Description
Lasius emarginatus is a small ant, reaching a length of 3-5.5 mm in the workers, 7–10 mm in the females and 7-14.5 mm in males. In workers and females the thorax is reddish or brownish-red, while the head and the abdomen are brown. Males are completely brown.
The longevity of the queen reaches up to 30 years, but for workers it is limited to 3 years. The species is omnivore. Colonies are monogynous (one queen per colony). They are not aggressive but they do not mind attacking a potential predator or another colony to expand their hunting and harvesting territory.
Distribution
This species is present in the Western Palearctic ecozone (Europe, the Caucasus, Asia Minor).
Colony Founding
The nuptial flight happens between June and August. After the mating the queens normaly found their colony alone, but it is also possible that they found their colony in Pleometrose. After the first workers hatch one of the queens get killed.
