19/5/2013: Lady orchids & about 30% of the hybrid (Lady x Monkey) orchids are beginning to flower. Monkey orchids still in tight bud and will probably start next weekend. Green Hairstreak, Dingy Skipper, Grizzled Skipper & Small Heath flying. Hobby & Buzzard seen flying over the reserve. Bombylius discolor, a very rare bee-fly also seen on cowslips - one of the first modern records for this species in Oxfordshire!
