Features
The moths reach a wingspan of 17-21 millimeters. The head is bright yellow, the thorax yellow. The tegulae are edged dark gray brown and yellow on the inside. The front wings are deep yellow and have a dark brown Costalstrich which is paler towards the wing tip. A dark brown oval spot is in front of the wing center, it ranges from Costalstrich almost to Costalfalte. A clump of dark brown protruding scales located above and below the Costalfalte itself. A dark brown stain with a tuft of scales in the center is formed at the inner angle. The base of Costalstrichs, the two dark brown spots and the tuft sheds are framed very narrowly white. The fringe scales are gray-brown. The hind wings shimmering gray brown dark.
In the male the uncus absent; the Gnathos - arms are very short and end in large bubbles, which are covered with rows of prongs. The Tegumen is long and narrows distally. The Valven are long, wide at the base and in the middle narrow. The tip is rounded. The Anellus lobes are large and about half as long as the Valven. They taper distally and have at the top a few blunt spines. The aedeagus is long, narrow, tubular, slightly curved. H. laspeyrella can be distinguished from Heinemannia festivella and Heinemannia albidorsella based on the Gnathos arms. They have nearly the same width as the distal portion of the blades. The aedeagus is busy in the vesica with rows of prongs.
In females, the anal papillae are long and narrow. The posterior Apophyses are about a quarter longer than the anterior Apophyses. The ostium is wide and cup-shaped. The antrum is provided with a pair of short sclerotized ridges. The ductus bursae is long and narrow and the corpus bursae slightly dilated. The widest part is more or less granular. The eighth tergite is rectangular and about half as long as wide. The junction area of ductus bursae and corpus bursae is very finely granulated. The corpus bursae is egg-shaped and has no Signum.
Similar Species
In H. laspeyrella head and thorax are yellow. In conjunction with the deep yellow forewings, the type are distinguished from Heinemannia festivella and Heinemannia albidorsella.
Dissemination
Heinemannia laspeyrella is native to North, Central and Eastern Europe. In the east, the range extends up to the Urals and south Siberia.
Biology
The caterpillars were detected in the pea -like pea ( Lathyrus pisiformis ), the Spring pea ( Orobus vernus ) and clover species ( Trifolium ). Moths were trapped in blackness Santander pea ( Lathyrus niger). The caterpillars evolve from July until the first half of August, and eat the seed pods. It can live in a sleeve up to six caterpillars. The adult caterpillars overwinter in the bark of nearby trees. It makes only one generation per year, the moths fly from mid-May to early July.
