Camponotus piceus

This species is mainly distributed in southern and central Europe and in the southern part of eastern Europe, but it is also present in north-west Africa, Asia Minor, Lebanon, Iran, the Caucasus, and northern Kazakshtan (Czechowski et al. 2002). It is a xerothermophilous species living mostly in open, dry grasslands, and is ground-nesting. Workers are highly polymorphic (Marko et al., 2009; Rigato & Toni, 2011).

Distribution
Marko et al. (2009) - It is present throughout Romania. The occurrence of C. piceus sp. 2 (Seifert 2007) can also be expected, based on preliminary distribution data.
