Field Notes
The pond experience was quite fun, but a few things I noticed were that there was quite a lot of poison ivy and mud which made it hard to get into the pond. I also noticed that I could hear the trees, wind, and I could also here the water. And it also smelt a lot like mud and humid and sticky leaves. And lastly I saw a lot of muck and dirt in the bottom of the pond.

Supporting Evidence
Photo of my evidence.
A first piece of evidence is its many legs. Our bug has 22 legs and 6 of them are mini legs near its head. This helps support it is a dobsonfly larva because unlike other bugs it looks very different which made it easy to identify.

A second piece of evidence is its pinchers. If you look at its's head you can see small black pinchers that stick out. This is a really strong piece of evidence that it is a dobsonfly larva because when a dobsonfly grows up they have huge pinchers that really make it easy to identify. And another thing is that dobsonfly (only females) are known to bite with their pinchers.

A final piece of evidence is the tail. Dobsonfly larva tail are at the end of its body opposite of the head. It is a small V shape, but sticking out are two long strings. This tail also a key to identifying it because you can see it really adds on to the length of the bug.

One thing that we need to make a correction on is how many legs it has. You can still identify it by using this example, but it only has 6 small legs and the others are just appendages that are coming from the abdomen.

Good job! The photos made it easy to confirm the identification.

Thank you it was a very fun experience.

Good job identifying it as Megaloptera. However, it only has three pairs of legs, or "mini-legs" as you call them. The other "leg-like" appendages are filaments that extend from the abdomen.

Thank you for the help! We will make sure that we fix our data and make the correction.
