features
butterfly
The most striking feature of the moths are their mostly transparent wings, on which only the wing veins , the discal patch and the wing edges are scaled. In their external appearance they resemble honey wasps ( Masarinae), some sawfly species (Tenthredinidae) or real wasps (Vespinae). This mimicry protects them from predators. The moths reach a wingspan of 16 to 25 millimeters. In the area of the apex of the forewings, clear yellow longitudinal stripes stand out. In the middle there is an elongated black-brown discal spot that extends from the front to the rear edge. The hind wings have a very narrow, dark band and a small black-brown discal spot. The antennae are black, yellow on the outside. On the segments two, four, six and seven of the black abdomen in the males there are yellow, golden yellow or orange yellow rings. Segments two and five have spots of the same color. Female moths show two, four and six equally colored rings on the segments, which are usually a little wider. They also have a small orange-yellow spot on the third segment. The head as well as the vertex and the sides of the thorax are hairy orange-yellow. The anal tufts are strongly developed and also of an orange-yellow color.
Similar species
Chamaesphecia anellata has more brightly colored orange-yellow apical stripes and Chamaesphecia proximata has more rounded wings.
Geographical distribution and occurrence
The sawfly glass-winged winged bird is distributed from southern and southeastern Europe via southern Russia and Transcaucasia to Central Asia. However, it is missing on the Iberian Peninsula . In the German-speaking area he was reported from Lower Austria and Eastern Switzerland . The main habitat of the species are dry, hot ruderal areas , abandoned vineyards and rocky steppes.
Way of life
The diurnal moths fly from May to July. They are particularly active in the afternoon and then like to visit the flowers of various plants. In particular, they have been observed on St. John's wort flowers ( Hypericum perforatum ). The caterpillars live as an annual in the rhizomes of various types of mullein ( Verbascum ). Occasionally they have also been found in figwort ( Scrophularia canina ). In spring they pupate in the upper part of the rhizome in a cocoon that protrudes a few millimeters above the surface of the earth.
