I noticed today that two or three leaves of the red campion (Silene dioica) had been mined by what turned out to be larvae of the agromyzid fly Amauromyza flavifrons.
The fly larvae clearly find red campion leaves more palatable than rabbits do as these mammals seem to leave them strictly alone.
This is a new record for Emthree and only the third on the Sussex Biodiversity Record Centre's database. However, I suspect the species is actually quite common in Sussex.
