The spring peepers have grown considerably over the last few days. It's like they all hit a growth spurt at once.
One thing that I found funny though... They started the toe twitching while hunting. They'll be watching the fruit flies and they be all ready to pounce, and I see their rear toes shaking. I've observed this with my toads (and found out on here that it was totally normal!) but my tree frogs have never done it, so I honestly didn't expect the peepers to start up with it!
