features

butterfly

The moths reach a wingspan of 16 to 26 millimeters. The sexes do not differ in color. The basic color of the upper side of the forewings is brown-gray to reddish brown. The middle field stands out black-brown and is clearly delimited by narrow white transverse lines, the outer one of which is jagged. The whitish wavy line is usually indistinct. A small area near the apex is highlighted in light gray and contains a short black dividing line. The upper side of the hind wing is colored white-gray.

Caterpillar

Adult caterpillars are stocky and have short bristles. They have a greenish or brownish color and show fine gray lines on the back and side back, which are expanded to small dark gray spots in the segment incisions. The wide white side stripe is lined with dark. The spiracles are black.

Distribution and occurrence

The distribution area of ​​the tooth restraint capsule stretches from the Iberian Peninsula through all of Europe including the British Isles and further east to the Urals and Kazakhstan . The species has also been found in Morocco . The tooth grid capsule tensioner prefers to colonize sunny slopes, forest edges, alluvial forests, poor grasslands and wasteland. In the Alps it rises to around 2,400 meters.

Way of life

The tooth rust capsule tensioner forms one generation per year in most of the occurrence areas, the moths of which are mainly found from the end of July to the end of August. In southern regions, specimens from a second generation were found in September or October. The moths only fly when it is completely dark and sometimes visit artificial light sources very late at night and sometimes irregularly . The main food of the caterpillars are the flowers and fruits of the red ( Odontites vulgaris ) and the yellow tooth rust ( Odontites luteus ). Sometimes they are also found on the common eyebright ( Euphrasia officinalis rostkoviana ). The young caterpillars stay hidden in the fruit capsules; when they grow up they live freely on the fruit heads of the food plant. The species overwinters as a pupa and usually flies over several times.
