ABH 49.155 BF 1086 Hedya salicella (White-backed Marble)
ABH 69.003 BF1981 Poplar Hawk-moth Laothoe populi
Whilst conditions and close proximity led to overlap the Yard and North Loop and its MGT ( seed Mix) yielded many veneers and species specifi to the seed mix. It was nice to see unusually the Latticed Heath at the Lagoon Site which has been absent from the lower Tag Meadow for a couple of years . Although a small single specimen , the high temperature and low wind facilitated its evening flying I have only swept these before daytime so one attracted to light was a bonus. Straw Dot Rivula sericealis and Shaded Broadbar can be seen durig the day among grasses. One specimen of Blackneck was found ( see below ) which feeds on Tufted Vetch - Vetc hes being abundant from the established seed mix planted some 25 yrs ago
The Double Lobed below is indicative of the Canary Reed Grass found along the Calder Canal and in Damp Land Inhabiting fens, damp woodland and other marshy places,
