Blabinotus spinicollis is a nocturnal species endemic to Canary Islands and Madeira. Larvae of this beetle mainly develop in
Laurus azorica but other broadleaved tree species have also been reported to serve as hosts
(Salix, Persea indica and
Apollonias barbujana).
The species is a typical inhabitant of humid laurisilva forests and is strictly confined to such habitats.
Females oviposit into recently dead shoots of Laurus azorica situated in fairly shady locations. Typically the diameter of such shoot is 5 -10 cm. Up to
several larvae can develop in one dead shoot. Only rarely branches within canopy or other sun exposed tree parts are attacked. Young larvae first feed
subcortically creating rather broad galleries filled with nonfibrous frass. Later instar larvae enter sapwood and create pupal cells there. Adults
hatch in December but do not leave the pupal cells before February.
Body length: | 9 - 15 mm |

The depicted beetle was reared from a dead branch of Laurus azorica collected in Hermigua (La Gomera, Canary Islands).
