Flavicaput Spuleria is a butterfly from the family of elachistidae (Elachistidae).

features

The moths reach a wingspan of 12 to 14 millimeters. The head is light yellow and has a narrow dark brown line on the sides. The antennae are dark brown and slightly curled in the apical half. Thorax and tegulae are dark brown and have a purple sheen. The forewings shine dark brown and have a bluish tinge. Two small and one indistinct tufts of scales are located in the first and second third of the inner margin of the forewing. The fringed scales are dark brown. The hind wings shine gray-brown and the fringed scales are gray-brown.

In the males, the uncus is very short. The Gnathos arms are short and spherical at the tip and have rows of spines. The tegumen is large and narrows distally . The blades are long and rounded at the tip. The anellus lobes are large and wide and very pointed at the apex. The aedeagus is long and straight. It is tubular and pointed distally. There are rows of spines in the vesica.

In females, the ostium has two sclerotized and curved margins on the sides . The antrum is sclerotized and curved in the middle. The ductus bursae and the posterior part of the corpus bursae are finely granulated. The sign is elongated.

distribution

Spuleria flavicaput is native to Europe and Asia Minor .

biology

The caterpillars develop on single-fluted hawthorn ( Crataegus monogyna ) and double-fluted hawthorn ( Crataegus laevigata ). They drill into the young side branches in summer and early autumn. The feeding passage begins at the fork of the branch and leads into the marrow . It extends about 30 millimeters towards the tip of the branch and bends at the end towards the surface of the branch. The exit hole is oval and is usually at the bottom of the branch. It is partially covered with a thin layer of bark. Before pupation, the caterpillars close the feeding passage near the exit hole with a web. Pupation takes place in late autumn. According to Sagittarius , the caterpillars live from September to March / April. The moths fly around the hawthorn branches in the morning sun from May to June. During the day they sit in the flowers of the hawthorn, where they can be roused by tapping.
