Elater ferrugineus, the rusty click beetle, is a species of click beetle belonging to the family Elateridae.

Varietas

Varietas include:[1]

Elater ferrugineus var. morio Schilsky, 1888
Elater ferrugineus var. occitanicus de Villers, 1789

Distribution

This species is widespread in the Western Palearctic ecozone.[2][3]

Description

Elater ferrugineus can reach a length of 17–24 millimetres (0.67–0.94 in).[2][4] This species is rather variable. Head is dark brown. Pronotum and elytra of males are usually bright orange or reddish, while females show a uniform dark brown color and are smaller than males. The legs are black. The antennae are mid-brown to black. In males they extend up to the posterior edge of the pronotum, while in females they are shorter.[4]

Biology

Larvae develop in hole of ancient trees of various species, mainly oak (Quercus robur)[5], ash (Fraxinus excelsior), beech (Fagus sylvatica) and elm (Ulmus spp.). The life cycle lasts 4–6 years.[6] Pupation occurs in spring.[4] These larvae are predatory. They especially prey on hermit beetle (Osmoderma eremita) and rose chafer (Cetonia aurata).[1]

When male E. ferrugineus are attracted to a female, they release compounds that attract other males to the site. These compounds include geranyl, nerylacetone and 6-methyl-5-heptene-2-one. Attraction of males only occurs in the presence of females, ensuring increased mating opportunities.[7]
