The brown spot Burnet or maid ( Dysauxes ancilla ) is a moth from the subfamily of the tiger moth (Arctiinae).
features
The moths reach a wingspan of 22 to 25 millimeters. They have ocher-brown forewings on the rear third of which sit two or three larger white points and one small white point. The hind wings of the males are also ocher brown, in the females they are yellow and have a brown border. In their resting position they also protrude a little below the forewings next to the body, which is not completely covered by the wings. In the males, the fore wings cover both the rear and the body. The antennae of the males and females are thread-shaped.
The egg is hemispherical, flattened at the bottom. It is light yellow in color with a shiny surface.
The caterpillars are dark purple with black, brown hairy bristles. The side stripes and the side spine are light yellow. The black-brown head is relatively small.
The doll is brown and has short hair close to the back. The end is bluntly rounded.

Geographical distribution and habitat
They occur in southern and central Europe , east to the Urals . They live in dry and warm ( xerothermal ) areas, such as B. rocky, sunny grassland and limestone slopes with bushes but also vineyards and quarries.
Way of life
The brown spot ram forms one generation per year in the northern part of the distribution area, the moths of which fly from July to August. In climatically favorable areas, such as B. the Southern Alps, a second generation is probably formed. They are nocturnal, but also fly in the late afternoon. They are attracted to artificial light sources.
The caterpillars feed mainly on lichens and mosses but also on various herbs such as z. B .:
- Dandelion ( Taraxacum spec.)
- Field herbs ( Senecio spec.)
- Plantain ( Plantago spec.)
- Lettuce ( Lactuca spec.)
The caterpillars overwinter and pupate in a light web in June.
