Genus Schizophilus

False Click Beetle - Schizophilus subrufus Schizophilus subrufus Schizophilus subrufus Schizophilus subrufus Schizophilus subrufus Schizophilus subrufus Elateridae - Schizophilus subrufus Elateridae - Schizophilus subrufus
Classification
Kingdom Animalia (Animals)
Phylum Arthropoda (Arthropods)
Subphylum Hexapoda (Hexapods)
Class Insecta (Insects)
Order Coleoptera (Beetles)
Suborder Polyphaga (Water, Rove, Scarab, Long-horned, Leaf and Snout Beetles)
No Taxon (Series Elateriformia)
Superfamily Elateroidea (Click, Firefly and Soldier Beetles)
Family Eucnemidae (False Click Beetles)
Genus Schizophilus
Numbers
One Nearctic species, N. of Mexico.
Size
7.5-12 mm long.
Identification
Protibiae with 2 apical spurs, setose claws and trilobed clypeus are distinctive features to identify the group.
Range
Widely distributed throughout Eastern U.S.
Habitat
Largely found in forested areas. The group can be found in a variety of forest community types.
Season
May through the end of August.
Food
Larvae were found in oaks, maples and beech.
Life Cycle
Development take about one year, but it may arrest its development by an extra year until suitable conditions are met. Larvae were collected in rotten wood, close to the soil.
Remarks
The highly unusual larval type was described by Otto and Young in 1998.

The genus is closely related to Pseudomenes of southeastern Australia and Tasmania.
See Also
Schizophilus is easily confused with the elaterid genus, Melanotus. These groups can be separated by examining their tarsal claws (serrate in Melanotus, simple in Schizophilus) and the placement of the 2nd antennomere to the basal segment (terminal in Melanotus, subterminal in Schizophilus).
