small member of the Lepidoptera family feeding on Chalk Milkwort.
No interactions present.
A very long shot.
for info, family names all end in -idae, like Pyralidae. Lepidoptera is the name of an order, not a family, and is a higher rank, including lots of different families.
thanks to corylus and David Notton for the ID. - and for the info re family names. Much appreciated.
