Pogonocherus

Pogonocherus

*Pogonocherus* Dejean, 1821 — the "Twig Longhorns" — are small, stout beetles whose cryptic, fasciculate pubescence renders them nearly invisible against bark and lichen. With 25 species across the Palearctic and 6 in Europe, they inhabit dead and dying thin branches of both deciduous and coniferous trees, where larvae develop subcortically before entering the sapwood. Adults are found on slender twigs of a remarkably wide range of host plants, from *Betula* and *Quercus* to *Abies* and *Picea*. Their camouflage is so effective that *Pogonocherus* species are easily overlooked despite being locally common across woodland habitats from sea level to 2000 m.
