Specific name means "of Jamaica", of course--but not clear if the species is actually found there.
Size
25-28 mm
Identification
Large reddish-brown scarab, mandibles small, sides fringed with hairs. Male has squared-off pronotum, large horn. The similar "Ox-beetle", Strategus antaeus, has a horn projecting from each side of thorax in the male, and has no striations on elytra (1).
Range
Eastern United States: Virginia and Carolinas north at least to Rhode Island, west to Nebraska, eastern Texas. Not on Beetles of Florida checklist, so perhaps does not range that far south.
Habitat
Deciduous forests.
Season
Reported in literature July-September (North Carolina and South Carolina). Guide photos here show some records for June in that area.
Larvae feed on ash (Fraxinus spp.) roots (2). Other sources say larvae feed on decaying organic matter, may be found in compost heaps and rotting logs. Adults attracted to lights.
