Biology and phenology

In the moist and shady habitats of several vegetal formations, like secondary forests and coastal forest edges in Brazil, you'll frequently find adults of this species. They're attracted to fermented fruits and other decaying materials.^[2]

Larvae of this species can feed on Poa plants.^[3] Specifically in Poa annua,^[4] Digitaria sanguinalis and Stenotaphrum secundatum.^[5]
