Field Notes
The day was sunny and clear, the temperature was about 46 degrees Celsius. Tree cover was about 70%. We spent 25 min collecting and in that time identified 6 different species of Macroinvertebrates.
Supporting Evidence
Photo of my evidence.
I think I found a Caddisfly larva because it has six legs, and we know that Caddisfly larva have six legs.

It has a hard exoskeleton on its thorax with a soft abdomen, as Caddisfly larva are known to have.
Photo of my evidence.
The specimen has two small hooks at the end of it's abdomen, and we know that Caddisfly larvae have this feature. It could be confused with similar species like the Alderfly larva. However, we know that Alderfly larva have a branched tail with no hooks, so we know we found a caddisfly larva.

Hi rhodonite! Nice job on the progression of evidence to have your strongest piece last. And I agree with the VS team on your field notes, lots of good information!


Great work, rhodonite! it is so helpful that you provide information on how long you were looking. What did you learn about the water quality of your stream?

Great evidence and reasoning in your observation!

~The Vital Signs Team

I came to the conclusion that the water quality is good based on the pollution tolerance of the species that we found. Most of the species we found were pollution sensitive while the others were only somewhat pollution tolerant.

Thanks for the feedback!
