✦ Synopsis

One hundred and fifty one colonies of the ant L. acervorum comprising 815 queens were sampled in dry pine forest at nine sites in SE Sweden. 63°70 of the colonies contained more than one queen and of these 79% had more than one egg-laying (functional) queen, i.e. were polygynous. By using the electrophoretic variation at the PG1 locus a high overall relatedness (0.4) among queens from the same colony was found indicating that young queens are adopted by their mother nest. No spatial microdifferentiation in allele frequencies could be detected and it thus seems that despite restricted movements of queens there is a free gene flow in the populations.
