Habitat
Fields, meadows
Season
February-April, and August in South Carolina (3). Reported in May in Minnesota.
Food
Adults visit flowers for pollen and/or nectar. Sometimes damage flowers. Also takes rotting ruit, corn, sap, other plant juices.
Life Cycle
Larvae usually reported to live in decaying wood, vegetation, and especially, dung (4). 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 are, perhaps, associated with ants? From Insects of Cedar Creek:
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 (yellow with black flecks) is commonly seen buzzing over Formica mounds in spring. On descending to the mound it is immediately covered by ants.
