11 - An annual cicada calling.

We sometimes see these annual cicadas in the summer from about 2,000 feet up to around 6,000 feet in the Olympic mountains. We hear them much more often. The source of the call is not easy to locate, and it's so loud, the cicada is often much farther away (usually in a tree) than we expect. Cicadas are the largest true bugs (Order Hemiptera). Compare the shape to the tiny Psyllid Plant Bugs (see menu). Cicada nymphs live in the ground or under objects on the ground.

Thanks to Andy Hamilton at bugguide.net for the identification. (See bugguide.net images)

Mark Leppin has some excellent photos of an Okanagana sp. nymph on bugguide.net.
