Gall wasp

Cynipidae fam


A pale green ball, 1 cm in diameter, hard on touch. Attached under the leaf and provokes a pale green discoloration on the other side (Photo 4). Some brown powder, probably excrements, inside the gall. Seems to cause the whole leaf to decay, while still on the stem.


Lowland deciduous (protected) forest, on the banks of river Rhone.

Gotcha - and thanks AngelSeven for pointing the direction.

I think it's a type of Gall Wasp they induce on plants for larval development...!
