Oxythyrea cinctella Schaum 1841

Rahes, Ikaria ● Greece

Description: The genus Oxythyrea includes 11 species of Europe and North Africa. It is characterized by a body of small size (6-13mm) black shining, sometimes bronzed, in general with white spots on the pronotum, the elytra, the pygidium and the abdominal sternites. These white spots can be some time absent or very developed.
The sexual dimorphism is often accentuated: the males have the posterior tibiae abruptly dilated at the inner apical angle and have extended white spots on the abdomen which is depressed in the middle whereas it is convex in the females.
In Oxythyrea cinctella, the pronotum is generally narrowly bordered of white with and 2 white ponctiformes spots close to the base.

Biology: The Oxythyrea species play an important ecological role because their larvae contribute to recycle the vegetable matters in decomposition, thus supporting their assimilation in the soil. The small larvae of 1,2-1,8mm live in the heap of plants in decomposition, especially at the main steam of the roots of the herbaceous plants. The imagos when too numerous, can damage some cultures (vineyard and cereals).

Distribution: O.cinctella has a wide distribution: from former Yugoslavia through southernmost Russia of the Caucasus, until Pakistan and the West Afghanistan. It populates also all the Greek islands of the Eastern Mediterranean. In Levant, it is observed of SE of Anatolia, Syria, Lebanon, Israel, Jordan, Iraq, Palestine and Egypt.
