Above photo: Micro Baetis hatch on the Mad River, June 16, 2026. Feel free to click any image to enlarge. All images shot with a Sigma 70mm macro lens . Living on the Mad River, just down the road, allows me to constantly collect insects, bring them home, and photograph them within 5 minutes. This is a luxury for a fly fisher. I h ave, for the last 25 years, kept a pretty comprehensive journal of aquatic insects that have come and gone due to farm runoff and other environmental changes. Our water-borne insects, such as the Baetis, still seem to come off in sections of the Mad River in healthy numbers. June 2026 has been somewhat prolific for Baetis hatches, which makes me very happy. Most of the Baetis hatches I have experienced in the last few weeks start and end between 10am and 12pm. These micro Baetis are approximately 7mm, which is roughly the size of a #22 hook. These tiny Dun morsels are what I have been waiting for all winter, and I am glad to see them hatching in numbers...
