Messor creticus

An Alpine species recorded only form areas located above 1000 m. Nesting in soil, most often in humid, open areas, e.g., pastures or fields. Workers most active at nightfall, collecting seeds from ground or herbs. Colonies monogynous.

Identification
Messor creticus is most similar to Messor caducus and is easily distinguished from most of Mediterranean Messor in having mostly smooth and shiny head surface, more than 10 thick, erect setae on promesonotal dorsum, sparse and short erect setae on the first gastral tergite and presence of additional reticulation between striae covering surface of mesosoma. From M. caducus, it differs in lack of distinct psammophores. M. creticus has ventral head surface covered with long, thin setae that are only slightly curved on their upper part and do not form a shape characteristic for psammophores.
