Heat Wave!

Thursday 6th August was grey and murky but warm and humid and on a walk around Plymouth Hoe there were 3 Sandwich Terns silently diving for fish off Tinside Pool (which is now open again) and a Jersey Tiger flitting about in the ivy along The Promenade  - Autumn is here.

I had the moth box out in the back yard that night and had a decent haul of moths the next morning with the highlights being Jersey Tiger, Four-spotted Footman, Mother of Pearl, Yellow-barred Brindle, Marbled Beauty and Acleris forsskaleana.

After sorting out the trap I headed off to meet 3 work colleagues (Jen, Ada and Emily) at Admirals Hard in Stonehouse to catch the ferry across to Mount Edgecumbe to start a fund raising walk in memory of our dear work colleague Katie who sadly took her own life back in April. It was hot and sunny and humid and very still and the walk of around 12 miles around Mount Edgecumbe, Cawsands, Whitsand Bay and the Rane Pennisula was hot and sticky but very enjoyable and with some stunning scenery.

Various wildlife was seen along the walk with the highlights being a Southern Hawker dragonfly, an eclipse/immature male Eider Duck off the slipway at Cremyll with an adult and juvenile Sandwich Tern noisily diving for fish nearby, a very flitty male Oak Eggar moth rescued off the road, a Magpie Moth, 2 Sparrowhawks together overhead and a small group of Fallow Deer in the woods. Butterflies were very active in the heat too with Wall, Red Admiral, Holly Blue, Gatekeeper, Meadow Brown, Common Blue and Large White all seen.

Working a long day in the heat on Saturday 8th August was not fun but with another scorching hot day on Sunday 9th August and with the day off I decided to visit Netherclay Community Woodland near Taunton to look for Brown Hairstreaks which have been reported from here. It was sunny when I left Plymouth but by the time I arrived in Taunton it was totally overcast although it did eventually clear.

Wandering around Netherclay in the increasing heat and sunshine I soon found a Brown Hairstreak by the footpath just as it flew up into a nearby tree but shortly after I found a beautiful female egg laying in a sloe bush which gave some great views before also disappearing off into the trees. At least another 2 very showy egg laying females were found as I wandered around the footpaths and were very lovely to see - I always thought Green Hairstreak was my favourite Hairstreak but I'm not so sure now!

Also seen were a Holly Blue, a Silver-washed Fritillary, Gatekeeper, Small White, Speckled Wood, Large White and Green-veined White along with a male Beautiful Demoiselle and a Golden-ringed Dragonfly. A few birds were seen too including Bullfinch, Swallow and Chiffchaff with Raven, Green Woodpecker and Great-spotted Woodpecker all heard.

It was baking hot by the time I walked over to Silk Mills Nature Reserve across the road from Nerherclay to look for Brown Argus but I was out of luck this time. I did find a Small Skipper plus Meadow Brown and Common Blue but an Emperor Dragonfly, Blue-tailed Damselfly, Common/Azure Damselfly, Red-eyed Damselfly and Small Red-eyed Damselfly were all good to see. A showy Kingfisher, bathing Lesser Black-backed Gulls, skulky Reed Warblers and a surprise flock of 14 Common Sandpipers flushed from the reeds and noisily flying around the small lake before disappearing back into the reeds were the avian highlights.

I had the moth box out in the back yard that night and the next morning had a good haul of moths, not surprising given the warm and humid overnight conditions, and the highlights were Marbled Green, Broad-bordered Yellow Underwing and a lutescens form of Jersey Tiger.

I managed to get everything packed away before a huge thunderstorm rolled in but it quickly cleared and returned to hot and sunny conditions and so I walked over to the nearby Drake Reservoir to look for a Lesser Emperor Dragonfly reported there the previous day. Viewing was difficult though as the Reservoir footpath remains closed due to the COVID lockdown although there is no reason now why it shouldn't be reopened.  There was no sign of the Lesser Emperor but I did find a male Emperor Dragonfly patrolling around which are dominant over Lessers and will chase them off. A Common Darter, 2 Blue-tailed Damselfly, Common/Azure Damselfly and a Small Red-eyed Damselfly were also seen.

A night shift that night was a hot and sticky affair endured by all and the following night shift was even hotter but with some compensation had as I waited for the bus on Royal Parade to take me to work with 2 Hobby dashed around overhead chasing Flying Ants amongst the Herring Gulls.
