This entry is Part 2 in a three-part series on organisms found in the United States in celebration of the country’s 240th birthday. Part 1, which featured some of the U.S.’s less widely-familiar vertebrate inhabitants, can be found here. This entry will go over some of the invertebrate fauna (bugs, slugs, and the like) that call the U.S. home.
There is plenty of biodiversity to celebrate in the U.S.A. that doesn’t come with an internal skeleton. Vertebrates, a single subsection of a single phylum (Chordata), represent a infinitesimal sliver of total animal diversity. How tiny? Really damn tiny. Like less than 3% of all animal species tiny. The vast majority of animal species in the U.S.A. and elsewhere are of the creepy-crawly, backbone-bereft, squiggly-wiggly variety, yet they are collectively ignored as much as anything David Faustino did after Married with Children. A bizarre and attractive example of this American mini-fauna is the eastern ox beetle (Dynastes tityus) (photo above), a type of rhinoceros beetle (Dynastinae) endemic to the eastern U.S., from Texas north to New York. Males, like the one above, have intimidating horns that they use in dominance bouts with other burly dude beetles…like tiny, six-legged bull elk…all in the aim of landing access to a mate. A close relative of this species, the Hercules beetle (Dynastes hercules), found in Central and South America, is among the largest beetles (and insects) in the world, with some males reaching the size of a Big Mac, starting off their lives as grubs that look like an albino bratwurst from Hell.
Now that we here in the good ol’ U.S. of A. have just finished the star-spangled clusterfuck that is our quadrennial duo of major political party conventions (and the 2016 Summer Olympics have started up) it seems like as good a time as any to continue to the next part of this Ameri-centric post series. I will also refrain from making any tired “spineless invertebrates” jokes in regards to politicians, tempting as it may be. Take a gander below at a selection of the underappreciated boneless beasties that make their home in the States.
