Description

Rutpela maculata – mating pair

Rutpela maculata – in-flight

The adults grow up to 13–20 millimetres (0.51–0.79 in). The head and pronotum are dark-brown, while elytra are yellowish, with black dots and stripes, rough imitations of wasps, which probably gives them some protection from birds.

Biology

Adults can be encountered from May through August, completing their life cycle in two-three years. They only live two-four weeks. They are very common flower-visitors, especially Apiaceae species, feeding on pollen and the nectar. Larvae are polyphagous in deciduous trees, mainly feeding on Picea abies, Corylus avellana, Fagus sylvatica, Castanea sativa and Ostrya carpinifolia, as well as on Quercus, Carpinus, Salix, Alnus, Populus and Betula species.
