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

features

The moths reach a wingspan of 11 to 13 millimeters. The forewings are gray-brown and have an ocher-colored markings in the discal region . This drawing is indistinct, especially in the males. In contrast to the similar species Mompha divisella , Mompha bradleyi and Mompha confusella, it is more brownish-gray.

In the male, the sacculus has a slightly curved, sharp tip distally that does not reach the tip of the cucullus. The Aedeagus has three cornuti of different lengths. The left one is the shortest. It is very slender and has tiny needles distally. The right cornutus is the longest. It is slim and hooked at the top. The middle cornutus has a fork-shaped tip. The genital armature is similar to that of Mompha divisella , but it differs through the shorter and more abruptly tapering sacculus and the different lengths of the cornuti of the aedeagus.

In females, the 8th tergite is about 1.5 times as wide as it is long, the rear part is not sclerotized . The vaginal sinus is slightly narrower than the widest part of the bursal duct. The posterior section of the ductus bursae is about as long as the anterior section. The beginning of the seminal duct is small and oval, it is located in the posterior section of the bursal duct. The shape and the sclerotization of the 8th tergite as well as the length of the posterior part of the ductus bursae are characteristic of the species.

distribution

Mompha jurassicella is native to Western Europe . In the east the distribution area extends to Switzerland .

biology

The caterpillars develop on the shaggy fireweed ( Epilobium hirsutum ). From the beginning of August they feed in the core of the stem, creating an up to 25 centimeters long, mostly unbranched feeding tunnel. Up to three feeding tunnels have so far been found in a single plant. The aisles are usually separated vertically. The moths fly from late August to October, hibernate and fly again from March to April.

Systematics

The species was first known from Switzerland and for a long time had an uncertain taxonomic status ( incertae sedis ) because of the unknown whereabouts of the type material and the poor initial description, which did not allow any differentiation from species of the divisella complex . In 1999 Sinev found the specimen of Laverna jurassicella marked as the lectotype in the collection of the Natural History Museum in London . It was found to be conspecific to Mompha subdivisella .

The following synonyms are known from the literature:

  • Mompha subdivisella Bradley , 1951
  • Laverna iurassicolella Reutti , 1898
  • Laverna jurassicella Frey , 1881
