Found this sizable, deceased insect on my back porch a couple weeks ago (it measured at least an inch long). After a bit of searching I was able to identify it as a female Smooth Ox Beetle (Strategus antaeus) – the males of this species sport long horns as do other beetles in that family. It is closely related to the Rhinoceros Beetle I found last year about this time.
I wasn’t able to learn much more about the species, except that the ones found here in Florida tend to grow larger and sport darker colors compared to those living in northern climates. Presumably something to do with the 361 days of sunshine we have down here in this part of Florida?
