I`m missing Pwll!

I`m missing my ex-Pwll garden trap site with its moth diversity and nearby varied habitats, especially in the present stay-at-home circumstances! Nowadays in the Llanelli suburbs, with all its competing street lamps etc, I could only manage 26 species last night (10/4), though numbers were good eg 4 pine beauties (sorry again, Steve!) and 6 frosted greens. As with Sam, I had my first Dyseriocrania subpurpurella (x2) last night (hardly surprising as the trap was virtually under a birch tree) and also an oak-tree pug to join the already-out brindled, double-striped and v pugs. Personal FFYs included flame shoulder, brimstone moth and pale pinion. My contribution to the migrant tally was perhaps less interesting than Sam`s dark sword-grass, but welcome nevertheless - it was a silver y.

                                                       Above: last night`s silver y.

Yesterday afternoon, I spotted a female brimstone butterfly flying around the garden (males have been regular during the sunny past week) and what was interesting is that she alighted to feed at some flowers of periwinkle. I have noticed this before - at Pwll - and, again, only with female brimstones. At Pwll, it was at flowers of greater periwinkle Vinca major, whereas yesterday the female was at flowers of Vinca minor `Dartington Star`, with its attractive stellate flowers. The Vincas are of southern European origin, though long naturalised in Britain, and I wonder if moths with long probosces are the main visitors to flowers in those part?
(P.S. I have just read online that only insects possessing a long proboscis - certain butterflies, bees and hawk-moths are typical flower visitors to Vinca).
