Overview

Pachytodes

*Pachytodes* Pic, 1891 comprises small, vividly patterned longhorns, 7–12 mm long, whose tapered bodies and bright yellow-and-black markings make them among the more recognisable flower visitors in European woodland margins. Adults are strongly diurnal and frequent flowers of Apiaceae and Rosaceae in particular, feeding on pollen and nectar throughout May to July. Larvae develop in decaying wood of a variety of deciduous trees — including stumps and exposed roots of recently dead or windthrown trees, often in moister, sheltered situations. The genus ranges across Europe, Turkey and the Caucasus, with five species in the western Palaearctic and three in Europe.
