2023 Butterfly Special

 Silver-Washed Fritillary

Last Thursday outside events conspired to cancel the butterfly special, but I remembered George who hoped to visit for the first time, after several missed chances, so we went ahead despite a less-than-perfect forecast.  In the Butterfly Garden was a tatty Gatekeeper, but we didn’t spot any of those during our walk.

It was very sunny at first, so the butterflies were out in abundance, but as the morning continued clouds began to build and sightings of some species became more intermittent.

We saw several gliding White Admirals on our walk, which appeared to have a hint of blue as they flew, but they were more difficult to see drinking nectar from bramble flowers.  The Silver-Washed Fritillaries were even more elusive as they flew with extreme speed usually far above our heads.  We reached Fiveways and had been there for some time when Sonia spotted a tiny hairstreak land low down on a blackthorn leaf.  It took quite some time for us all to spot it, as it was the same size as the leaves, albeit a different colour.  This relatively inconspicuous insect was a “lifer” for almost 100% of attendees.

We had a long wait at Fiveways, but didn’t see anything spectacular, so I suggested a walk along a usually rewarding straight path which catches the sun in many open areas.  We had gone some way when I noticed a large thistle, which held a nectaring male Silver-Washed Fritillary.  We were able to watch him for a decent period.  We walked back to Fiveways passing an elderly gentleman on the way.  He talked to the latter part of the group, who informed him about our lack of a Purple Emperor.  A few minutes later a Purple Emperor plummeted out of the sky and spent some time on the ground.  The first he has seen like that for 20 years.  He says he tried to call out to the tardiest of the group, but his cries went unheeded.  However, some class members drooled over his photos later.

The weather was even better on Friday, and was likely to be the final day for some time - as the forecast for the next 2 weeks is highly unsettled.  On Friday at 10 am both car parks were almost overflowing.  The White Admirals were more obliging on the ground, but not on the bramble flowers.

We waited for quite a long time at Fiveways, but most of the action came from Commas and Large Skippers with the occasional Silver-Washed Fritillary zipping past.  We couldn’t find the Black Hairstreak this time, but one of its cousins was more obliging.

On the return journey we managed to spot a brief glimpse of a female Purple Emperor in a sunlight glade.

Meanwhile, the moth trap has been growing in interest…
