Field Notes
We had a very fun time outside. We got a good group, and we saw lots of nature. Some of that nature we saw was, poison ivy, ducks, dragonflies, and a wide diversity of trees. We heard birds chirping and smelled pine. We were surprised by the vast amount of poison ivy and we thought we would see more bugs. One question we were wondering was how we were going to find the stoneflies and caddisflies without getting wet?

Supporting Evidence
Photo of my evidence.
Our bug has very pronounced pincers, while the alderfly has much smaller pincers. This is how we know that our bug is a dobsonfly larva and not an alderfly.
Photo of my evidence.
Our bug has 2 bare tails, while the alderfly has 1 single feathery tail. This is how we know it is a dobsonfly larva, and not an alderfly.

Our bug has no pinchers on the bottom off its feet, unlike the alderfly which has many pinchers on the bottom of its feet.

Good job with the identification! Your pictures and drawing s of the habitat are good supporting evidence.

Thank you very much!

Hi gmsstarfish,

Beautiful photos and written evidence! Your coordinates appear to be a bit off, however. If you reply to this comment with the correct coordinates, we'll fix that for you right away.

Thank you for telling us, we had the coordinates of the pond but for some reason it put us in Waterville. The correct coordinates are: 43.6643, -70.4453.

Thanks for clearing that up. Looks like you're back on track. Good work, gmsstarfish!
