Bionomics

The larvae live freely on the leaves of the food plant and hibernates, potentially multiple times. The cocoons are partly spun at straws, but the majority are hidden near the ground in the litter.
The adults are active during the day. This species is noted for its late afternoon aggregations, so-called parking stations in large numbers on flowers and other elevated plant parts.
