Flies mating

Well I got all ready to go to Whisby nature reserve today with the intension of photographing birds on the lakes . Well a lorry spillage of battery acid on the A46 put payed to that !, Got as far as town then heard about it on the local news which explained why traffic was so slow , so turned to get back home and spent some time in the garden hoping there would be some butterflies on the buddlieia which has come into flower. Well no butterflies but lots of mosquitoes and flies on the other foliage in the garden !!!
