Formica cinerea

This species characteristically occurs in drift sand on coastal dunes in North Europe but also locally inland on coarse morainic drift, and in sandy soils with sparse plant cover in Russia (Zryanin & Zryanina, 2007). It is an aggressive species living largely by predation. Nests may be founded by single queens but where the species is populous, colonies are frequently polygynous and polycalic. Alatae occur in July (Collingwood, 1979). Its ecology and distribution in Finland are described by Kilpäinen. Valkeila, Vesajoki and Wuorenrinna (1977). In the Rhône valley in Switzerland it hybridizes with Formica selysi, where they form a mosaic hybrid zone, with limited introgression from F. selysi into F. cinerea (Blacher et al., 2022).

Identification
Seifert (2002) - A member of the Formica cinerea group.

Distribution
Seifert (2002) - Formica cinerea is the only species of the group with a very extended distributional range stretching from N Spain to W Siberia (Tjumen, 65.28 E, 57.09 N; Bamaul, 83.45 E, 53.20 N; Bijsk 85.10 E, 52.32 N; Dlussky, 1967) and from S Greece north to Finland at 65 °N. Within this huge range, only weak geographic variation exists - with the exception of a steeply positive gradient of genal pilosity from Central Europe to the Central Balkans. In the Pyrenees, the Alps and the Caucasus the overall abundance of F. cinerea is clearly decreased by the competitive pressure of Formica selysi, Formica fuscocinerea, or Formica georgica. No observations of F. cinerea are known so far from the British Isles. F. cinerea is apparently the only species of the group occurring in Czechia, Poland, and the steppes of S. Russia.

Biology
Ślipiński et al. 2015 (abstract): The abiotic conditions of the desert habitat fluctuate in a circadian rhythm of hot days and cold nights. Species living in desert habitats evolved many adaptations to increase their chances of survival. However, abiotic conditions in xerothermic habitats of a temperate climate are much different. Diurnal fluctuations are not as strong, but animals have to cope with seasonal changes and hibernate during the winter, which may potentially influence their adaptations to critical temperature conditions. We attempted to assess heat resistance adaptations using the example of a widely distributed xerothermic ant Formica cinerea. Using Real-Time PCR, we measured the expression of three heat shock protein genes (Hsp60, Hsp75, Hsp90) and assessed the adaptations of F. cinerea to enable foraging in risk prone conditions. The analysis of gene expression using the Generalized Linear Model surprisingly indicated that there was no significant effect of temperature when comparing workers from the control (23ºC) with workers foraging on the surface of hot sand (47-54ºC). As a next step we tried to estimate the threshold of a thermal resistance with the use of thermal chambers. Expression of all Hsps genes increase compare to the control group, expression of Hsp60 and Hsp90 continued up to 45ºC.

Milar et al. (2017) found in an experimental test, simulating being threatened with entrapment in sand (as might happen if falling in an ant lion pit or if subjected to a collapse of a ground nest), that this species did exhibit rescue behaviour. This was in agreement with their hypothesis that species that could face entrapment situations would show such a response. Formica cinerea nests in sandy soils.

Other Organisms


The reported host/parasite relationships between Formica aquilonia and Formica lugubris and Formica cinerea should be investigated in the field as Chernenko et al. (2013) found 100% F. aquilonia and Formica lugubris queen mortality in lab introductions (de la Mora et al., 2021).

The records of this species being enslaved by Formica aserva noted by Ruano et al. (2019) are in error as this species is outside the geographic distribution of F. aserva (Palearctic host, Nearctic parasite) (de la Mora et al., 2021).

Lateral mesonotum anterior of meta thoracic spiracle densely microcarinulate, with an mean carinular crest distance of 4- 5 mm; mean width of carinulae equal or slightly smaller than width of smooth inters paces. Transition between dorsal and caudal profiles of propodeum in larger workers broadly convex, in smaller workers more angular and under an angle of 140°. Dorsal crest of petiole in frontal view usually convex, in larger specimens frequently forming a blunt angle of 140°. Petiole scale in lateral aspect rather thick, wedge-shaped, with convex anterior and rather straight posterior profile. Head, mesosoma, petiole, and gaster covered by a dense silvery pubescence, PDG 6.3 - 7.5. Colour polymorphism.
