Carpophilus marginatus
Erichson, 1843
Carpophilus marginatus is a of sap-feeding beetle in the Nitidulidae, described by Erichson in 1843. It belongs to a whose members are commonly associated with fermenting plant materials and overripe fruit. The species is recorded from North America, though detailed ecological and biological information remains limited. Like other Carpophilus species, it is presumed to exploit sugary substrates, but species-specific and associations have not been well documented.

Identification
Identification to level within the Carpophilus typically requires examination of subtle morphological characters including antennal club structure, pronotal shape, and elytral punctuation patterns. C. marginatus can be distinguished from such as C. hemipterus and C. truncatus by specific arrangements of these features, though definitive identification may require reference to original species descriptions or keys.
Distribution
North America. Specific locality records are sparse, with the documented from the continent based on collection data and taxonomic literature.
Ecological Role
As a member of Nitidulidae, likely contributes to decomposition of fermenting plant materials and nutrient cycling, though -specific ecological functions have not been documented.
