Tree Frogs in Missouri: identification guide and where to start looking

1. What tree frog species are found in Missouri?

Missouri hosts four main tree frog species: the gray tree frog, Cope's gray tree frog, the green tree frog, and the boreal chorus frog (though the latter is often grouped with tree frogs). The gray tree frog and Cope's gray are nearly identical visually but differ in chromosome count. The green tree frog is bright green with a white or yellow stripe. Boreal chorus frogs are smaller with three dark stripes. The most common is the gray tree frog, found statewide in wooded areas.

2. How can you identify the common tree frogs in Missouri?

Focus on size, color, and markings. Gray tree frogs are 1.25 to 2 inches long, can be gray, green, or brown, and have a dark X-shaped mark on their back. Green tree frogs are slightly larger, smooth-skinned, and solid green with a pale side stripe. Look for large toe pads with sticky disks on both species. Cope's gray tree frog looks identical to the gray but has a faster trill. Chorus frogs have three dark stripes and lack the X mark.Learn more about tree frog identification.

3. Where in Missouri are tree frogs most often seen?

Tree frogs are most frequently reported in the Ozark Plateau and the Mississippi Alluvial Plain (Bootheel). They prefer moist, wooded areas near permanent or temporary water sources like ponds, swamps, and slow streams. In the northern part of the state, they are less common but still present along river corridors. Start by listening after dusk near water in spring.

4. When is the best time to see tree frogs in Missouri?

The best window is from late March to June, especially after warm spring rains. Males call from trees or shrubs near water to attract females. Evening and night hours are most productive. In summer, activity drops but continues near rain events. Late summer and fall you might see juveniles dispersing. Winter is quiet; tree frogs hibernate under leaf litter or in tree cavities.

5. How do tree frogs differ from similar species like chorus frogs?

Chorus frogs (Pseudacris) are often mistaken for small tree frogs. Key differences: chorus frogs are smaller (under 1.25 inches), have less prominent toe pads, and typically have three dark dorsal stripes instead of an X mark. Their call is a scraping sound like a fingernail comb, while tree frogs have a musical trill or short peep. Also, tree frogs have golden eyes; chorus frogs have darker eyes. Look for the toe pads to separate them quickly.

6. What sounds do Missouri tree frogs make?

Gray tree frogs produce a musical, birdlike trill lasting about 1-2 seconds. Green tree frogs give a single short peep repeated slowly. Cope's gray tree frog has a faster, harsher trill. Boreal chorus frogs make a slow ascending trill like a finger running over a comb. Learning these calls is the easiest way to locate them at night. Recordings are available on state agency websites.
