Bagworms on lichen trees

Part of my job with NRW is lichen conservation, and I spent most of today looking at lichens on the parkland trees in Dinefwr Park SSSI.  This has the most diverse parkland lichen flora in Wales by a country mile, and beats all but one English parklands as well.  Anyway, whilst staring at lichen-covered Oak trunks I kept an eye open for the cases of the Psychid 'bagworm' moth Luffia ferchaultella, which I found at Dinefwr in March 2012.  This time I saw it on 3 widespread trees, with just under 20 cases in total, so it is clearly well established but not especially numerous.  I also found one case on an Oak on another farm, though I can't say where because I only had permission to record the lichens [George will sympathise!].

 

There are only 3 other Carmarthenshire records - the 2012 Dinefwr one and two made by Barry in 2005 on the Llanelli Coast, with "beating tray" in the notes.  I wonder whether the notes are wrong, because I've never seen Luffia away from a hard vertical surface (tree trunk/wall/rock).
