Chrysoclista lathamella is a butterfly ( moth ) fromthe grass leaf miner family (Elachistidae).

features

The moths reach a wingspan of 11 to 13 millimeters. C. lathamella differs from Chrysoclista linneella , Chrysoclista splendida and Chrysoclista abchasica by the dark border on the front and rear edges of the forewings. Both edges merge in front of the middle of the wing, so that the basic orange color is divided into two spots. The basal spot is smaller and lies completely below the costal fold.

The genital armature of the males is similar to that of Chrysoclista splendida , but the Gnathos arms are straighter, slightly widened distally and more thorny. The blades taper apically much more. The anellus lobes are less slender and about half as long as the valves. The aedeagus is only slightly curved.

The genital armature of the females is similar to that of Chrysoclista splendida , but the sclerotization of the eighth tergite is reduced to two narrow, curved, lateral bands. The antrum is funnel-shaped and the ductus bursae is almost twice as long as the corpus bursae.

Similar species

A similar species is Chrysoclista zagulajevi , the distinguishing features are described there.

distribution

The species is widespread in Northern and Central Europe , but only occurs very locally. The species is absent on the Iberian Peninsula , Italy and the Balkan Peninsula .

biology

The caterpillars develop on white willow ( Salix alba ) and sal willow ( Salix caprea ); may also come Salix cinerea ( Salix cinerea ) and crack willow ( Salix fragilis ) into consideration. The way of life of the caterpillars is identical to that of the caterpillars of Chrysochlista linneella . The species forms one generation per year, moths were collected from June to August. Occasionally there are massive occurrences of butterflies, these then sit on the branches of old willows facing the water.

Systematics

For a long time, two species were grouped under the names lathamella or bimaculella . A close examination of the type specimen of C. lathamella in the Natural History Museum led to the result that this specimen must belong to a smaller and more widespread species. This species was consequently described as C. razowskii Riedl , 1965. The species with the larger butterflies is only distributed in Central Europe and was described as C. splendida Karsholt , 1997.

The following synonyms are known from the literature:

  • Glyphipteryx lathamella Fletcher , 1936
  • Tinea bimaculella Haworth , 1828
  • Chrysoclista razowskii Riedl, 1965: 456.
