Polk County’s Most Wanted – Triceratops Beetle
Have you seen Triceratops Beetle (Phileurus truncates)?
Conserving Carolina and botanist/ecologist David Campbell need your help in locating this month’s “Polk County’s Most Wanted—Animal,” the Triceratops Beetle (Phileurus truncates). Polk County’s Most Wanted is a community science initiative with a new challenge each month, in which you can expand the scientific understanding of the flora and fauna of Polk County.
Where should I look for Triceratops Beetle?
Triceratops beetles are woodland beetles. Larvae feed on decaying wood, especially oak. Adults are predatory and feed on the larvae of other wood-inhabiting insects, especially grubs from other types of beetles.
These beetles occur from Virginia south to Florida and west to Tennessee and southeastern Arizona and into Central America. They are commonly seen from late spring to early autumn around areas of decaying wood. In our area triceratops beetles can be spotted on warm days late into the year.
How do I identify Triceratops Beetle?
Triceratops beetles belong to a large group of beetles known as scarab beetles. Their name is derived from the three projections found on their head. They have two black horns that extend from above their large eyes and the top of the jaw curls upward to a point. These three projections resemble those seen on a triceratops fossil.
The body length ranges from 1 to 1.5 inches, making triceratops beetles one of our largest beetle species. The entire body is glossy and covered with small dimples or depressions. Short orange-brown hairs can be seen along the sides of the body and the head.
