Mompha jurassicella
Mompha jurassic ella is a butterfly (moth ) from the family of Frans moths ( Momphidae ).
Features
The moths reach a wingspan of 11-13 millimeters. The front wings are gray-brown and have in the Diskalregion an ocher drawing. This drawing is unclear, especially in the males. It is brownish gray in contrast to the similar types Mompha divis ella, Mompha bradleyi and Mompha confusella more.
In the males, the distal saccule has a slightly curved sharp tip, which does not reach the top of the cucullus. The aedeagus has three different lengths Cornuti. The left one is the shortest. He is very slender and distally provided with tiny needles. The right Cornutus is the longest. He is slender and hook-shaped at the top. The mean cornutus has a forked tip. The genital armature similar to that of Mompha divis ella, but it differs in the shorter and more abruptly tapering saccule and the different length of the aedeagus Cornuti.
In females, the eighth tergite is not sclerotized about 1.5 times as wide as long, which is rear part. The sinus vaginalis is slightly narrower than the widest part of the ductus bursae. The rear portion of the ductus bursae is about as long as the front portion. The beginning of the ductus seminalis is small and oval, it is located in the rear portion of the ductus bursae. The shape and the sclerotisation Tergits 8 and the length of the rear part of the duct bursae are characteristic of the species.
Dissemination
Mompha jurassic ella is located in Western Europe. In the east, the range extends into Switzerland.
Biology
The caterpillars develop on shaggy fireweed (Epilobium hirsutum ). From the beginning of August, they feed in the pith of the stem and causes an up to 25 centimeters long, mostly unbranched burrow. Up to three feeding tunnels have been found in a single plant. The courses are usually separated vertically. The moths fly from late August to October, the winter and fly again from March to April.
System
The species was first known from Switzerland and had because of the unknown whereabouts of the type material and the lack of first description, which did not allow for differentiation from species of the divis ella complex, long time an uncertain taxonomic status ( incertae sedis. Sinev took 1999 as lectotype marked copy of Laverna jurassic ella in the collection of the Natural History Museum in London. It proved to be conspecific to Mompha subdivisella.
From the literature, the following synonyms are known:
