A very rare and very local xerothermic species, known only from older records in HA and NA and not seen for a very long time. Probably extinct.
Hibernates as a pupa.
During the day they are easily disturbed from vegetation. They come to light.
The adults fly in two generations a year from late April till June and again from July till August.
