings have a dark gray sheen.

In the male, the cucullus is about five times as long as it is wide. The saccule is quite slender and as long as the cucullus. It tapers slightly to a blunt apex. The Gnathos is weakly triangular. The anellus lobes are more than half the length of the aedeagus and distally dilated and lobed. The aedeagus is provided with two cornuti; one is long and very slender, the second is short and fork-shaped.

In females, the genital armature of Mompha ochraceella is distinguished by the wide and almost square antevaginal lamella, the inverted V-shaped postvaginal lamella and the considerable sclerosis in the anterior part of the ductus bursae.

Similar species

A similar species is Mompha propinquella , this differs from M. lacteella by the white head and the white thorax as well as by the white base on the upper side of the forewing.

distribution

With the exception of the extreme south, the species is widespread in Europe. In the east the distribution area extends over Asia Minor , the Caucasus , the East Transcaucasia and over the south of Siberia to the Russian Far East .

biology

The caterpillars develop on shaggy willowherb ( Epilobium hirsutum ) and mountain willowherb ( Epilobium montanum ). Between March and April, the caterpillars create a large space mine in one of the lower leaves, which covers most of the leaf. The caterpillars usually move to a new mine. The caterpillar droppings have the shape of relatively large black granules and are either distributed over the mine or concentrated in the middle. The moths fly from mid-June to late July, according to other sources from May to August. The moths come to light .
