Host plants:
The larvae are polyphagous on grasslands and rock vegetation such as horseshoe vetch.
Habitat:
Hoplodrina respersa inhabits rocky, dry grasslands, quarries and other rupicolous, rocky or more rarely also sandy places.
Life cycle:
The half-grown caterpillar overwinters and is active from March. The pupation takes place in May. Moths fly from June to August. The caterpillars are active at night and can be found under rocks or pads of horseshoe vetch and other plants during the day.
Endangerment: regionally endangered or decreasing
Endangerment factors:
Hoplodrina respersa is relatively widespread and has comparatively low requirements. So it is still not threatened existentially despite the decline in preferred habitats.
Remarks:
The total distribution extends across Europe. In addition, it is found in Asia Minor.
