Eventually recorded new to Nottinghamshire as recently as October
2022, when leaf mines were found at Warsop Main Pit Top. This moth
should be widesread cross the county, as for some reason it had gone
unnoticed, while being recorded quite commonly in all those counties
adjacent to Nottinghamshire.
The larva initially mines the leaf petiole and the mid-rib, before
mining the leaf in its final instar. The photographs below show the
progress of one mine over the days in late October 2022, the larva
hiding in the mid-rib until the mine is large enough to be accessed. |
