Pterostichus algidus is a species of woodland ground beetle in the family Carabidae. It is found in North America.
Diet.
It has been observed that "P. algidus" is a consumer of Douglas-fir seed in the Pacific Northwest. Furthermore, it has been hypothesized that there is competition for food between "P. algidus" and another beetle, "Nebria brevicollis." The beetle "N. brevicollis" is of the same order as "P. algidus". Given similar preference size for prey, researchers have hypothesized competition between these two species.
