Gordon Hart writes from the Highlands: There was lots of activity yesterday here (Tuesday June 3). There were at least four Pale Tiger Swallowtails and one Western Tiger Swallowtail on the rhododendron flowers, plus a worn Green Comma nearby. There was also a Lorquin’s Admiral, our first this year for here. There were many bees and a few dragonflies. Here is one of them. Thanks for Dr Rob Cannings for the identification.
