Classification
Kingdom Animalia (Animals)
Phylum Arthropoda (Arthropods)
Subphylum Hexapoda (Hexapods)
Class Insecta (Insects)
Order Coleoptera (Beetles)

Explanation of Names
The word elater means 'driver, hurler' and refers to the elastic power of motion possessed by these beetles(1) (more details here)
Numbers
ca 965 valid spp described from the Nearctic region + an estimated 75-100 undescribed(2); over 10,000 spp worldwide(3)
Overview of our fauna(4):
Family ELATERIDAE
Taxa not yet in the guide are marked (*)
Subfamily CEBRIONINAE
Subfamily ELATERINAE
Subfamily LISSOMINAE
Subfamily AGRYPNINAE
Subfamily PROSTERNINAE
Notes:
1 Ampedus: Ectamenogonus sometimes used for those species with bicarinate pronotal hind angles
2 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 (eg, Ctenicera horni)
Size
1-60 mm(2)
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)

Helpful image galleries include (6)(7)(8)(9)
Range
worldwide and throughout NA(2)
Habitat
Found in all but aquatic and the most severe arctic and alpine habitats(2): 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.
