(1)Identification
Medium-sized, rather wide and flattened diurnal scarabs. Rather hairy underneath and on sides, giving them a cute, almost teddy-bear appearance. Flight is buzzy, like a bee or fly. Elytra apparently do not open in flight, which perhaps contributes to the buzzy sound--see this illustration of
E. fulgida. Seen on flowers or buzzing about forest floors and diving abruptly into leaf litter.
Most eastern species can be told apart at a glance by color pattern: see, from left to right, dorsal views of E. fulgida, E. herbacea, E. inda, E. sepulcralis
