I found two of this larvae under the bark of a rotten trunk, could they be Tephritidae larvae?

They are long 3-4 mm

Thanks for the help!

Certainly not. Lonchaeiadae, Pallopteridae, Ulidiidae, maybe, but not Tephritidae (some species have larvae living under bark in the Oriental Region and its neiborhood, but not in Europe).

---

Possibly Chloropidae (form of mouthhooks + this type of posterior spiracles)

Thank you for the answer, I hope to see the adult!

Just another thing, today I checked for to see if they was still alive, well they are fine and .. they jump! I don't know how they do but I saw they flex and jump up to 2-3 cm! Like a springtails. Really funny.

Maybe this image could help more, anterior spiracle with 6 lobes:

Larvae like these found under bark in Europe are, as Valery says, most likely Lonchaeidae or Pallopteridae - two closely related families so its not always easy to distinguish between the larvae from photographs. Lonchaeidae larvae are known to "jump" (one species is called saltans = the leaper). My advice is to keep them cool and moist in the material collected from under the bark and hopefully they should pupate and emerge as adults

Hi Iain,

thanks for the info! Yes, I think too it could be a Lonchaeidae.
I'm trying to keep them cool and with the material that I collected under the bark, I added some sawdust and I hope to see the adults!
