Geographic Range [top]

Range Description:This species occurs in the Circum-Mediterranean (Bense 1995) and in some countries of central Europe.

It is also found in northern Africa, all Caucasus, Minor Asia, Turkey and Iran.

In Portugal it has been recorded across the whole country, but from few localities and mostly before 1951. In Romania there are new records that report this species from Dobroudjia, on the Black Sea coast. It is widespread in Cyprus. Occasional occurrence recorded in the Czech Republic but probably from introductions.
Countries occurrence:
Bulgaria; Croatia; Cyprus; France (Corsica, France (mainland)); Greece (Greece (mainland), Kriti); Italy (Italy (mainland), Sardegna, Sicilia); Macedonia, the former Yugoslav Republic of; Malta; Montenegro; Portugal (Portugal (mainland)); Romania; Serbia (Kosovo, Serbia); Spain (Baleares, Spain (mainland)); Ukraine (Krym, Ukraine (main part))

Population [top]


There is little information available on the abundance of this species but reports suggest that it is plentiful in many countries. In Cyprus and Greece this species is common whlie in Italy it is not uncommon. In France it is common in the Mediterranean border (Villiers 1978). In Ukraine it is relatively rare. In Romania there are few new reports, and it is believed that there are only small populations (P. Istrate pers. comm. 2009).

Habitat and Ecology [top]

Habitat and Ecology:This is an obligate saproxylic species. Larval development occurs in both living and dead tress, feeding first under the bark, then boring into the dead parts where in contact with living tissues or directly into living tissues with sap circulation. Found on a wide variety of host trees, eg Quercus, Fagus, Prunus, Pistacea, Acacia. In Romania it is known from Sambucus nigra, Ruber nigra, and Quercus. In Cyprus it has been reared from dead wood of Ficus carica (C. Makris pers. comm. 2009). The stage of pupa is three weeks. The life cycle is usually one year, but sometimes more. Adults active in VI-VIII, crepuscular or nocturnal, often attracted to light (Sama 2002). 

In Greece this species is considered a vector for a fungus disease that destroys Castanea sativa.

In Cyprus it has been found in orchards, maquis, garigue, forests, villages and towns (C. Makris pers. comm. 2009).

Use and Trade [top]

Use and Trade: Saproxylic Coleoptera tend to be popular with beetle collectors although trade is rarely an issue, the only exceptions being a few larger species of more dramatic form or colour.

Threats [top]

Major Threat(s):

There appears to be no major threats to this species. The replacement of native shrubs from warm places in the Balkan region can be a threat to this species.
