Field Notes
May 10, 2013. It was a overcast day, with lots of Cumulonimbus clouds in the air. We hiked along the school's nature trail. There is a river that runs along the side of the trail. We stopped and chose a spot to sample. We scooped up a bucket full of mud. Then we searched through the mud. We went trough it with a small net and we took out all the bugs and living organisms. We found caddisfly larva, mayfly nymphs, and a alderfly.

Supporting Evidence

The alderfly that we found had a long segmented body with a hard head, just like it was supposed to be.
Photo of my evidence.
Most alderfly larva are typically between 17-20 mm long. The alderfly that we found was about 20 mm long.
Photo of my evidence.
The alderfly had seven filaments extending from the side of the body. It also had a tail-like filament on the end of the abdomen just like an alderfly.

Thank you for your information!:)

Your drawing is good and it sounds like fun

That looks like a hellgrammite to me which I guess is in the same order as alderflies...

Awesome photos and sketch, and I really like your field notes! :)

This is definitely a dobsonfly, but because both dobsonfly and alderfly are in the same order, the observation was confirmed!

thanks, we like the feed back :)

Nice username, by the way :)
