Plesiobiosis, interactions, commensalism, mixtobiosis, mixed colonies


Three compound nests of Formica lemani Bondroit, 1917 and Lasius flavus (Fabricius, 1782) are reported from Lygra, Western Norway. This is the first plesiobiontic relationship reported for F. lemani and the 9th for L. flavus. Behavioural and landscape ecological traits associated with plesiobiosis are discussed.
