I happened to drive through Dinnington this morning and remembered Bill's blog from last month. I found large numbers of feeding traces of Psychoides on the Hart's Tongue fronds- but only above the SCC flail-mowing zone. I took a random sample home to examine iunder the microscope and found 2 P. filicivora larvae and 1 P. verhuella larva.

One frond also had several intricate Dipteran mines along the edges of the midrib, and an empty puparium which appeared to have been predated rather than to have hatched.
