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 (1), Central and South America
See Numbers above
Habitat
Fields, meadows, thickets
Season
Early Summer (April-July), some species into October (NC)
Food
Adults visit flowers (for pollen and/or nectar) and rotting fruit
Life Cycle
Larvae usually reported to live in decaying wood, vegetation, dung. Eggs deposited in summer near these food sources. Larvae feed and overwinter, or perhaps pupae overwinter. Adults emerge in early summer. Males often seen searching for newly-emerged females. Larvae may be associated with ants. "Larvae of these species are reported to live in decaying wood, but I suspect that some 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) published the most thorough treatment to date for S. thoracica Casey (recently synonymized with S. areata (F.) by Harpootlian 2001). Skelley located larvae in the mounds of the pocket gopher, Geomys pinetus, in Florida and was the first to describe an immature stage for the genus. Published accounts of Stephanucha species biology are consistent with respect to spring emergence, presence in sandy habitats, and a potential lack of adult feeding or liquid feeding (Lago et al. 1979; Skelley 1991). Skelley (1991) suggested that the main habitat of Stephanucha spp. might be pocket gopher mounds. He noted sympatric distributions of Stephanucha spp. with pocket gophers, including S. pilipennis. Kraatz found in the range of G. bursarius (Shaw). However, he noted that the larvae he observed were nonspecific in habitat requirements, also utilizing mounds in sandy soil created by other organisms or processes. (Paulsen 2002) Now considered a synonym of Euphoria(3)
