A very rare xerothermic species in some parts of Belgium, not observed since a while.
The larva lives on the roots and leaves of different species of herbaceous plants and grasses. Hibernates as a larva in an underground cell, in which it pupates. The adults come to light and sugar.
The adults fly in one generation a year; from early July till mid September.
