SULPHUR PEARL moth added to my Moth Life List.

 Monday 3^rd August 2026.

This SULPHUR PEARL moth was a 'lifer' for me, which was found on the Church window of St. Margaret's nearby.

It is a bit like Ground-hog Day here in Southsea with continuous very warm weather, though there was a bit of cloud cover. It was overcast when I put the Moth Box on overnight, though it was clear as a bell first thing this morning at 5.45am. A very light south-easterly was blowing this morning that produced a good variety of Moths again and I was going to be in for a big surprise when I took the dogs for their early morning walk. Read on.

 

My Moth Box:

A Canary-shouldered Thorn was sat on the side of the Moth Box.

Over 130 moths, representing 29 species, were recorded this morning. Apple Leaf Miners dominated the catch once again, with at least 72 counted. When I checked the moth box first thing, dozens more could be seen flying over the garden plants.

The only new species for the year in my garden was the micro moth Chevron Grass-moth (Agriphila geniculea), an annual visitor here around this time. I also managed to rescue a Golden Twin-spot from a spider’s web, carefully removing the strands before releasing it safely; it soon flew off towards the back of the garden.

Setaceous Hebrew Character's have been scarce this year and so this one was very welcome.

The migrant moths continued to provide interest, with two Small Mottled Willows and two Turnip Moths recorded.

Among the micro moths, there were three Rusty Acorn Piercers (Cydia amplana) and six Rusty-dot Pearls. An Olive-tree Pearl (Palpita vitrealis) also flew out while I was removing one of the trays for closer inspection; unfortunately, it disappeared before I could see it again.

While walking the dogs early this morning, I followed the path behind St. Margaret’s Church on Highland Terrace and spotted a Hummingbird Hawk-moth high on the church wall. I managed to take a few photos with my mobile phone, although they were unfortunately rather poor.

The morning became even more memorable when I found my first ever SULPHUR PEARL (Sitochroa palealis) resting on one of the church windows. This time, the mobile phone photos came out much better. From what I understand, SULPHUR PEARL is a moth more often associated with downland and coastal locations, so this individual may have drifted a little inland.

In Hampshire today:

Black Terns are on the way back to the south coast and early this morning at Hill Head, there were up to 7 roosting south of the Sailing Club. This evening, four were seen in the same place. At least 4 Yellow Wagtails were on Farlington Marshes plus a Wheatear was on the Deeps area.

A juvenile Yellow-legged Gull was seen on Blashford Lakes and a Great White Egret was on the reserve also. The drake Scaup was on Hayling Oysterbeds too with a selection of Warblers seen too.

 Saturday 1^st 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 Poplar Hawk-moth graced 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.

Two Golden Twin-spots were by the Moth Box again.

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.

Portland Ribbon Wave.

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:

This Southern Oak Bush-cricket was near the back door above the Moth Box.

(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:

 

MACRO MOTHS	MICRO MOTHS
Turnip Moth x1	Brown House Moth x2
Willow Beauty x2	Common Plume x1
Double-striped Pug x1	Rush Veneer x2
Small Mottled Willow x2	Common Masoner x1
Small Dusty Wave x2	Garden Grass-veneer x2
Maiden’s Blush x1	Rusty-dot Pearl x1
Brimstone Moth x1	Hampshire Dowd x1
	Ruddy Streak x1
	Grey Knot-horn x1
	Mother of Pearl x1
	Rosy Tabby x2

 

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:

One of many Clouded Yellow butterflies seen today.

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.

Above, a female Common Blue butterfly on the main footpath and a Red-tailed Bumblebee close by.

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.

One of the magnificent views from Old Winchester Hill and below, the slopes were awash with flowering plants that attracted so many butterflies.

Above, a specialist on chalk downland, the Dwarf Thistle was growing abundantly on the south slope.

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.

Above, while chilling on the South Slope, Geoff saw a Roe Deer walking over the dry, brown fields in the distance. Below, this female Yellowhammer had food in its bill to prove suspected breeding.

Above and below, my first ever Hornet Robberfly on the main footpath.

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.
