College Lake didn't produce all that much although Phalonidia manniana, Calamotropha paludella, Chilo phragmitella, Southern Wainscot, Bulrush Wainscot, Twin-spotted Wainscot and Webb's Wainscot did put in appearances, mostly as singletons. The great thing here, though, is that even lights in the reeds bring in chalk grassland species and it was good to record things like Oncocera semirubella, Annulet & Tree-lichen Beauty in the same traps.
Despite having far more extensive reed-beds, Walton Lake last night was also fairly slow going but in the end produced the goods with Orthotelia sparganella (1), Chilo phragmitella (10+), Calamotropha paludella (3), Southern Wainscot (3), Bulrush Wainscot (2), Twin-spotted Wainscot (3), Brown-veined Wainscot (3), Webb's Wainscot (1) and a single rather worn Crescent. It was nice to find Orthotelia sparganella, a wetland micro I haven't seen anywhere for three or four years and for which there are only 16 previous records for VC24. All of the wainscots mentioned here are able to colonise reed-beds quite quickly and easily but Crescent seems to be a bit more fussy about the sites it occupies. It hadn't been recorded at Walton Lake since a singleton trapped by Martin Townsend during site surveys around MK at the end of the 1990s and the moth seems to be absent from some of the decent wetland sites which there are in Bucks.
