Hoplia debilis LeConte
6-8 mm
Black with sparse white hairs. Similar to H. trifasciata
e. US south to GA and west to IL & TX(1)
on vegetation/flowers, young pines, hickories; under boards, rocks, near water
March-May, sometimes June, July (Carolinas).
Life Cycle
Described for Hoplia callipyge: Larva is C-shaped grub, feeds on roots of forbs, grasses. Overwinters as late-stage larva. Pupates in soil in spring.

In Durham North Carolina, seen in spring (April) climbing stems of grasses (Broomsedge, Andropogon) in old field habitat, adjacent to mixed pine deciduous woods. These (males?) spread antennal plates and then flew off, perhaps searching for females.
