Species sepulcralis (Dark Flower Scarab)
Other Common Names Spangled Flower Beetle
Explanation of Names Common name proposed here, "spangled" is a coinage, based on white marks scattered on dark elytra. "Dark Flower Scarab" is also an appropriate common name.
Species name sepulcralis is Latin, meaning Of or relating to a sepulchre (tomb); "sepulchral inscriptions";. Refers, perhaps, to dark coloration and/or white markings? (Based on Internet searches.)

Euphoria sepulcralis rufina (Gory and Percheron, 1833)
Euphoria sepulcralis sepulcralis (Fabricius, 1801)
Identification Very dark elytra with scattered light spots. Variable, some individuals have weak spotting and have rusty hairs on elytra. Found on flowers.
Range Eastern and southwestern United States
Habitat Usually fields with flowers
Season April-June, August-September (South Carolina), May-September (Indiana), listed April-July for North Carolina by Brimley (1).
Food Adults appear on foliage of late spring flowers, such as Marshallia, so presumably take pollen and nectar. In Texas, reported to feed on twig of Blackjack Oak, Quercus marilandica.
Eggs are laid in soil under organic matter or manure, and this is where grubs develop.
Life Cycle Spring and late-summer occurrence suggests two generations per year, or that adults overwinter, perhaps.
Remarks Blatchley, p. 997 (2), ( direct link), says:
Throughout the State (Indiana); frequent. May 6-September 30. Occurs at sap, also on flowers of various kinds, especially goldenrod (Solidago) in autumn. Sluggish and feigns death when touched.
See Also Euphoria inda has an uncommon dark form, which might be mistaken for E. sepulcralis.
