Collingwood (1979) - It is normally a woodland bark-inhabiting species but occasionally nests under stones or inside acorns. Its morphology and biology in France where it is common, has been intensively studied by Plateaux (1970). The species is normally monogynous with between 100 and 200 workers. Is is somewhat more aggressive than Leptothorax acervorum and despite its small size will attack and sting freely. Alate queens and males are developed during July and flights occur during early August.

Identification

Csösz et al. (2015) - A member of the nylanderi species-complex. Temnothorax nylanderi has moderately long spines (SPST/CS) and therefore cannot be confused with long-spined Temnothorax lichtensteini. Non-overlapping SPBA/CS ratios help to distinguish it from T. flavicornis. Based on salient features, T. nylanderi might be misidentified as Temnothorax parvulus, but a simple ratio (SPTI/CS) reliably separate these species on the level of nest sample means. Temnothorax nylanderi can also be safely separated from weakly sculptured, lightly colored Temnothorax tergestinus using the ratios PoOC/CL and SPWI/CS.

Collingwood (1979) - Yellow to pale yellowish brown, the head sometimes darker, broadly infuscate on the first gaster segment. Antennae including clubs and legs concolorous with the rest of the body. Head longitudinally striate. alitrunk finely rugose, gaster smooth. Legs without erect hairs. Antennae twelve segmented; mesopropodeal impression distinct and clearly visible in side view. Length: 2.3-3.4 mm. This species is immediately distinguishable from all other North European Leptothorax with twelve segmented antennae in the worker caste by the distinct mesopropodeal suture seen as a clear depression in the dorsal profile.

Biology

Fungi

This species is a host for the endoparastic fungus Myrmicinosporidium durum (Espadaler & Santamaria, 2012).

Castes

A feature of T. nylanderi is the study of rare morphological anomalies that are intermediate between the queen and worker phenotypes (Plateaux 1970). A large number of such "intercastes" were investigated with multivariate morphometry (Okada et al. 2013), showing how caste-specific modules (i.e. specific to workers and winged queens) are shuffled to give a mosaic phenotype (intercastes).
