These two leafmines, in the leaves of Glaucous sedge (Carex flacca), may look quite boring and nondescript but scroll down to see what lies within.

This is the stunning little larva of Elachista cinereopunctella, a moth that can be found throughout Britain but only in areas where its larval plants can be found (mainly Glaucous sedge, but some other sedges are also used). And the moth’s not actually that common in Wales, with just 13 records showing in the national biodiversity database. This may be because the adult moth is also rather nondescript (see a photo on the UK Moths website here) and few people look for and record the leaf-mining larval stage. I was lucky to be directed to the presence of these mines by my friendly local moth expert, George, though it still took some poking about the sedges in a local area of woodland to find them.
