Petfinder, meet bugfinder.

Specifically, a bug so big, so creepy, so like-the-alien-in-Alien-looking, that when I saw it it crawl out of a fist-sized hole in a tree near Britannia Beach, it made me skid my bike to stop to ask:"What the hell is that thing?"

The brightly coloured, wasplike insect was on a tree that had been badly damaged by a pileated woodpecker. It was at least 15 centimetres long, with most of that being an enormous spike on its back end. If that's a stinger, I worried, it could likely deliver a dose of venom straight to my heart.
