Common Blue Butterfly, male, showing his wonderful underwing patterns and colours, and just a glimpse of the blue of the leading edge on the topside of his far wing. But that's not all, there are 4 other insects in this photo. To the upper right of the butterfly is a fly (unidentified) and further right a Green Shield Bug, and to the lower left, a Red Tailed Bumblebee and his immediate (and hard to see and unidentified) another Shield Bug in brown/black colours. Such diversity. Photo taken on August 8, 2023 in Tymon Park, South Dublin.
