G. clavigera clavigera is very common among the Golofa species. Its biology has not yet been studied. Identification information can be found in Cespesdes and Ratcliffe (2010), Endrödi (1985), and Hwang (2011).

Comment: E. rugiceps (LeConte) is known to occur southeastern US and keep spreading upward to midwest states. I personally collected couple of specimens in southern Nebraska, 2014. Very common in down south. They are mostly active in between May-June to August. I have experience of collecting more than a hundred specimen in a single night with a small battery-operated blacklight within an hour. This species do not show a sexual dimorphism, therefore, genitalia must be extracted to determine the sex. In my personal collections from Shreveport, LA and Alexandria, LA, there were whole lot more females than males collected.
