Some sort of testosterone enhanced jurassic looking hornet that the cats knocked down over the weekend. About 2" long. Yeesh. Any budding entymologists know what thisun is? I will do some research.
I speculate that it is some sort of plutonium mutated hornet that was entombed in an ancient mudhole deep in a canyon here in NM, released by recent thunderstorms and in search of the dinosaurs that it snacked on millenia ago.
