Populations of ants in a low field
Populations of ants of a low field in southern Michigan were studied and 28 species were found in an area of 870 square yards which hordered a marsh. Abundance of colonies was determined by digging 40 yard-square plots.Brachymyrmex depilis andPonera coarctata pennsylvanica were widely distributed and had the greatest number of colonies but the yellowLasius seemed the most typical of the habitat.Lasius flavus formed large colonies, widely spread just beneath the soil whileL. minutus andL. speculiventris built mounds. The genusDolichoderus was also typical of the habitat. Three of the 4 North American species nested on the study area, while the fourth occurred nearby.
Flights of theLasius species, which took place in the late afternoon of August and September were abundant and conspicuous.
