Sonoran Treefrog

Hyla (Dryophytes) wrightorum
(Taylor, 1939)
Sonora, Mexico. August 20, 2011

It was a rainy night in the Sierra Madre, and the highway from Yecora east towards Chihuahua was littered with squashed toads and frogs. I managed to find a few live treefrogs, and scooted them off the road. Later, I heard males calling from a roadside ditch, and stopped for pictures. Usually I have good luck with this, but this time I only managed to get one ‘ok’ photo.

At the time, I thought these were Hyla eximia, but these Sierra Madre populations were all lumped into Hyla wrightorum, which occurs as far north as the Mogollon Rim in Arizona. Tomorrow, they may be something else. The Holarctic Hyla of North America were all dumped into Dryophytes by Duellman, Marion, and Hedges, 2016, which was (in my opinion) pointless and unnecessary.
