Earthworms ... it is how?

[Did67]

These are beetle larvae. They seem a bit big to be larvae or beetle rose chafer (useful). There is just a small detail to distinguish (but I do not remember).

The Cetonids actually lay in the hot compost.

Your worms (probably Eisenia, used in vermicomposting) are, for gardeners, what I kindly call "wankers". Epigés, having a very fast multiplication. They certainly help break down organic matter, but they don't do anything useful for the soil otherwise. They should therefore especially not be assimilated to "anecics", which themselves are very useful. Their "urine" is a "natural" nitrogen fertilizer, but under the heap, what is it for?

Now, if that happens, by breaking down organic matter faster, it heats up less (because the OM that they break down is no longer food for bacteria, which "heat up, they ...), and is no longer attractive for the beetle in question to lay eggs there!

Not knowing if it is helpful or harmful, I can not tell you whether it is positive or negative! [I will not repeat my verse on the fact that the compost is not in itself a good idea, in my opinion]

I've already found in flower beds where they had put the cheap potting soil.

There, it was almost certainly larvae of cetonia, very customary "potting soil" of the trade, which is in fact waste from a composting platform. Often infested with keto larvae ...

In the ground you probably right but you saw the size of worms compared to the glove?
If it is an adult hand I lean more to worms stag beetle. In addition it has the most abdomen towards the tail

Yes Yes ! We agree. I wrote : "They seem a little big to me for being chafer or keto larvae (useful)"

According to your soil, I think it was the Cetonids ...

I find them a funny face for stag beetle larvae ... It would not rather larvae as found in the frames?

Ahmed can actually be Capricorn larvae

[Ahmed]

Yes, that's possible, but I prefer to remain vague as these wood boring insects have fairly similar larvae ...

[izentrop]

Yes, Capricorn http://www.ien-argenteuil-nord.ac-versa ... sectes.pdf

Yesterday I cleaned my deck, some waste paper / cardboard (for ignition BBQ) very wet hung out there: some beautiful earthworm staying there ... they moved Hop fissa under the hay from the garden!

The old boxes are perhaps a way to attract some beautiful specimens of worms ???

They are probably epigeas, degraders of organic matter. The ones I call "wankers" (from the gardener's point of view). Multiply quickly. Live under organic matter, like vermicomposting ...

And not anecic, real engineers who assist / deputize lazy gardener.

Now they are not "harmful". They are less useful than anecics ...
