They have a black suture with sparsely distributed black spots elsewhere on the elytra. The body of males is black with the exception of the elytra, which can have shades of olive-green. ĭynastes hercules is highly sexually dimorphic, with only males exhibiting the characteristic horns (one on the head, and a much larger one on the prothorax). This variability results from developmental mechanisms that coincide with genetic predisposition in relation to nutrition, stress, exposure to parasites, and/or physiological conditions. The size of the horn is naturally variable, more so than any variation of the size of legs, wings, or overall body size in the species. Male Hercules beetles may reach up to 173 mm (7 in) in length (including the horn), making them the longest species of beetle in the world, if jaws and/or horns are included in the measurement.
