butterfly
The moths reach a wingspan of 17 to 23 millimeters. Their front wings are brightly red, red-orange or red-brown pollinated and have only very small transparent windows. The front edge and the narrow band are black-brown, the apex strongly rounded. In the middle, an elongated black discal spot can be seen that extends to the front edge. The hind wings are transparent and show a narrow dark band as well as a small black-brown discal spot. The fringes are lightened on all pairs of wings. The antennae are black-blue in color and are sometimes dusty yellow in the subapical area. The thorax shimmers black and green. There are thin yellowish or whitish rings on segments four and six of the abdomen , which is also black-green . The second segment is almost always unedited. The anus tufts are strongly fan-shaped, black at the edges and broadly red in the middle.
Similar species
The vermilion dock -winged dock ( Pyropteron minianiformis ) is more delicate in overall appearance and has more pointed forewings .
Geographical distribution and occurrence
The red dock-winged winged dock is locally widespread in Central and Southern Europe. The main habitat of the species are meadow valleys, forest clearings, heather areas, sandy slopes and ruderal areas .
Way of life
The diurnal moths fly in June and July, at higher altitudes until August. They like to visit the flowers of various plants, including: thistle ( Cirsium ), rock carnations ( Petrorhagia ), fine ray ( Erigeron annuus ) and clover ( Trifolium ). Male moths also fly to pheromome traps . The maggot-shaped caterpillars live one to two years in the stems and roots of various dock species ( Rumex ). If a food crop is attacked by several caterpillars, they can wither and die. The caterpillars overwinter in the roots or stems and pupate there in spring.
Danger
In Germany, the red dock-winged glass-winged species occurs locally and mostly rarely in the southern and western federal states, but is classified as not endangered on the red list of endangered species . In Baden-Württemberg , however, it is on the pre-warning list.
