Psychidae, Diplodoma laichartingella a 1st record for Calderdale 17 03 2013
Finally found some Psychidae Cases after quite a few Years of searching ! Found 4 ,2 were in the same Hollow the other 2 were on seperate trees.all were in hollows facing South just above the roots on large Beech Trees,perhaps judging by the size just over 11mm, and bits of insect cases and shape of the case ie Triangular ,they look like Diplodoma laichartingella ? see what others think ? regards Bri.ps Sent some pics to Harry Beaumont he agrees they are Diplodoma laichartingella.thanks for all the comments.Checked some other places today 24 03 13,searched Bob wood Colden Clough with non found,tried Eaves Wood bottom end of Colden where i struggled to find these 2 Cases in the same Hollow at the base of a Beech as previous facing South,maybe the smaller case 2nd pic down left,is a 1st Year and will emerge in 2014 ? I also found one Case in another part of Callis Wood.Bri.29 03 13 found an Old Larval Case at another site today Heights Wood Stoodley Glen and this one was still suspended from Silk Thread,with Pupal Exuvium protruding,maybe the Moth emerged last Year 2012, top pic ! this is the 1st on Oak that ive seen so far,Difficult to find on old knobbly Oaks,maybe thats the reason most are found on Beech !! Found 5 more Cases on 02 04 13 at Middle Dean Wood and a 1st one found on Sycamore.Looks like they are Locally common ! Bri.
