Elater ferrugineus, the rusty click beetle, is a species of click beetle belonging to the family Elateridae.
Varietas include: [1]
This species is widespread in the Western Palearctic realm. [2] [3]
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]
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]
