Family ELATERIDAE
Notes:
Ampedus: species with bicarinate pronotal hind angles are sometimes treated in Ectamenogonus Buysson 1893
Ctenicera: in NA, C. kendalli (Kirby) is the only species attributable to this genus; all other species cataloged in this genus are undergoing taxonomic review and will eventually get proper generic placement, with several new genera to be erected to accommodate some species

Food
Larvae: mostly opportunistic predators, some saprophagous; soil-dwelling species mostly predaceous or omnivorous. Agriotes, Limonius, some Melanotus and Selatosomus spp. feed on sprouting seeds and roots of seedlings of grasses, and occasionally on roots and tubers of vegetables.
Adults: Some prey on soft-bodied insects, but many feed on overripe and decaying fruit, nectar, pollen, floral parts, and fungi.
