Tree Frogs in Wyoming: Identification Guide and Best Places to Start

1. Where are tree frogs most likely to be seen in Wyoming?

Look for tree frogs in Wyoming along streams, ponds, marshes, and irrigation ditches, particularly in the eastern and central parts of the state. They also turn up in backyards with water features or tall grass. For more on their habitat, check out our tree frog species hub.

In Wyoming, tree frogs 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.

2. What time of year and weather conditions are best for spotting tree frogs?

The best time is late spring through early summer (May to July), especially after warm rain showers. They are most active at dusk and during the night. Evening temperatures above 50°F trigger their calls. Learn more about Wyoming's wildlife seasons on our Wyoming wildlife page.

3. How can you tell a tree frog from other small frogs?

Tree frogs have enlarged toe pads for climbing, smooth moist skin, and a small body (usually under 2 inches). The boreal chorus frog has three dark stripes down its back and a dark stripe through the eye. Other lookalikes like the plains leopard frog lack toe pads. For more identification tips, see the tree frog identification guide.

4. What tree frog species live in Wyoming?

The only widespread true tree frog in Wyoming is the boreal chorus frog (Pseudacris maculata). The spring peeper (Pseudacris crucifer) is reported in the southeastern corner but is rare. Both are small, with the chorus frog being more common in prairie ponds.

5. Tips for finding tree frogs in backyards and wetlands

Set up a small pond or keep a rain barrel to attract them. Check under logs and leaf litter during the day. At night, use a flashlight to spot their eye shine in vegetation. Listen for the chorus frog's rising trill, which sounds like running your finger over a comb. For more tips, see our tree frog habitat page.
