Bolivarita oculata, an endemic species to Morocco, has ben described from As-Sawíra (Mogador) environs by Manuel Martínez de la Escalera in 1914 [✧]. Biology and larva of this very interesting and not so often collected nocturnal species were in detail described by Gianfarnco Sama in 1987 [✳]. Larvae of B. oculata develop in dying or dead thin branches (10-25 mm in diameter) of argan tree (Argania spinosa). The larvae create a relatively long (30 - 40 cm) and excrement/sawdust free gallery in the middle of the infested branches. Larval development lasts at least two years, the pupation takes place at the end of July at the end of the gallery blocked by a simple sawdust plug. Hatching, which begins in mid-August, continues until the end of September. Adults are nocturnal and are often attracted to light. The adults, sitting motionless on the twigs of the host tree during the day, are very active at night and fly away immediately when disturbed. [✳].

Body length:7 - 9 mm
Life cycle:at least 2 years
Adults in:August - September
Host plant:monophagous in Argania spinosa
Distribution:an endemic species to Morocco

The depicted living beetles were reared from larvae found in dying Argania spinosa twigs in Aourir ( ⴰⵡⵔⵉⵔ) environs (Agadir-Ida Ou Tanane province, Souss-Massa region, Morocco) on May 28, 2022.
