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]

Taxonomy

Rhagium mordax was first named Leptura mordax by Charles De Geer in 1775. [9]

There are five formally described varieties: [2]

<span class="mw-page-title-main">Lepturinae</span> Subfamily of beetles

Lepturinae, the lepturine beetles, is a subfamily of the longhorn beetle family (Cerambycidae), containing about 150 genera worldwide. This lineage is most diverse in the Northern Hemisphere. Until recently the subfamily Necydalinae was included within the lepturines, but this has been recently recognized as a separate subfamily. Nine tribes are usually recognized today, with a tenth, Caraphiini, created in 2016. A few genera are of uncertain placement within the subfamily.

<i>Oemona hirta</i> Longicorn beetle native to New Zealand

Oemona hirta, the lemon tree borer, also known as the whistling beetle or the singing beetle, is a longhorn beetle endemic to New Zealand. Its larvae are generalist feeders, boring into the wood of a wide variety of trees, native and introduced. When citrus orchards were first established in New Zealand, this beetle started inflicting serious damage, and so gained the name "lemon tree borer". Four species within the genus Oemona have been identified, suggesting that more species could be found. When disturbed by predators or humans, the adult beetle stridulates creating a "rasp" or "squeak" sound by rubbing its thorax and head together against an area of thin ridges. Māori would eat a liquid called "pia manuka", which was produced by manuka trees when its wood was damaged by the larvae. When Captain Cook first arrived in NZ, his naturalists, Banks and Solander, collected a lemon tree borer in their first collection between 1769 and 1771. This oldest collected specimen can be found in the British Museum. A few years after the first collection, the species would be first described by the Danish naturalist Fabricius in 1775.
