Tree Frogs in Iowa: Species Guide & Merchandise
Explore tree frog species in Iowa and find the perfect tree frog t-shirt or sweatshirt. Our guide covers the gray tree frog, Cope's gray tree frog, and more, plus a selection of frog-themed apparel.
The Short Answer: Iowa is home to two main tree frog species: the gray tree frog (Hyla versicolor) and Cope's gray tree frog (Hyla chrysoscelis). Both are nearly identical but can be told apart by their calls. They live in wooded areas, near ponds, and sometimes visit backyard trees. You can show your love for these amphibians with tree frog clothing and gifts.
What Tree Frog Species Live in Iowa?
Iowa hosts only two tree frog species: the gray tree frog (Hyla versicolor) and Cope's gray tree frog (Hyla chrysoscelis). They look almost the same—gray or green with dark blotches—and both can change color. The easiest way to tell them apart is by their calls: the gray tree frog has a slow, musical trill, while Cope's has a faster, harsher trill. They are found statewide in forests, parks, and near water.
Where Can You Find Tree Frogs in Iowa?
Gray tree frogs and Cope's gray tree frogs live in deciduous woodlands, often near ponds or streams. They climb trees and hide under bark or in tree holes. In summer, males call from shrubs and trees near water to attract mates. You might also spot them on windows or porch lights at night, hunting for insects.

Are Iowa's Tree Frogs Endangered?
Neither gray tree frog nor Cope's gray tree frog is endangered in Iowa. They are both listed as species of least concern. However, habitat loss and pesticide use can harm local populations. You can help by planting native trees and avoiding chemicals near ponds.
What Do Tree Frogs in Iowa Eat?
Tree frogs eat insects: moths, flies, beetles, crickets, and other small bugs. They hunt at night, using their sticky tongues to catch prey. If you have a garden tree frog visitor, they help control pests naturally.
When Do Tree Frogs Call in Iowa?
Calling season runs from April to July, peaking in May and June. Males call after rain or on warm humid nights. The gray tree frog's slow trill can last up to 30 seconds, while Cope's is faster and shorter. I can trace my interest in frog calls back to a camping trip in Ledges State Park.
How to Attract Tree Frogs to Your Yard?
To attract tree frogs, provide water (a small pond or birdbath), trees or shrubs for climbing, and avoid pesticides. Leave leaf litter for hiding spots. You might also install a frog house—a simple wooden box attached to a tree. For more tips, check out our wildlife gardening guide.
Frequently Asked Questions
Can you keep gray tree frogs as pets in Iowa?
Yes, but you need a permit from the Iowa Department of Natural Resources. Wild tree frogs may carry diseases, so it's better to observe them outside.
What is the difference between gray tree frog and Cope's gray tree frog?
They look identical, but Cope's has a faster call and 2n=24 chromosomes (gray has 4n=48). You need a genetic test or careful hearing to tell them apart.
Do tree frogs hibernate in Iowa?
Yes, they hibernate under leaf litter, logs, or in tree crevices from October to March. They produce glycerol to prevent freezing.
Are tree frogs poisonous to pets or humans?
Gray tree frogs secrete a mild toxin that can irritate eyes or mouth but is not dangerous. Still, wash hands after handling.
