Glischrochilus sanguinolentus
(Olivier, 1790)
Bloody Sap Beetle
Glischrochilus sanguinolentus, commonly known as the Bloody Sap Beetle, is a of sap-feeding beetle in the Nitidulidae. It is native to North America and belongs to a known for association with fermenting plant sap, fungi, and occasionally damaged fruit. The species is relatively well-documented with over 700 observations on iNaturalist.

Identification
The "sanguinolentus" (meaning bloody or blood-red) suggests reddish coloration, likely distinguishing it from . Glischrochilus generally have compact, oval bodies with short that may expose part of the . Precise identification requires examination of subtle morphological features such as elytral color pattern, punctation , and genitalia structure.

Habitat
Associated with environments where sap flows, fungal growth, or fermenting plant material occurs. This includes wounded trees, decaying wood, and areas with fungal fruiting bodies.
Distribution
North America; specifically recorded from Vermont and broadly across the continent.
Diet
Feeds on sap flows, fungi, and fermenting plant material. The specific dietary preferences for this have not been separately documented from .
Ecological Role
Acts as a decomposer, facilitating nutrient cycling through consumption of fermenting plant material and fungi. May contribute to spore of associated fungi.
Human Relevance
May be attracted to damaged or overripe fruit in agricultural settings, though specific pest status for this is not documented. The "Bloody Sap Beetle" reflects its appearance rather than any medical significance.
Similar Taxa
