   Marie O’Shaughnessy writes:  I was in Uplands Park this morning and found four of these diminutive creatures, Woodland Skippers, along with one Cabbage White.  No other butterflies were seen during my hour of watching the birds.


   Jeremy Tatum writes:  Yes, unless we get a late invasion of sulphurs or something, the butterfly season seems to be coming to a close, and we are by now almost restricted to Woodland Skippers and Cabbage Whites.  Be sure to report any other butterflies that you might see.  (Since I wrote that this morning, August 20, this afternoon I saw a Ringlet (Large Heath) and a Lorquin’s Admiral at Rithet’s Bog.)
