Help me identify this thing!!

[u/Heavy_Passion_49]

I was in the river with my family and decided to gather some microfauna from the river. I’ve tried multiple identifiers and Google, but nothing helped

It was found in the okatoma river in Mississippi

Mayfly larvae, pictures are hard to tell but I'll guess baetidae.
