, as the beetle has a thick coat of hairs (1)
Yellow/brown elytra marked with black, lots of yellowish hairs on thorax. Probably mimic of bumblebees, it has buzzy flight.
An uncommon dark form was previously considered a separate subspecies, E. inda nigripennis (3)
AZ-FL-ME-WA / BC-QC / Mex (4)
Adults emerge in the late summer, overwinter, and then become active in the early spring, which accounts for the bimodal curve in adult activity. (2)
Adults visit flowers for pollen and/or nectar. Sometimes damage flowers. Also takes rotting fruit, corn, sap, other plant juices.
Larvae usually reported to live in decaying wood, vegetation, and especially, dung (5)
. Eggs deposited in summer near these food sources. Males often seen searching for newly-emerged females.
Larvae are associated with Formica
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.

), gives this account:
Throughout the State (Indiana); frequent. March 20-August 17. On the first warm, sunny days of spring this "bumble flower-beetle" comes forth in numbers and flies close to the ground with a loud buzzing noise like that of a bumble-bee, for which it is often mistaken. When captured it defends itself by emitting a strong, pungent chlorine-like odor. A second brood is said to appear in September. The larva live in rotten wood, beneath chips and other woody debris. The adults are often found sucking the juices of roasting ears, peaches, grapes and apples, and sometimes do much damage.
