Myrmica scabrinodis

Identification
Yellow red to blackish brown according to habitat. The antennal scape is sharply angled and sinuate near the base, often with a slight lateral extension in the larger more deeply sculptured forms. The petiole has a distinctly concave anterior face which meets the truncate dorsal surface at a sharp angle. Head Index: 85.6; Frons Index: 36.8; Frontal Laminae Index: 66.5. Length: 4.0-5.0 mm. (Collingwood 1979)

Biology
Collingwood (1979) - The species has variable habits, being found in a very wide range of habitats. In southern areas it is often associated with the meadow ant Lasius flavus (Fabr.) living in part of the mound nest and preying on the L. flavus workers but may be equally common in woodland, coastal sand, gravel river banks, peat bogs and moorland. Individual nests are small, situated under stones, in tree stumps or in the ground with a few hundred workers and one or a few queens. The alatae fly in August, pairing occurring in the air.
