Scarabaeidae

English

Grapevine beetle

English
Pelidnota punctata

Pages

These large, oval beetles are 1.7 to 3 cm long. Their colour varies from yellowish orange to reddish brown. Their short antennae end in clubs made of plates called lamellae, which unfurl into a fan.

Their elytra (wing covers) have three black dots on the side and a fine black line on the dorsal portion. Southern specimens have light brown legs, while northern ones have darker legs.

The fleshy grubs are whitish and C-shaped, and may be up to 5 cm long.

Rose chafer

English
Macrodactylus subspinosus

Pages

These elongated beetles are 8 to 13 mm long. They are tan or greenish, with long orange-brown legs. The wings do not completely cover the abdomen.

The whitish grubs have brown heads. In the soil they adopt a crescent-shaped position. In the final larval stage, they have three pair of long legs and are up to 13 mm long.

Japanese beetle

English
Popillia japonica

Pages

These beetles are recognizable by their bright metallic colours. The head and thorax are usually green, and the elytra (wing covers) are copper. There are five small tufts of white hair on either side of the abdomen. They reach 12 mm long.

The white grubs have brown heads and three sets of legs. They adopt a crescent-shaped position in the soil, and may be up to 32 mm long.

Scarab beetles

Pages

These typically stout, broad beetles have an elongated or oval shaped body, and come in a variety of colours. Their antennae are clubbed and tipped with leaf-like plates called lamellae, which can be drawn into a compact ball.

Dynastes hercules

English

Description

Like most scarab beetles, the two sexes are easy to tell apart (sexually dimorphic), particularly because of the males’ horns. The males may be 50 to 175 mm long, with two pincer-like horns in front. The elytra (wing covers) are pale greenish-yellow, with widely spaced, irregular black spots and a black border.

The females are 50 to 70 mm long, with a dark brown body covered in reddish-brown fuzz. They do not have horns.
