Lithobates sphenocephalus, the Southern leopard frog; Volusia county, Florida; 16 May 2015. http://phostracks.com.
Found on Wallace road in west edinburg, Texas. Not sure if it's a rio Grande leopard frog or a southern leopard frog.
In bat-filled underpass under a 304S junction with some unknown road. Couldn't find the underpass on a map or GoogleEarth. It's near Middle Yegua Creek. There were small ditches filled with water on either side of the road. Plenty of rain from the previous few days. High humidity, around 10% cloud cover.
