Saturday 1st August 2026.
August began very nicely, with a good variety of butterflies
and moths, along with several notable insects. After checking my Moth Box and
Andy Fisher’s Moth Box, as Geoff’s MV Moth Box is currently being repaired, we took the short drive to Old Winchester Hill
this morning and enjoyed the remarkable variety of butterflies across this
magnificent area. Quite simply, the whole place was alive with butterflies,
especially Chalkhill Blues, our first of the year, and Clouded Yellows.
The weather certainly helped, and despite much of England
being in drought, the insects here seemed unaffected today. The birdlife was
quieter than expected, though a few notable birds were seen. The plant life was
also impressive, with the slopes around the hill awash with flowers. Yet again,
the weather was same as usual. Very warm sunshine and the occasional breeze
coming in from the north-west.
My Moth Box:
Another excellent morning for Moths in my garden where there
were 95 moths of 26 species recorded this morning before I headed off to
Cowplain. I was in the garden by 5.45am and carefully checked in and around the
Box. At this time of the morning, it is relatively cool, but I knew it was
going to heat up later in the morning.
There were a respectable number of migrant moths to go
through and that included my second Portland Ribbon Wave of the year, sat on
the white board behind the Box. A Langmaid’s Yellow Underwing, 2 Golden
Twin-spots, 2 Rusty Acorn Piercers (Cydia amplana) and 3 Rusty-dot Pearls (Udea
ferrugalis) were the rest of the migrant Moths.
Other notable moths included a Poplar Hawk-moth on one of
the outside egg trays, a Plumed Fan-foot, and a frustrating Blood-vein. The
latter was upside down in one of the egg trays, so I tipped the tray over to
catch it and found it was still alive. It perched on my finger, but just as I
was about to focus my mobile phone camera on it, the blighter flew off!
Once again, there was another explosion in numbers of Apple
Leaf Miners with a massive 53+ individuals recorded. My second Common Fern Moth
of the year was also present at the bottom of the Moth Box. The Moths recorded
here this morning included the following:

While I was checking the Moth Box, a Small White butterfly landed on the white board behind it, and I heard Canada Geese honking overhead, although I did not see them. Later, while walking the dogs after breakfast, I saw at least eight Common Swifts swirling above the houses at the bottom of my road. Their numbers are now declining here in Southsea as they begin their return to warmer regions.
Andy Fishers Moth Box, Cowplain Marsh:
(I arrived at Andy’s house at approximately 7.45am and,
after making coffee, began checking the moth box. Geoff explained that his own
moth box was being repaired because the electrical fitting securing the bulb
had become loose; consequently, Andy’s moth box had been used overnight.
The trap produced up to 25 moths representing 18 species,
including several migrants. These comprised two Small Mottled Willows, a single
Turnip Moth, and the micro-moths Rush Veneer (Nomophila noctuella) and
Rusty-dot Pearl (Udea ferrugalis). A fresh Maiden’s Blush was also present on
one of the egg trays, which was pleasing to observe. The moths recorded at this
location during the morning were as follows:

While checking the Moth Box, I recorded a calling Great
Spotted Woodpecker and Nuthatch in nearby gardens. A Chiffchaff was also calling
nearby and later flew from a tree. Two Coal Tits were seen and heard in the
garden, while a flock of ten Starlings and a Linnet flew over.
Earlier this week, Geoff heard a Dunlin flying over the
garden late in the evening and Andy had a Hummingbird Hawk-moth in the garden
on Wednesday.
Old Winchester Hill, Meon Valley:
We arrived at the site at around 9am to find the car park
almost empty. Conditions were favourable, with clear blue skies and a light
breeze. Although I had hoped for migrant birds such as Wheatear or Whinchat,
neither was recorded during our five-hour visit. Instead, the abundance of
plants and insects in the sunshine was particularly striking.
Bird activity was relatively limited, with few signs of
migration. Several Blackcaps, Chiffchaffs and Willow Warblers were present,
though in lower numbers than expected. I have still not seen a Wheatear this
year. A few Common Whitethroats were also briefly observed along the hilltop.
Raptors recorded today included Common Buzzard, Red Kite and
a male Kestrel hunting over the valley. Geoff heard a Bullfinch calling from
the bushes, although it was not seen, and no flycatchers were encountered on
the route to the fort. A few Swallows passed overhead, with a brief possible
sighting of two Sand Martins heading south. Yellowhammers were present in small
numbers, including one carrying food, suggesting possible nearby nesting. While
we were seated near the fort entrance, a pair of Ravens flew over before
heading east.
The plant life was exceptional. Yellow Wild Parsnip, purple Knapweed and Wild Marjoram, and great white drifts of Wild Carrot drew in butterflies everywhere we looked. It was not long before we found our first Chalkhill Blues butterflies of the year, and the south slope below the fort was alive with them. At one point, as we paused for lunch, Geoff’s sandwiches, in fact, I watched six males chasing a female low across the slope. Having found my first Clouded Yellows earlier in the week, I was delighted to see Old Winchester Hill teeming with them; even an estimate of 30 individuals may well have been conservative.
The Chalkhill Blues were not the only firsts of the year. We
also recorded our first Silver-spotted Skippers here, with two individuals seen,
and Geoff found my first Brown Argus of the year near the fort entrance. The
butterflies recorded during the visit were as follows:
·
Chalkhill Blue
·
Common Blue
·
Brown Argus
·
Clouded Yellow
·
Small Heath
·
Meadow Brown
·
Gatekeeper
·
Red Admiral
·
Small White
·
Large White
·
Dark-green Fritillary
·
Small Tortoiseshell
·
Speckled Wood
·
Comma
Insects were everywhere. Four
grasshopper species were seen or heard, including Common Field, Common Green
and Meadow Grasshoppers, while Roesel’s and Dark Bush-crickets remained hidden
but called from the vegetation. Hummingbird Hawk-moths were especially
numerous, with at least ten seen well across the site. Up to two Silver Y moths
were also noted, but the highlight was undoubtedly a superb Hornet Robberfly resting
on the footpath near the top of the hill, close to the car park. It was my
first ever sighting of this remarkable insect, and what a striking creature it
was. Two dragonflies were seen: one was certainly an Emperor Dragonfly, while
the other proved difficult to identify, though the closest possibility appeared
to be a dark Migrant Hawker.
The mammal sightings added a
quieter charm to the day. A distant Roe Deer was seen crossing a field on the
farm west of the fort’s south slope, searching patiently for a way over the
fence before eventually succeeding. Later, Geoff and I heard rustling beneath
the vegetation and watched the stems twitch as a probable Shrew species moved unseen
below. It refused to show itself, but the mystery held our attention completely,
one of those simple wildlife moments that can be unexpectedly absorbing.
Although bird activity was rather subdued, Old Winchester Hill still delivered
a superb and memorable day.
