As the season began to wind down, the focus in August turned to a few rare and localised localised species that appear late on the wing - chief amongst them Tree Grayling in Lithuania and Scotch Argus in Latvia. Also encountered a Brown Hairstreak, two Brown Argus, a few more Chalkhill Blues and, major rarities, a Clouded Yellow and a second Meleager's Blue.

Whilst searching for Chalkhill Blues in southern Lithuania on 30 July, I discovered a female Meleager's Blue (Meleageria daphnis) taking nectar from Tansy (Tanacetum vulgare) flowers. This constitutes for the first record of the species in Lithuania and the Baltic States. Remarkably, I found a second individual a week later at a distance of 550 metres from the first, this second being a male.
