Field Notes
My class traveled to the back of the school into our little forest. There was a small stream so we investigated and found some macro invertebrates. It was slightly cloudy at 8:00 am.
Supporting Evidence
Photo of my evidence.
There are 3 long tails, a specific characteristic for mayfly nymphs.

There are feathery gills on the abdomen that rapidly flutter.

There is only one pointed toe on the end of each leg so this also points towards a mayfly. If there were two this would be a stonefly.

That mayfly looks so fluffy! I wonder if it's the mayfly itself or algae growing on it. What do you think? Pretty neat!

I believe it is just detritus stuck to the mayfly.

I agree with you, but it still makes for a neat picture! I wonder if the detritus indicates a possible decline in water quality as turbidity is increasing. Maybe our little mayfly will die soon? Hopefully not! Is there a lot of urban development in the watershed? That could explain it, or just sediment washed in from the recent rain storms.
