European chafer

Rhizotrogus majalis

Description:

Imago Adult beetles are medium-sized, light reddish-brown, and approximately 13–15 millimetres (0.51–0.59 in) long. Their pronotum features a narrow band of light-yellow hairs and the underside of the thorax has similar coloured hair. The tip of the abdomen protrudes beyond the wing covers. Wing covers have longitudinal grooves. Larvae Larvae are white-coloured and C-shaped, with a yellow-brown head and six jointed legs. The raster has two distinct rows of small spines that diverge outward at the tip of the abdomen. Fully grown larvae are 20–23 millimetres (0.79–0.91 in) long. Pupae and eggs The pupae of the European chafer resemble those of the other turf-infesting scarab beetles, such as the Japanese beetle. Pupae are about 16 millimetres (0.63 in) long. Eggs are shiny and oval, milky-white when freshly laid, but later turning dull gray, approximately 2.3 by 2.7 millimetres (0.091 × 0.11 in).

Habitat:

The European chafer (Rhizotrogus majalis, classified as Amphimallon majalis until 1978) is a beetle of the Scarabaeidae family. Formerly found in continental Europe only, this invasive species is now found at temperate latitudes in North America, where they are commonly called June bugs. The large, white grubs of R. majalis feed on the roots of most cool-latitude grasses, both wild and cultivated. This has made the European chafer an enemy of North American lawns.
