Common Backswimmer (Notonecta glauca)

The kids caught this monster in the swimming pool - a Common Backswimmer (Notonecta glauca, #898). About 1.5 cm long, this is a predator of aquatic insects and even sometimes tadpoles. It can even give anyone handling it a bit of a nip too. This one must have been flying around in search of a new pond. It’s a similar-looking bug, but a lot larger and more impressive than the water boatmen who occasionally wind up in my moth trap.
