Species Fact Sheet
Carpophilus marginatus Erichson, 1843
Diagnosis: Carpophilus marginatus specimens are distinguished from other eastern North American species by having the following combination of features: length measured from mandibles to abdominal apex 1.8-2.6 mm, antennomere coloration unicolorous throughout antennae (Fig. 2), pronotum posterior angle nearly forming a 90 degree angle (Fig. 3), and the posterior rim of the mesocoxal cavities smooth forming an axillary space extending approimatly 1/4 to 1/2 down the metepisternal suture. Males also have two distinctly longer setae on their supplementary segment (Fig. 4 & 5).
Distribution: Carpophilus marginatus is found in eastern North America from New York to Florida and west from Michigan to Alabama. It has also been recorded in Oregon, Louisiana, Costa Rica, and Guatemala.
Biology: Very little is known about the biology of C. marginatus. It has been collected from oak sap flows, freshly-cut oak, and southern red oak (Vogt 1950; Williams et al. 1997; Gil, 2008). Also collected from figs (Riley and Howard 1889).
