Spring peepers are best known from their spring chorus, which can be deafening in the vicinity of a peeper-populated water body. Overall, we hear them far more than we see them. Counter-intuitively, in the drought of 2012, we saw a number of individuals, probably ones that have been drawn to irrigation water as natural water bodies dried up. We saw several in a particularly unusual place: on okra leaves, as seen photographed here.
These small frogs are best identified by the X on their back, as seen below. More info available from MDC.
