I took an old dish and filled it with very ripe or foulded and/or fermenting prunes and created my own drive-in restaurant for the Red Admiral. Sometimes a Comma Butterfly and/or Speckled Wood also visits my restaurant.
It's funny how many other insects like different kind of flies, bees and wasps come too and how quick the prunes are eaten. On sunny days I counted at least 20 Red Admirals!
Each day I had to fill the dish again with 'fresh' foulded prunes....their happy meal!
