Great sign of microhabitat. Found on the groundlayer in ancient woodland. Thought it was woodlice, however holes only 2mm wide. No actual live specamins to see.
No interactions present.
I suspect there are a number of possible explanations for this - I'm not very familiar with the gall midge but judging by the photos here:
I wonder if these holes are too irregular to be that. Wood-boring beetles would seem to be another likely explanation.
