Stagmatophora heydeniella is a butterfly ( moth ) from the family of cosmopterigidae (Cosmopterigidae).

features

The moths reach a wingspan of 7 to 9 millimeters. The head shines bronze gray. The neck collar is dark gray. The antennae have a dark brown shimmer and two white subapical rings. The thorax and the tegulae shine bronze-gray. The forewings are bright orange in the middle and shine dark brown in the basal quarter. A slightly sloping inward silvery band is 1/5 of the forewing length. It does not extend to the inner edge of the wing and has a dark brown border on the outside. The orange area is marked with five silvery spots with dark brown edges. This drawing includes two costal spots, a subcostal spot, a spot at the inner corner and a very small central spot. The two outer spots are tinted pale gold. The last third of the forewings is dark brown. There is a large, silvery spot that shines slightly purple at the apex . The fringed scales are dark brown on the costalader and paler at the apex and in the direction of the wing inner edge. The hind wings are gray-brown. The abdomen has a gray-brown sheen.

In the males, the tegumen is long and rather narrow. The right brachium is long and has a broad base. It tapers in the distal half. The apex is rounded and has a hook-shaped bar. The blades are semicircular, the inner edge has a flat hump. The right valvella tapers distally and has a blunt apex. The left valvella is completely connected to the aedeagus and has a number of small spines. The aedeagus has a bulbous base and is almost round. He has a large, broad cecum penis. The tubular part is long, curved in front of the middle and widened apically .

In the females the 8th segment is short and strongly tapered before the rear end. The ostium has a V-shaped sclerotization. The sterigma is egg-shaped. The ductus bursae is narrow and only a third as long as the corpus bursae . The latter is elongated and has two large, funnel-shaped signs. Both signs are toothed and the same size.

distribution

Stagmatophora heydeniella is distributed in Europe from France in the west, across Central Europe and the Balkans in the south to the European part of Russia.

biology

The caterpillars develop on Heil-Ziest ( Stachys officinalis ), Wald-Ziest ( Stachys sylvatica ) and Yellow Ziest ( Stachys alopecyrus ). They mine in the leaves from August to September, creating irregular space mines with many short feeding channels. Most often there are several mines in one sheet. Later, the caterpillars create feeding tunnels on the underside of the leaf along the leaf center rib. These are lined with spider silk and serve as shelter. One end of this shelter opens into the mine. The caterpillar droppings are placed in the middle of the mine and sometimes ejected. The caterpillars pupate in a white cocoon either in the shelter on the underside of the leaf or in a fold on the leaf edge. The pupa hibernates. The moths fly from May to June.
