Icosium tomentosum is a circummediterranean species represented by two distinct subspecies: tomentosum Lucas, 1854 and atticum Ganglbauer, 1881. Atticum is mainly an East Mediterranean subspecies occurring in Turkey, Balcan Peninsula and reaching South France in the West. The nominotypical subspecies occurs in South-West Europe and Maghreb. Both subspecies develop in various Cupressaceae (Juniperus, Cupressus, Thuja, Callitrix, Tetraclinis, etc.). Larvae first feed under bark and later enter the wood of recently dead or moribund hosts. The adults, active from June to August, are nocturnal and frequently come to light [✳][✧].
Icosium tomentosum has been described from Oum Drou environs (Algeria) by Pierre Hippolyte Lucas in 1854 [❖].
Body length: 8 - 15 mm Life cycle: 2 years Adults in: June - August Host plant: oligophagous in various Cupressaceae Distribution: South-West Europe (Corsica, France, Italy, Sardinia, Spain) and North Africa (Algeria, Morocco, Tunisia)
The depicted beetles were reared from larvae collected in dying Juniperus oxycedrus in Tanafnit village (Khénifra province, Béni Mellal-Khénifra region, Morocco) on May 16, 2022.Collected by Petr Jelínek
