Species Fact Sheet
Carpophilus antiquus Melsheimer, 1844
Figure 1. Male dorsal and ventral habitus
Diagnosis: Carpophilus antiquus specimens are distinguished from other eastern North American species by having the following combination of features: elytra with darker coloration near the apex only (Fig. 1 & 7), and an impunctate area near the center of the mesosternum (Fig. 3). The male metathoracic tibia is abruptly dilated apically (Fig. 5 & 6).
Distribution: Carpophilus antiquus is found in eastern North America from Quebec to Florida and west to Wisconsin, Iowa, Kansas, and Texas.
Biology: C. antiquus is most commonly associated with corn (Bartelt, Seaton, and Dowd 1993). It has also been collected fallen peaches, rotting melon, under Quercus sp. woodchips, under the bark of Pinus sp., in traps with banana and fermenting brown sugar, and other rotting fruit (Connell 1956; Price and Young 2006) Larvae illustrated and described by Connell (1956).
