Chirosia betuleti

Chirosia betuleti

Observation - Chirosia betuleti - UK and Ireland. Description: The apex of fronds of Male Fern (I think!) rolled up tightly. On unrolling yellowy-white maggots sometimes seen inside. A brown beetle came out once but I don't think this was the culprit, the maggots look more like fly maggots.
