Adult ''Pyrophorus'' beetles feed on pollen and sometimes small insects, such as aphids or scale insects. Their larvae feed on various plant materials and invertebrates, including the larvae of other beetles. Eggs are luminous and are deposited either on or in the soil. Larvae, like eggs, are luminous. They grow slowly and pupate after an uncertain period of time, but perhaps several years after hatching.
