Oberea erythrocephala, a widely distributed species (Europe except North, Middle East, Caucasus and Transaucaisa, Kazakthstan, Iran), has been described from Austria as Cerambyx erythrocephalus by Franz von Paula Schrank in 1776 [❖]. O. erythrocephala (sensu lato), together with other "spurge"-species of the Oberea's subgenus Amaurostoma, belongs thanks to extreme habitual variability among the very taxonomically problematic longhorn beetles. A number of subspecies have been described whose true validity is not entirely certain and the whole complex of taxa requires a detailed revision.

O. erythrocephala erythrocephala is a xerothermic beetle of steppes, forest-steppes, pastures, natural meadows and ruderal localities with Euphorbia stands. Its larvae develop in the basal part of the stem and roots of spurges (Euphorbia spp.), in Central Europe especially in cypress spurge (Euphorbia cyparissias). Life-cycle 1 year. Adults, active from May to July, can be found or swept from the host plants [✧].
