Botany bay diamond weevil

Botany bay diamond weevil

Chrysolopus spectabilis

A species of Chrysolopus, Also known as Sapphire weevil

The body of Chrysolopus spectabilis is an elongated oval 1.5 - 2.5 cm long. The elytra are black, with irregular spots of bright metallic green. The underside of the body is shaded in matt green, and a white or green line runs the length of the animal's sides. The head, thorax and legs are black with occasional metallic green markings. The colouration varies across the year, with animals emerging later in the season having a bluer colour. The snout is about as long as the bell-shaped pronotum, and strongly curved. The geniculate antennae arise from halfway along the snout, and end in a small club. The compound eyes protrude slightly. The elytra display a row of furrows with slight depressions, and the animal's ventral side is also covered with scales. The powerful legs have a thick voering of hair on the tarsi, which have no claws. The larvae are 4 - 5 cm long; they are white, round and wrinkled, with a few hairs on their sides, and a red–brown head with black mandibles.
