Field Notes
In the morning our class hiked the nature trail until we came to the stream. Our teacher had set two crayfish traps the night before and we were hoping to find some crayfish in our traps. There were no crayfish in our traps but we did catch a few minnows, hopefully next time our traps will catch crayfish. After we checked the crayfish traps we used nets to try and catch other species in the stream. We found three crayfish, caddisflies mayfly nymphs and lots mud and leaves. Our class spent some time collecting data and taking pictures before it was time to head back.
Supporting Evidence
Photo of my evidence.
Caddisfly larva are a soft segmented worm with 6 legs near the head. The organism we found had its body encased in bark so we were not able to see if was soft and segmented but we were able to clearly see the six legs when it came out to move around.
Photo of my evidence.
Caddisfly larva make a protective case from silk and other materials. These materials could be sand, sticks, leaves, or pebbles. Caddisfly larva carry their protective cases with them or attach themselves to rocks in their case. Our organism has a protective case made from bark, leaves and small sticks. Our organism carried this casing around with it while we were observing. This leads us to believe that this is indeed a caddisfly larva we are observing.
Photo of my evidence.
Caddisfly larva and their cases are often .3 to 4cm long. Our organism in its case measured about 4cm. This measurement falls within the range for a caddisfly larva.

Such a cool caddisfly picture--and, like sniffly salamander, I really love the case! In my opinion, that's the best part of the caddisfly: the case.

Cool photos!!! Caddisflies are really neat, and I think that it's cool how you captured the larva partially out of it's case.

Are you going to share photos of the crayfish and other things you found? Looks like a fun field site to explore!!

Thanks for sharing,

There are more coming, we just worked on this one as an entire class together to be sure that we all knew what a good observation looked like and how to use the flow chart and quality control check list. We go out again to collect information as small groups and post plenty of observations about our little stream!
