John Latimer's audit of August's outdoor ambiance

 The spreading dogbane plant turns yellow in anticipation of fall. Spreading dogbane is one of the first plants to turn color. Pictured is a forb with opposite-branched oval-shaped leaves. The leaves are bright yellow. The background shows many green plants, which emphasize the yellowness of the dogbane leaves.

A spreading dogbane turns yellow on August 11, 2016 near the North Shore of Lake Superior.

During the Phenology Report for the week of August 5, 2025, Staff Phenologist John Latimer covers what to expect in the long golden days of August.

Each August, Staff Phenologist John Latimer celebrates the end of deer fly season, the emergence of “Labor Day ants,” and the beginning of fall migration. It’s a busy month, full of changing colors and cavorting young animals.

One particularly enjoyable sight for John this week was a bunch of tiny tree froglets, freshly emerged from the pond where they had been growing as tadpoles (also known as polywogs) all summer. John describes initially spotting them as tiny green dots on the cattails. On further inspection, these little dots turned out to be young frogs, some still with remnants of their tails!

This week’s report also details Ruffed Grouses’ love of dust baths, how to use galls to identify goldenrods, and when to look for hazelnuts. Enjoy!

Charlie creates the Season Watch Newsletter, produces the Phenology Talkbacks show, coordinates the Phenology in the Classroom program, and writes nature-related stories for KAXE's website. Essentailly, Charlie is John Latimer's faithful sidekick and makes sure all of KAXE's nature/phenology programs find a second life online and in podcast form.


With a background in ecology and evolutionary biology, Charlie enjoys learning a little bit about everything, whether it's plants, mushrooms, or the star-nosed mole. (Fun fact: Moles store fat in their tails, so they don't outgrow their tunnels every time conditions are good.)
