Pterostichus algidus is a species of woodland ground beetle in the family Carabidae. It is found in North America. [1] [2] [3] [4]
It has been observed that P. algidus is a consumer of Douglas-fir seed in the Pacific Northwest. [5] 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. [6]
Nebria brevicollis, belonging to the Carabidae family, is a ground beetle. With nearly 500 species and over 100 subspecies, N. brevicollis is the most diverse genus within the Nebriini tribe of ground beetles. Members of the genus occupy a wide range of habitats. Nebria brevicollis is native to Europe and the Near East but has been introduced to the western United States and Canada. Its rapid expansion in North America is characteristic of an invasive species. Due to the variation in habitat, their diet consists of small arthropods including Collembola, Diptera, earthworms, mites, and spiders.
