Just to underscore my continuing obsession with all things cthulhic I have found a wasp called Nanocthulhu lovecrafti on WaspWeb.
I love the way the description of this tiny wasp references Lovecraft and explains the connection - the clypeal fuscina (the three-pronged plate on the front of its head) apparently resembles the "pulpy, tentacled head" of Cthulhu. Up close it does look pretty freaking nightmarish.
WaspWeb also notes, rather drily, that the pronunciation of Cthulu is controversial. Mr Buffington must be something of a Lovecraft scholar given the sources he quotes or he just has really bad dreams.
I know of some links between the Cthulhu mythos and insects and this claims that Al Azif is the derived from the sound made by nocturnal insects. All of them? Hmm.
Thanks to the wonderful Curiosities of Biological Taxonomy there is another one. A spider called Pimoa cthulhu Hormiga. I've now seen pictures of it and, yes, it is likely to induce gibbering insanity.
According to that list Lovecraft is not well represented when it comes to naming critters or their constituent parts. Tolkien, Pratchett and Nabokov have him beat.
