Macroinvertebrate Samples
We think this is a caddisfly.
We have no idea what this is. Can anyone help identify this
macroinvertebrate?
This looks like a riffle beetle.
Check out this mayfly nymph!
This crayfish was about 10 cm long!
Two tails, antenna, 3 pairs of legs – must be stonefly nymphs!
A few stonefly nymphs
looked like they were
getting wings!

Isopod & Stonefly Nymph
We always find lots of amphipods (scuds).
We aren’t sure what kind of
macroinvertebrate this is. It has lots
of legs, a segmented body,
and antenna.
Look at the colors on
this aquatic worm!
What new questions do you have about macroinvertebrates?
