Lepidoptera interest improved markedly, with a conspicuous arrival of Painted Lady butterflies and immigrant moths that looked to have been on the move along the western flank of a line of thunderstorms that stretched across the Channel to the east of Portland. Painted Ladys were thinly spread everywhere in numbers that must have been well into three figures over the island as a whole. Diamond-back Moths, including 23 at the Obs and 10 at St Peter's Church, made up the bulk of the immigrant numbers in the various moth-traps, but quality came in the form of a Striped Hawk-moth and 2 Small Mottled Willows at the Obs and another Small Mottled Willow at St Peter's Church.
