Edit 10/22/2014: Embarrassingly, we (lab members and I) were too hasty in calling these Ambystoma annulatum eggs. In the past, we've always collected A. annulatum eggs from this particular pond every fall for behavioral studies. This year, I guess we were just on "auto-pilot" collecting egg masses, assuming they were our salamanders without taking a close look. Well, when they hatched, they were frog larvae... By looking closer at the pic I submitted here, these are clearly anuran eggs, not salamander eggs.
The puzzle then came as to which anuran eggs they were. We came across a publication that mentioned Lithobates sphenocephalus breeding in the fall in some populations of northwestern Arkansas populations (just a few miles from our site), even though these are typically spring breeders. We do very commonly see these frogs at this pond, as well.
There was another photo originally included in this observation that were clearly A. annulatum eggs. That photo has been moved to it's own observation.
Heard one male chilling sporadically in the detention pond at steeplechase subdivision in Kyle Texas.
