Can anyone ID these worms? Black soldier fly larva

Thought these worms might be pests, Coddling Moth? or Green Apple Worm? When I pinch them between my fingers (which is difficult) they "snap". When uncovered they stop moving. They are not smooth but rather segmented with small firm "hairs" in each segment.

My hot compost pile is composed of kitchen waste, coffee grounds, redwood saw dust, and yard clippings. I've used a compost pile in the past and am currently using a wire bin now and they(worms) have been in both. I turn the pile every few days. Have not found them anywhere else in the yard. I'm concerned that this is a pest. Any help would be appreciated.

those look like black soldier fly larvae. They are not worms they are fly maggots/larvae.

They look like soldier fly grubs to me too....and that means you're lucky if you can find a way to encourage and use them. They are a way of quickly converting a significant fraction of composting materials (even vile things like dead animals, pet waste and humanure) directly into a feed yield for poultry or fish. Look up biopod and blacksoldierflyblog.com for loads of information on how to put these little guys to work for you !

Thank you Alder and Liz for your attention! I have positively identified my "worm" to be the solder fly larvae. I'm so pleased that I have (accidentally) created an environment for a wonderfully beneficial insect to thrive. My subsequent search on YouTube has revealed many soldier fly larvae videos. Thanks again
