I can't really help in identifying, but it probably would help to know why you want to identify them and for what purpose.

My really short answer to your question, if they're living in wet compost that smells like manure, they're almost certainly compost worms and will turn out great compost - if that's what you're looking for, you're set.

In terms of care and feeding, since you're in a hot environment, just keep it reasonably wet - by which I don't mean soaking, just damp - and ideally somewhat protected from the sun/heat. If it's a compost pile, should be fine as long as it's big enough and with access to ground for them to hide from the heat and kept moist. Add some cardboard or other 'bedding', likely pre-soaked, also as a buffer/safe space. Turn the pile infrequently.

At any rate, sounds like you've created a great environment for them and they're multiplying. To me the manure smell means it might be a bit too wet, but then again, never argue with results.

thank you very much for the info. i tried to do a diy stack of buckets to compost kitchen waiste with bait store worms, but i dont know anything about worms other than how to put them on a hook. needless to say as i read most people kill theyr first batch. i am realy glad to read these are most likely a compost worm. that is what i was trying to raise the bait store worms for. know i might do a how to video for youtube on how to get free compost worms. i think what i did would work most anywhere except a desert, considering i have never found any worms near my house.

again thank you very much.

My pleasure. This is how I started too - big pile of leaves, clippings and apples that accumulated by necessity, and when I dug it up, was wild with worms. Those populated my bins nicely. Now I know where to look, I find them all over the place, and in fact they usually show up in the bins without me much trying.
Some compost worms are used as bait worms, but for the most part bait worms probably are not compost worms - or at least not reliably so. Worms that just 'show up' in compost piles almost always are compost worms.
I don't worry much about what kind. I'm pretty sure mine are either red wrigglers or European nightcrawlers, or maybe a mix. Either way works for me.
Look foward to seeing your video.

Funny timing (and unrelated):

"SO, any time you find loads of one species (often fairly small - but not necessarily) throughout your compost heap (or test pile), there is a very good chance youâÂÂve found a species that can serve as a valuable âÂÂcomposting wormâÂÂ."
