Late September and early October have seen the arrival of a high-pressure system that has 'stuck' in place over the UK and Ireland, bringing dry days and colder nights. The circulating wind has brought warm southerly air to Ireland, leading to an influx of European species to supplement the meagre numbers of locals. At one point last week I had 7 specimens of Silver Y moth in my greenhouse.
By a strange coincidence, this is the time of year for the second generation some of our native butterflies to emerge and prepare for hibernation. A large Sunflower which I grew this year has been very attractive to Small Tortoiseshell and Peacock butterflies:
This is the first year for my new greenhouse and I tried different plants to see how they got on. I noticed after a while that pollination was largely being performed by a single male Episyrphus balteatus hoverfly:
