Dragonflies and Damselflies of the Rocky Mountains

The first comprehensive field guide to all 111 species of dragonflies and damselflies found in the six-state Rocky Mountain region (ID, MT, WY, CO, UT, NM). From the foothills to the highest mountain meadows, this guide covers every species you're likely to encounter. Included inside are detailed range maps, field mark arrows and phenograms that tell you when each species is on the wing. Icons also show if that species is found in several national parks including Yellowstone, Rocky Mountain, and Glacier.
