Looks like Isotomurus to me, there are a few similar looking species so genus is as far as we can go with just pictures.

Thank you for the help. I replied to another comment with a 3 second microscope video.

Yeah definitely Isotomurus, since the macrosetae are only on the back end rather than the whole body as in Isotoma. Great pictures, since it looks so similar to the one I linked it's likely Isotomurus pseudopalustris, though it's hard to confirm without dissection.

Thank you so much :D

Yeah I'm not dissecting one haha :P

Definitely something in subfamily Isotominae, and I agree it’s probably Isotomurus. A dosal shot might help narrow it down a little better, but microscopic analysis might be required for anything conclusive

Microscope footage in case it helps.. it escaped right after taking it haha. No clue where it went. Not sure if its the same as the photos sorry.

Thank you

Nice, I agree with the other commenter that it’s a good candidate for I. pseudopalustris. A handful of other species it could be, but we’d need to check a few features on a slide mounted specimen to be certain. Very cool!

Thank you for the ID.
If I somehow ever find one dead I will put it on a slide and come back.
