Explanation of Names
Latin galeritus 'wearing fur hat'
8 spp. in our area (all but G. aequinoctialis
in the subg. Progaleritina
(ca. 90 spp. worldwide)
Compare head shapes of G. bicolor vs. G. janus:
key to the three SC spp. in(2)
worldwide except the Australian region, but not far north (and only in the Pacific part of the Palearctic); in NA, transcontinental in the south and along the Mississippi Basin north to MB in the west and MA in the east; G. bicolor
and G. janus
are widespread eastern species; G. lecontei
is found in so. and sw. US (the only sp. ranging into CA) and Mexico(1)
Open woodlands, under stones, leaves. Come to lights, sometimes wander into houses.
Much of year in south. In SC, G. bicolor Feb-Dec, G. janus Apr-Dec, G. lecontei Apr-Aug + Nov
Adults eat other insects, especially caterpillars(3)
Eggs are deposited in a purse-shaped mud cell on the underside of smooth leaves; this behavior + the distinctive larva suggest an unusual way of life(1)
These beetles have chemical defenses (see Rossini et al. 1997
in NC, G. janus
is common in the mountains and G. bicolor
occurs mostly at lower elevations(4)
