Whats these worms in compost ? Are they good?

Hi people. I'm in The Amazon jungle , and when i make compost here in The jungle ( climate is superhot and very wet) always appear these worms here in The compost . Before i was making compost in a valley with warm climate and i never saw these worms.



Whats these worms in compost ? Are they good?

Thanks i'm advance

I have seen very similar creatures in my garden, especially around pine leaves, in very large quantity, and I am in a cold temperate climate. I believe they are some kind of larva but am not sure of the species, genus or family.

Looks like black soldier fly larvae. They are good reducers of the material. They don't produce castings like worms but I like having them in our compost piles.

I think there are some mixed opinions on them. I put a shovel full in with the chickens for them to eat, every now and again when they are thick in the compost.

"native to the neotropical realm"--definitely a possibility!

I think those are insect/arthropod larvae rather than “worms”, which could be from a couple of different phyla separate from arthropods. However, to my non-entemologist and only been to the Amazon once eye, they could be any of thousands of different invertebrates that are native or immigrated to the Amazon jungle. The closer to the zygote an animal gets, the harder they are to distinguish without genetic testing. I would bet 10+:1 odds though that they are either beneficial or innocuous, as most species are.=

I think they are definitely insect larvae, probably of the Brachycera suborder of flies (which I believe are the headless larvae). I looked up pictures of black soldier flies and they do not look quite like Ronaldo's larvae, which are darker and hairier. My larvae looked rather closer to Ronaldo's, also, than to pictures of black soldier fly larvae, which also would probably be uncommon in this climate. It would seem odd if our larvae were actually the same species, but perhaps the same family would make sense. I wouldn't be surprised if this were the wider family of soldier flies, Stratiomyidae. I do recall seeing last year a number of flies that looked like soldier flies in that area, but I wasn't entirely sure, because I don't know much about fly taxonomy.

Edit: oh! Black soldier flies do occur in my climate! So maybe they are. I am guessing a different breed, perhaps, or maybe they're darker because they're eating better than the domestic ones.

Looks good to me:

They are black soldier fly larvae. Typically the younger instars are light in color but if the food source has tannin or other pigments the skin can be stained and the grubs appear darker. They are voracious eaters and recycle food scraps quickly. When they are present, fly larvae are out competed. Since adult black soldier flies don't eat and thus won't get into the house and contaminate fresh food like pesty flies do.

these guys found my bokashi barrel and turned it into a BSL barrel. They are voracious (here in my corner of neotropical south america) and break down my kitchen waste very quickly, adding their own contributions.
