Description

Odontotaenius floridanus adult individuals can range in size from 30 to 40 mm. These beetles have a glossy black body and present golden hair on their legs, antennae and pronotum. A series of 10 to 15 indentations can be seen on the upper abdomen (elytra), while the upper thorax is vertically divided into two equal segments by a deep groove. The antennae are composed of 10 segments, the 3 distal ones forming a structure defined as a "lamellated club". The single horn is situated between the eyes and points forward. The lifespan of adult Odontotaenius floridanus is up to a year. A distinctive feature of these type of beetles is that they produce a screeching noise when disturbed.[2]
