Honestly, Cricket Frogs are not supposed to be confusing. In Arkansas, we are at the boundary between the Northern and the Blanchard's Cricket. Frankly, I don't think these two know about a boundary. So it is best to just call them Cricket Frogs and be done with it here. All the Crickets are supposed to have a dark triangle between the eyes but I have seen many like this that have no trace. It sort of resembles a Chorus Frog but then it is not. The Chorus is always less likely to hang out in fairly dry woodlands and it does not have the stripes on its legs. This Cricket posed magnificently near the green moss and atop this fine fall oak leaf. They were popping about all over the leaf litter on this warm October day.

Cricket male in singing form. Leg striping visible here.  From south Arkansas and Keith's camera.

Cricket of several along my creek in March 2012. Good golden brown colors with difficult eye triangle. The usual rough or warty body.

Cricket that just looks like a hybrid Blanchard's and Northern. You can still see the triangle between the eyes and the leg striping.

One of the earliest frogs calling in Arkansas (except perhaps the Wood Frog) are the Chorus Frogs (see species discussion below). This one often rings out even on warm serial days in January. Fires up in earnest in February and is surely one of our commonest frogs. Call is like someone running their finger over a comb. Huge choruses of choruses can be found. Often with Spring Peepers and Leopard Frogs in March. Note the white lip. And rarely has any green tones as in the Crickets above. Peeper has the X on the back.

Previously two subspecies in Arkansas and now split into several new species (see A New North American Chorus Frog Species from the South Central United States, Lemmon et. al. 2008). They vary by the markings down the back and leg length and vocalizations. Most of the state used to have Pseudacris triseriata feriarum, which was known as the Upland Chorus Frog, and the extreme north central portion of the state is supposed to be the only incursion area of Pseudacris triseriata triseriata, the Western Chorus Frog. This frog pictured is from Faulkner county and that is the line pattern of the new Cajun Chorus Frog, P. fouquetti. Maps for the true Upland now incur into extreme NE AR.

The roadway pools on my property were tadpole happy in 2010 and many Cricket frogs were leaping about. This tadpole however is almost certainly the Chorus frogs from my local singing groups. Many smaller tads associated but I saw no black-tipped tails as seen in the Cricket group.

In Arkansas, in Spring, this is the vocalist to dominate woodland ponds. Usually in mixed song masses in March and April with Chorus and Leopard frogs. This is the Spring Peeper, now in Pseudacris, previously in Hyla, they confuse the scientists with their mixed characteristics. Song is a piercing, whistled piping note. In large groups they sound like a sustained bell. Most of the range is the P. crucifer crucifer and in FL and GA we have P. crucifer bartramiana. The Florida version has black spots on the belly. Our version has the pristine creamy belly. Both have that filigreed tattoo of an X across the back. They come in yellow, brown, gray, olive and this nice copper.

Oh, and this one wandered up onto my garage in March 07. We have literally thousands of peepers in our nearby swamp but they are rarely seen outside of breeding season. They are calling so loud I can hear them through the window as I type this.

The X in better light. 

And a hunter in my Ficus in the night bug-attracting lights. In July I never see Spring Peepers as they are quiet, but obviously they are still close and active. I was looking for Cicadas and found this stalker. 

And working by the creek on my property in March, when it was still chilly outside, I brought up this Peeper, likely a female and certainly one of the most beautiful I had ever seen. Excellent camouflage. And extraordinary markings even for this species. 
The face of the same animal. With those amazing frog eye colors.
