At the start of this year I found my first moth larvae living in self-constructed coverings of spores on the underside of fern leaves. At that occasion, the ferns were Hart’s-tongues (Asplenium scolopendrium) and the moth larvae were Psychoides filicivora. However, there is another moth species that lives like this on fern fronds so, when I found this larva last week on one of the Polypody fern species (Polypodium vulgare sensu lato), I was hoping I’d found the second species, Psychoides verhuella. Unfortunately, I had not but I was still pleased to have found P. filicivora on a different fern species. My search for the other moth species continues.
