Kissing Bug; fully 29 mm (>1") long. Flying around in our room at night; Palo Verde, Costa Rica. And there I was, worrying about a few pesky mosquitoes while blithely photographing the pretty bug! Turns out these things not only bite sleeping humans, they can also transmit Chagas' disease (which fortunately is not prevalent in Costa Rica, though it does occur).
