The adult beetles are nocturnal and attracted to lights; the larvae generally remain in the soil, often feeding on plant roots.[1]

In order to identify species, the parameres of the male must be pulled out of the abdomen and examined. This process should be done carefully, because the parameres are quite fragile, "almost parchment-like".[1]
