Enoplocerus armillatus, common name giant longhorn beetle or imperious sawyer, is a species of longhorn beetle in the subfamily Prioninae of the family Cerambycidae.

Description

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

This species can be found in Argentina, Colombia, French Guiana, Guyana, Venezuela, Trinidad & Tobago, Ecuador, Peru, Brazil, Bolivia, Paraguay, Panama and Suriname.

Habitat

Enoplocerus armillatus prefers dry or partially wet areas, at an elevation of about 0–1,200 metres (0–3,937 ft).

gollark: Maybe the people competent enough to do so already *did* obtain the token.

gollark: How unfathomable.

gollark: Why not?

gollark: Surely they could just `os.listdir` or whatever?
