Craggs Friday 22nd May 2016

Counts and Comments

A very interesting night at the crags , first of all the predominant species was Brown Silver lines and the cold light N/W wind kept it pretty quiet for the time of year. The highlight was a  Devon Carpet and  a handful of Pugs which were all very worn and mainly end of season Brindled Pugs . 2 or 3 interesting ones were taken home for a closer look. One turned out to be  an Ochreous Pug which has not been recorded locally before and the other a Larch Pug which is only known from 1 other site in Calderdale. Its a great place ......looking forward to the next session.... Species recorded , Brown Silver lines 16 .Common Swift 1, Brindled Pug 6 , Devon Carpet 1 , Small Phoenix , Flame Carpet 3 ,Scalloped Hazel 4 , Rivulet 1 , Ochreous Pug 1 , Larch Pug 1 ,
