This is either a Cope's Treefrog or a Gray Treefrog, both are present in Michigan. Physically they are very similar in appearance and can only be told apart in the field by their calls or in the laboratory by examining the number of chromosomes. That makes it tough on we naturalists...grin (not to mention the frog!).

As he's been around for a while and if you've heard his calls, you might be able to ID the species by listening to the difference in their calls. See the links at the bottom of

Otherwise I'd label this as Gray or Cope's Treefrog with a scientific name of Hyla sp. (meaning that it is one of the Hyla treefrog species).
