Tiny maggot like soil invaders

I'm 5 weeks into flower, and I've noticed some gnats flying around. Today, I was reading the damaging impact the larvae can have on the root system, affecting the plant in different areas. I used sm-90 on each plant, afterwards I noticed these tiny bastards crawling out of the soil. Are these just gnat larvae, or something different?

It's not gnat larvae.. Doesn't it look like a cutworm? How many are there?

Can you get some pics of the flyers?

I found maybe 6 in one plant, but the flying insects are definitely fungus gnats. The larvae looking creatures are about twice the size of the gnats, so I've pretty much ruled them out as being gnat larvae. I'm using rabbit manure from outside, even if that's not advisable.

Hopefully you got rid of all the cutworms. Do you think they may of came in with the rabbit manure?

You might want to post a pic of a dead gnat, just to make sure you don't have root aphids. They are similar looking with the aphids having two appendages coming out of their rear end, often referred to 'tail pipes'.
