Field Notes
I am happy because its a beautiful day and water is nice. I smell soiled water. The mosquitos are all over the place. I was surprised that I found no pollution intolerant animals and that the pH level was so high considering the water is coming from an acidic heath.
Supporting Evidence

It has the same striped pattern on the back legs that a damselfly has on our species card.

Thanks for going out and looking for benthic macro-invertebrates (BMIs)! They are an integral part in our understanding of water quality.

I see that you think that this species is a damselfly nymph. I think it is a mayfly nymph. Normally, the tails on the damselfly are more fan-like. And, compared to a mayfly, the body on the damselfly is noticeably skinnier. The abdomen on the damselfly is more twig-like. Whenever I see a BMI with three tails, my first guess is always mayfly. Most mayflies have three tails (unless one has broken off). Though damselflies also have three tails, they are more like fans and the body of the damselfly nymph resembles the body of the damselfly adult (somewhat).

Thanks so much for getting out and identifying some BMIs for us! Keep it up!
