From nearly invisible no-see-ums to the orb weaver spider, this place does indeed have bugs. The no-see-ums are just plain annoying. They can get through nearly any mesh screen and the way you know that they are there is the bite. It’s much more painful than a mosquito bite. Unbelievable for such a little guy. There are lots of spiders in the mangrove swamps. The Orb weaver spider is big (easily over 2” in diameter). The crab spider is only the size of a dime and looks very much like its name sake. Between the two of them, they create a bit of a gauntlet for hikers in the mangroves.
