Those larvae were on a Phillyrea latifolia bush, amongst mobile and fixed larvae of Euphyllura phillyreae. My hypothesis, after discussion on our French forum, is that it is a larva predating this psyll. There is an article by Laskal & al. (https://www.eje.c.../03/20.pdf)describing the larval stages of the genus Scaeva, with amongst other species, Scaeva mecogramma as predator of Euphyllurea psyllids.

Laskal says that the larva is green with a white medial stripe. On my pictures, it is difficult to say whether the fluffy ornamentation is natural or the result of accumulation of cottony remains of the preys.

What do you think about this?
Thanks in advance.

Hello Pierre, my comment:
Without seeing the prp (posterior respiratory process) it's very difficult or impossible to identify the larva - which resembles some sawfly larvae.

Eric,

Thanks for your comments.
I think we would see the cephalic capsule on those pictures, in the case of sawfly larvae.
