The red dice thick-headed butterfly ( Spialia sertorius ) is a butterfly from the family of the thick-headed butterfly (Hesperiidae).
features
The moths reach a wingspan of 22 to 24 millimeters. They have black-brown wing tops on which many white cube spots can be seen. The outer edges of the wings are colored in interrupted white and black. Behind it run parallel lines of small, white spots. The undersides of the wings are red-brown, more rarely dark brown or greenish in color and have numerous dice marks.
The caterpillars are about 20 millimeters long. They are dark brown to black in color and have two yellow longitudinal lines that are jagged inwards to the left and right of the back. You have a lot of medium-length, white hair.
Occurrence
The red cube-headed butterfly occurs in North Africa , South and Central Europe and in West Asia as far as Tibet and the Amur up to an altitude of 1,650 meters. In Europe they are found especially in the south of Central Europe, where they are found in dry and warm areas, such as B. live on dry grass , gravel pits or quarries but also in forest clearings and in bushes. The species is rare.
Way of life
The moths fly to different flowering plants during the day, but they are also often found in puddles where they suck liquid. The males wake up from a raised seat to drive away other moths on approach. Then they return to the same place.
Flight times
The animals either fly in one generation from late May to June; the caterpillars are found from July and after wintering until April, or in two generations from May to June and from July to August. The caterpillars are found from September and after wintering until April and in June and July.
Food of the caterpillars
The caterpillars feed monophag on the small meadow button ( Sanguisorba minor ).
development
The females lay their eggs on the buds of the forage plants. When these bloom, they cover the eggs under the petals. The hatching caterpillars first eat the flowers and only later the leaves. They live in a self-spun web of leaves and hibernate in it as a caterpillar. They do not pupate until the next year, also in their web of leaves.
