Coproporus ventriculus
(Say, 1832)
Coproporus is a of in the , Tachyporinae. It belongs to a associated with decaying matter and fungal . The species has a broad North distribution spanning much of Canada and the United States. Like other members of Tachyporinae, it is likely associated with rotting substrates where it feeds on fungal spores and , though specific ecological studies on this species are limited.

Identification
Members of the Coproporus can be distinguished from similar Tachyporinae by their compact, somewhat convex body form and the structure of the mouthparts adapted for . Within the genus, C. is recognized by its relatively broad, ventricose (swollen) , which gives the its specific epithet. Accurate identification to species level typically requires examination of male and comparison with related species such as C. ventricosus and C. fimbriatus.
Habitat
Associated with decaying matter, particularly rotting wood, leaf litter, and other substrates supporting fungal growth. Found in forested and semi-open environments where moisture and decomposition create suitable microhabitats.
Distribution
Widespread across northern North America. Recorded from all Canadian provinces and territories except Nunavut, and throughout much of the contiguous United States from the Atlantic coast to the Pacific coast, including Alaska. Absent or unrecorded from Hawaii and the southernmost tier of U.S. states.
Ecological Role
As a member of the , contributes to in decaying matter systems. Consumes fungal material, potentially influencing fungal structure and spore in forest floor and dead wood .
