Strategus antaeus (Drury)
Orig. Comb: Scarabaeus antaeus Drury, 1773
18-41 mm (1)
Elytra without sutural striae. Male often has long posterior horns.
The absence of a sutural stria will easily separate S. antaeus from all other species in the genus. Strategus antaeus is somewhat variable with regard to shape, size, and color. Specimens from the southern part of the range are generally darker and larger than those from the northern part of the range. (1)

Eggs laid in burrow in ground. Larvae feed on roots.
