Rhagium mordax, the black-spotted longhorn beetle,[1] is a species of long-horned beetle.[2] This beetle is found throughout Europe and to Kazakhstan and Russia.[2] Larvae develop in silver fir, hazel, European weeping birch, European beech, and the European chestnut.[2] Ischnoceros rusticus is an ichneumonid parasitoid wasp that feds on Rhagium mordax larvae.[2]
Description
Rhagium mordax grows from 13 to 26 millimetres (0.51 to 1.02 in) long.[3][4]: 97 In colour, they are mixed ochre and black, with one black splotch on each elytron accompanied by two pale lines on either side.[5] The beetles' bodies are covered with small yellow hairs,[6] although one distinguishing feature of the species is two bald spots on its elytra.[7]
Rhagium mordax has a long, narrow head with a distinct neck. The insect's face bears a suture and the temples are elongate with some stiff hairs. The antennae are relatively short and the first segment is wider at its tip and longer.[8]
