Size

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/ventral views of E. fulgida, E. herbacea, E. inda, E. sepulcralis
Range
across NA and the New World(1)
Habitat
Fields, meadows, thickets
Season
Apr-Jul, some species into Oct in NC
Food
Adults visit flowers (for pollen and/or nectar) and rotting fruit, larvae feed on organic matter in soil
Life Cycle
Larvae usually in decaying wood, vegetation, dung. Eggs deposited in summer near these food sources. Larvae, or perhaps pupae, overwinter. Adults emerge in early summer. Males often seen searching for newly-emerged females. Larvae may be associated with ants and live as scavengers in ant nests (primarily those of Formica obscuripes). "E. inda [...] is commonly seen buzzing over Formica mounds in spring. On descending to the mound it is immediately covered by ants. E. fulgida [...] is much less common and is generally found at Prunus or Amelanchier blooms in the spring." (Insects of Cedar Creek)
Remarks
Skelley (1991) located E. areata (=S. thoracica) larvae in the mounds of the pocket gopher, Geomys pinetus. Published accounts are consistent with respect to spring emergence, presence in sandy habitats, and a potential lack of adult feeding or liquid feeding in this genus (Lago et al. 1979; Skelley 1991).(2)
