Alocerus moesiacus, a widespread but relatively sparsely collected Mediterranean species occuring from the Iberian Peninsula to Iran, was described from Kazanlak environs (Stara Zagora province, Bulgaria) as Callidium moesiacum by Imre Frivaldszky in 1837 [✱]. A. moesiacus is broadly polyphagous species developing in various decidous trees (Populus, Ficus, Ulmus, Platanus, Quercus etc.). Its larvae infest dead parts of living trunks and feed in the wood that has contact with the living tissue. Development reported also in dead branches. Life cycle is 2 or 3 years. Adults, active from late May to early September, are nocturnal and can be attracted by light.

Body length:9 - 20 mm
Life cycle:2 and more year
Adults in:May - September
Host plant:larvae feed in various deciduous trees (Populus, Ficus, Ulmus, Platanus, Quercus etc.)
Distribution: Bosnia and Herzegovina, Bulgaria, Crete, Croatia, Cyprus, Greece, Italy, Macedonia, Montenegro, Portugal, Spain, Iran, Iraq, Israel, Jordan, Lebanon, Syria, Turkey, Algeria, Morocco, Tunisia
