Diplodoma laichartingella

Last Friday, I found this psychid case on a Holm Oak trunk in the main car park at Merthyr Mawr dunes. Dave is happy that this is Diplodoma - which appears from the description in MBGBI Vol 2 to be the only case which is made of coarse granular material (bits of insects, plant fragments etc) and triangular in cross section. If you click on the photo to enlarge the image you can see all sorts of debris is used to construct the case.

There are only two previous VC41 records, from Lavernock in 1919 and Sully in 1934 (both made by H.M. Hallett), so it is good to know we still have this species in the county.
