The nights have been cooling way down here in Wisconsin. After a summer of record highs, we're actually unseasonably cool at the moment.

The night temperatures started dropping 2 weeks ago. I didn't put any heat on the frogs because I figured, they're native to Wisconsin, they can handle it. 2 nights ago I started putting heat on the spring peeper froglets because we dont have our heat running in the house and the outside temps are dropping to the upper 30's low 40's Fahrenheit (inside is low 60's)

The spring peepers hit an incredible growth spurt now that the temps have dropped. I wondered if the drop in temps triggered it the growth spurts because they feel the urgency of winter coming. They are all only about 1 cm shy of adult size now, where the first 6 weeks I had them, they barely seemed to grow at all.
