Redhouse Barns, 23rd August
I ran the MV over-night and in the morning recorded 38 species. High-lights were: 2 peach blossom, 1 feathered gothic, 1 poplar hawkmoth, 2 blood-vein, 1 rush veneer, 1 Calamatropha paludella and 1 horse chestnut (1st VC record for Monmouthshire).
Horse chestnut caterpillars feed on heather. Its likely this one came in on the southerly winds from south west England.
