| Aphaenogaster cecconii|
Aphaenogaster cecconii is a common species in Crete. The nest entrances are found in small caverns, at entries to large caves, cracks in rock walls of northern exposure, inside large porous limestone rocks in shady places of mountain streams, in ancient tombs, and in walls of ruins and other man-made structures. The ants forage in an area 70–100 cm around the entrance to the nest. In three cases we observed single workers crawling over large rocks in streams, likely transported there by the current after heavy rains. The workers bring small plant seeds or pieces of stalks to the nest, but also small fragments of dead insects. When disturbed, the ants retreat swiftly into the nest entrance, remain immobile, or fall from the rock wall or stone onto the ground. We have not conducted any night observations so it is hard for us to say whether the species is more active at night. During the day we did not see any peaks of high activity. Even during the heat of the day their habitats are shaded and workers forage in the area around the nest. (Borowiec and Salata 2014)
Borowiec and Salata (2014) - Aphaenogaster cecconii is the species with the most elongated body, constricted neck base and head sides straight posterior to the eyes. It is also the darkest-colored species, mostly dark brown to black and only the first gastral tergite has a pale, whitish to whitish-yellow spot. The only other Mediterranean species that is dark colored and possesses a distinct neck constriction, Aphaenogaster lykiaensis, differs in the body being brown to partly rusty brown, the first gastral tergite uniformly brown, the head constriction broader, and the sides of the head posterior to the eyes slightly bulging. The third dark species, Aphaenogaster jolantae, distinctly differs in having an elongately-oval head without a pronounced neck constriction, and the first gastral tergite is uniformly dark brown.
