Found in leaf litter on the underside of a sycamore leaf. Is this gall midge (Hartigiola annulipes)?
No interactions present.
The picture seems to show the upperside of a fallen Sycamore leaf which has a large number of galls on the surface. These are caused by a mite, Aceria cephalonea. Hartigiola annulipes galls Beech leaves.
