Brown Hairstreaks will be around until the second week of October. They come down over the tree canopy, 'hugging' it and the Blackthorn which is their food plant (and where the females lay their little white bun-shaped eggs).
The weather has been appalling ......... by this time last year I had recorded over 30 adults - the tally so far for me this year is 7 positives and 3 probables, all female!! If the weather settles, warms up, the wind drops and there is a bit of sun to be seen, I reckon females laden with eggs will be on the wing within a few hours laying. Main places to witness this is on Blackthorn on the tree egde in top field by little carpark, in the middle field where there is plenty of Blackthorn, and along the foreshore of the reserve ......... the butterfly glade is a popular spot at the moment because is has a micro-climate and can be very warm on a very average day.
Last year and this, females were seen on leaves in the trees edging this glade. The other place that is both interesting (an important geological fault - part of the Carew Anticline) and sheltered for BH is the main estuary side of the Limestone Ridge which is off the foreshore and further along it.
