The drab Enoclerus moestus can be found on freshly dead pine in early summer at high elevations of the sky islands. It hunts for insects that come to lay their eggs in the wood.
Enoclerus bimaculatus and E. luscus often appear at the black light in upper Madera Canyon. Dried specimens of E.bimaculatus have strikingly pink markings, but on the living beetles they are ivory colored.
Both color morphs of Enoclerus laetus can be seen together on blooming Baccharis in autumn. While larvae and adult beetles of the genus Enoclerus usually feed on other insects, some of them also like protein rich pollen.
With 36 species north of Mexico, Enoclerus is the species richest genus of the family Cleridae in the US. While the genus ranges across the entire American continent, most species occur further south in Central and South America and it is assumed that their phylogenetic origin is located there.
Even though the beetles are small and quickly fly when disturbed, I have found and photographed several more species here in Arizona. Twice I have been extraordinary lucky: In 2009 I 'rediscovered' Enoclerus decussatus in Sycamore Canyon at my black light.
