A species associated with open, sunny and arid habitats with sandy soil. Nesting under stones or in soil. Very often located on dirty roads, seaside or in alpine zone. Monogynous colonies. Workers active during the day. (Salata & Borowiec, L., 2018)

Identification

Salata and Borowiec (2018) - Cataglyphis cretica is a member of the C. cursor group characterized by uniformly dark body colouration and nodiform scale. From most of Mediterranean species it differs in lack of erect setae on scape and presence of at most 3-5 erect setae on the occipital margin of head and first gaster tergite (in most specimens erect setae are absent). The only known species with similar set of characters is Cataglyphis aenescens. Workers and gynes of C. cretica differ from C. aenescens in bigger body size and dull body sculpture. There also distinct differences in male genitalia between those two species. In C. aenescens median appendix of squamula is big and has a shape of widening distally shovel, while C. cretica has median appendix of squamula small and spherical.

Queen

Queen is brachypterous, i.e. short, non-functional wings are present at adult emergence. This implies that she mates close to her natal colony, and dispersal distance is limited (Peeters & Aron 2017)

Lack of wing muscles inside the thorax of Cataglyphis cretica brachypterous queen. Compare this to a normal flying queen such as Cataglyphis viatica. Dissection by Christian Peeters, photograph by Adam Khalife.

Salata and Borowiec (2018) - Cataglyphis cretica, based on limited material, was synonymized with C. aenescens by Borowiec & Salata (2013). After re-examination of collected material, supplemented by further expeditions, and study on type specimens we discovered features that allow us to consider this taxon as a good species.
