A slightly inclined inwards silvery binding is located at 1 /5 of the forewing length. It is not enough to wing inner edge and is outside margins dark brown. The orange area is drawn with five dark brown edged silvery spots. For this drawing includes two Costalflecke, a Subcostalfleck, a stain on the inner angle and a very small center spot. The two outer spots are pale golden toned. The last third of the forewing is dark brown. There is a large silvery spot, the violet light shines at the apex. The fringe scales are paler on the Costa loader and dark brown at the apex and towards the wing inner edge. The hind wings are gray-brown. The abdomen shining gray-brown.
In the males, the Tegumen is long and quite 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 Valven are semi-circular, the inner edge has a flat hump. The right Valvella tapers distally and has a blunt apex. The left Valvella is fully connected to the aedeagus and has a row of small spines. The aedeagus has a bulbous base and is almost round. He has a big penis wide cecum.

Dissemination
Stagmatophora heydeniella is widespread in Europe from France in the west, across central Europe and the Balkans in the south to in the European part of Russia.
Biology
The caterpillars develop on healing Betony ( Stachys officinalis), forest Betony ( Stachys sylvatica) and Yellow Betony ( Stachys alopecyrus ). You nate from August to September in the leaves, with irregular space mines with many short feeding transitions occur. In most cases there are several mines in a leaf. Later the caterpillars put on the underside of leaves along the leaf midrib feeding tunnels. These are lined with spider silk and serve as shelter. One end of the shelter opens into the mine. The Raupenkot is placed in the center of the mine and partially ejected. The caterpillars pupate in a white cocoon either in the shelter on the underside of leaves or in a fold on the leaf margin. The pupa overwinters. The moths fly from May to June.
