Dragonflies in Colorado: identification guide and best places to start

Are dragonflies common in Colorado?

Absolutely. Colorado's mosaic of rivers, reservoirs, and irrigation ditches supports dozens of dragonfly species. You'll find them from the eastern plains up to 9,000 feet in the Rockies. The highest diversity shows up along the South Platte and Arkansas river corridors.

In Colorado, dragonflies sightings usually improve when you slow down and match your first stop to where people are most likely to notice them. Use the state wildlife hub and the route guide to narrow your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to brush, wetlands, timber, shoreline, or neighborhood cover.

Where are the best places to see dragonflies in Colorado?

Start with shallow, slow-moving water. Barr Lake State Park, Chatfield State Park, and Rocky Mountain Arsenal National Wildlife Refuge are reliable spots. Mountain lakes like those in Rocky Mountain National Park also hold good populations. Backyard ponds and garden water features can attract them too.

When is the best time of year to spot dragonflies in Colorado?

June through August is prime, with July offering the most activity. Late May can be good for early species like the Common Green Darner. Warm, still afternoons between 11 AM and 3 PM give you the best odds. Cool or windy days push them into cover.

How can I identify common dragonfly species in Colorado?

Start with size and color. The Common Green Darner has a bright green thorax and blue abdomen. Eight-spotted Skimmers show four dark wing patches. Variegated Meadowhawks are small with red bodies. For beginners, a good dragonfly identification guide helps separate lookalikes. Damselflies are smaller and fold wings along the body.

What should I bring for a day of dragonfly watching?

Bring binoculars for close looks, a field guide or phone app, and a notebook. Lightweight clothing and a hat help with the sun. A camera with a telephoto lens can capture wing patterns. Late afternoon light works best for photos. If you want to mark your trip, consider a quick dragonfly sticker for your water bottle or journal.
