1. What are the most common frogs in Missouri?

The American bullfrog, green frog, and leopard frog are the species you are most likely to see. Bullfrogs can reach 8 inches and have a deep call, while green frogs are smaller with a distinctive ridge along each side. Leopard frogs have irregular dark spots and are often found in grassy areas near water. For more details on frog identification, check our/animals/froghub.

2. Where in Missouri do people usually spot frogs first?

Most sightings happen in the Ozarks and along the Missouri and Mississippi river floodplains. Look in shallow, slow-moving water with plenty of vegetation. Farm ponds, drainage ditches, and marshy areas are prime spots. The/wildlife/missouripage has more on statewide wildlife locations.

3. When is the best season for frog sightings in Missouri?

Spring and early summer are peak times, especially after warm rains from April to June. Many species breed then and are more vocal and visible. Late summer evenings can also be good, but call activity drops off by August. For a quick planning tool, use the widget below to check conditions.

4. How can you tell apart a green frog and a bullfrog?

Green frogs have a ridge (dorsolateral fold) that runs from behind the eye down the back, while bullfrogs lack this ridge and have a smoother back. Bullfrogs also grow larger and have a deeper, longer call. Juveniles can be trickier. If you see a frog with no ridges and a full tympanum (ear drum) larger than the eye, it is likely a bullfrog.

5. What do Missouri's tree frogs look like?

The gray tree frog and the bird-voiced tree frog are common. Gray tree frogs can change color from gray to green and have bright yellow patches on their inner thighs. They have large toe pads for climbing. Bird-voiced tree frogs have a distinct whistle-like call. Look for them in forests near permanent water sources.

6. Are there any rare or protected frogs in Missouri?

The Illinois chorus frog is listed as state endangered, and the plains leopard frog is a species of conservation concern. Both are found only in limited areas. If you spot a frog with a dark stripe through the eye and a small size (about 1 inch), you may have found the Illinois chorus frog. Report sightings to the Missouri Department of Conservation.

7. What should you bring for frog spotting?

A flashlight with a red filter helps observe frogs at night without startling them. For keeping a record, consider these frog-themed art prints from Easy Street Markets. They make great reminders of your sightings.
