Carpophilus brachypterus (Say, 1825)
Figure 1. Male dorsal and ventral habitus
Diagnosis: Carpophilus brachypterus specimens are distinguished from other eastern North American species by having the following combination of features: body convexity flattened (fig. 2), antennomere coloration unicolorous throughout antenna, ratio of eye width at widest point in dorsal view to intraocular distance at narrowest point between 1:4 and 1:9, pronotum posterior angles broadly rounded with no distinct ‘corner’ created, and posterior rim of mesocoxal cavities smooth, not forming axillary space.
Distribution: Carpophilus brachypterus is found in eastern North America from Nova Scotia to North Carolina and west from Manitoba to Kansas.
Biology: Collected from a variety of flowers, stored grains, recently cut hardwoods, and decaying fruit (Pellitteri and Boush 1983; Bousquet 1990; Price and Young 2006).
