Silver-washed Fritillary butterfly - an unusual species for Abington

Ross and Anne D-N saw their first Silver-washed Fritillary in their garden last week (21st July).  Whilst being a rather ragged specimen, Anne was able to identify it as a female, which visited their buddleia bushes and stayed for most of the afternoon.  
Jennifer H commented that this was likely only the second report of this species in the Abingtons over the last 10 years, the previous one being in July 2018, in Jennifer's garden on the High Street.
