Description

edit

Enoplocerus armillatus exhibits strong sexual dimorphism and is one of the largest Cerambycids. Females reach a length of 70–80 millimetres (2.8–3.1 in) and males 110–120 millimetres (4.3–4.7 in), but specimens up to 150 millimetres (5.9 in) have been captured. Males have impressive and large mandibles. This species is characterized by very long black antennae, pale brown elytra, quite thick forelegs, and four sharp spines on both sides of the prothorax. It has diurnal habits and it is frugivorous and attracted by tree exudates, while larvae are root borers, feeding on decaying materials.

Distribution and habitat

edit

Enoplocerus armillatus can be found from Costa Rica to Argentina and Brazil. It prefers dry or partially wet areas, at an elevation of about 0–1,200 metres (0–3,937 ft).
