Phidippus jumpers are some of the largest jumping spiders in the world. Here in Montana, we have several red-backed species, all of which are about the size of a nickel. They are excellent house-guests and will rid your home of flies, roaches, and other mid-sized arthropods in a matter of days.

This adorable PNW millipede is a common denizen of nearly all moist coniferous forests from Alaska to California. It is also known as the “Almond-scented Millipede” due to the odors it produces when disturbed (hydrogen cyanide smells like almonds, apparently). But don’t worry, these little guys cant hurt you (just don’t eat it!). In fact, they are an exceptional critter to handle and explore with your young naturalists-in-training.

Native mantids are exceedingly rare in Washington, but that doesn’t make the introduced and abundant European Mantis any less photogenic. If you’re interested in finding natives, try scouring sagebrush habitats in central Washington for Litaneutria, a small gray ground mantis.

These large (3 cm), circumboreal beetles get their name from the leathery odors they emit from their exoskeleton (Osmo- means smelly, derma means skin). Adults spend most of their lives feeding on the decaying centers of fallen logs.
