Explanation of Names

Life Cycle
Under most circumstances larvae probably feed exclusively on decayed wood although they will apparently feed on root material when necessary. Pupation occurs in the food substrate where an oval pupal chamber is formed. (1)
The males of S. aloeus can be separated from all other species by the characteristic shape of the genitalia; they may be easily confused with other species if external features only are used in identification. The key characters will serve adequately to separate the females from all other species.
Strategus aloeus is the most widespread, abundant, and morphologically variable species in the genus. (1)
