Common name:
French name: Clyte poilu
Order: Coleoptera
Family: Cerambycidae

Chlorophorus glabromaculatus is a small black longhorn beetle whose body is covered by dense short greenish yellow hairs giving a velvet appearance.
The colour of the body appears thru small hairless spots forming six black spots on the elytra and two on the pronotum, these two last ones sometimes weekly marked or even missing.
The eyes are notched for the antennae.
There is a possible confusion with Chlorophorus glaucus which is found in North Africa, in the Iberian Peninsula and on the Balearic Islands, close to the Mediterranean coast in the south of France.
You can recognize females of this last species with their grey colour, while female Chlorophorus glabromaculatus are a greenish yellow colour similar to males.
Identification of males is much more difficult. Chlorophorus glaucus shows longer greenish yellow hairs on pronotum and elytra. So, the black hairless spots appear smaller.
