Subfamily ELATERINAE
Tribe Agriotini Subtribe Agriotina Agriotes · Dalopius • Subtribe Pomachiliina Idolus · Leptoschema • Subtribe Synaptina Glyphonyx
Tribe Ampedini Subtribe Ampedina Ampedus • Subtribe Dicrepidiina Blauta · Dicrepidius · Dipropus • Subtribe Melanotina Melanotus • Subtribe Physorhinina Anchastus · Physorhinus
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 yet to accommodate some species (e.g., Ctenicera horni)
Size
1-60 mm(1)
Identification
Peculiar in being able to "click" and jump: if placed on their backs, click beetles use the flexible union of the prothorax and mesothorax (the prosternal spine fits into a groove on the mesosternum) to snap and jump usually falling right side up (in other beetles, the union of prothorax and mesothorax allows little or no movement)

Range
worldwide and throughout NA(1)
Habitat
Found in all but aquatic and the most severe arctic and alpine habitats(1): adults on flowers/vegetation or under bark; larvae in rotten logs or soil
Food
Adults usually eat plants. Larvae eat newly planted seeds, roots, etc., some eat other insects.
