Populations of ants in a low field

  • Mary Talbot
Article

Summary

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.

Résumé

On étudia les populations de fourmis qui habitaient un champ d'altitude basse dans le sud de l'état de Michigan. On en trouva 28 espèces dans une étendue de 727 m2 qui bordait un marais. On détermina l'abondance des colonies en creusant de petits terrains carrés de 36,5 mètres de chaque côté.Brachymyrmex depilis etPonera coarctata pennsylvanica étaient largement distribués et avaient le plus grand nombre de colonies, mais leLasius jaune semblait être l'espèce la plus typique de l'habitat.Lasius flavus formait de grandes colonies, largement étendues juste au-dessous du sol, tandis queL. minutus etL. speculiventris construisaient des tas. Le genreDolichoderus était également typique de l'habitat. Trois sur les quatre espèces nordaméricaines nichaient sur le terrain étudié tandis que la quatrième nichait tout près.

Les vols de l'espéceLasius, qui avaient lieu tard dans l'après-midi aux mois d'août et de septembre, étaient abondants et bien visibles.
