scientific name    Myrmica fracticornis    

Usually favor cooler moister environments such as ravines or montane areas. In Alberta M. fracticornis is found in a wide range of habitats, from the southern prairies, to the mountains and foothills (Wheeler and Wheeler, 1963, Creighton, 1950).

Found foraging from May until late September or early October, but is dependent on local temperatures, and become active in their nest by around March.

Workers are ~4.0-6.0 mm in length with a brown dull head, shiny gaster and a lighter thorax. Antennae are heavily bent (close to 90 degrees) and have a rounded lamina on the scape. The postpetiole’s ventral surface is convex in profile (Wheeler and Wheeler, 1963 and Creighton, 1950).

life history
Not much known. Nuptial flights take place in late August and pupae do not produce cocoons.

Not of concern.

diet info
Like most Myrmica species, M. fracticornis is omnivorous.
