Warmer weather this morning, and only a light breeze, but annoyingly overcast, which would yet again restrict the insects on the wing. Several first sightings of the season today, including Common Carder Bee (Bombus pascuorum) on Green Alkanet (Pentaglottis sempervirens), Curled Rose Sawfly (Allantus cinctus) on Cherry Laurel (Prunus laurocerasus) and Harlequin Ladybird (Harmonia axyridis) […]

Cooler again and a gusty wind. Largely overcast like yesterday, but what I missed in insects on the wing I made up in what I found on leaves. I began with an unidentified tiny (3.5mm) ‘looper’ or ‘inchworm’ caterpillar of the first larval stage, probably of a Geometer moth (family Geometridae), found on a newly […]

The first day for quite a while that I have not been able to find anything new to report. So, I will have to be satisfied with posting images of species already recorded on the Downs, hopefully better than the first time. I got the day off to a start with a male Tawny Mining […]
Tuesday, 7 Apr 2026
A beautiful, cloudless sunny day with only a light breeze. Heading for over 20°C and the hottest day of the year so far, and the first day that I have ventured out in short sleeves without a jacket or sweater. These conditions have brought out the butterflies again after 12 days absence, not that there […]
Wednesday, 8 Apr 2026
Another beautiful, cloudless sunny day with only a light breeze. Likely to be hotter than yesterday. Surprisingly though, fewer butterflies around. Brimstone (Gonepteryx rhamni) still the most numerous, but Speckled Wood (Pararge aegeria) has reappeared in reasonable numbers. Like yesterday a few Peacock (Aglais io) and Orange Tip (Anthocharis cardamines) about too. A Common Buzzard […]
Thursday, 9 Apr 2026
Brimstone numbers down today, almost matched by Speckled Wood, these two by far the most dominant of the butterfly species. A bit more variety today, with 5 Peacock, 2 Orange Tip, 1 Comma, and first sightings of the season of just one each of Red Admiral and Holly Blue (Celastrina argiolus). Still large numbers of […]
Friday, 10 Apr 2026
A drop in temperature of 10°C overnight, and even though it was yet another bright day with very light winds the butterflies have disappeared again. My total for this morning was just 2, a single Speckled Wood and surprisingly my first Green-veined White (Pieris napi) of the season. I have noted a few aphids starting to […]
Monday, 13 Apr 2026
Perhaps I headed to the Downs a bit too early this morning. A very cold night again and a heavy dew, so not too many insects on the wing as they need to warm up before becoming active. Not too surprising that I only saw two butterflies, both Speckled Wood. Sycamore leaves were the chosen […]
Tuesday, 14 Apr 2026
Butterfly numbers are increasing. Good variety today, too. Brimstone (Gonepteryx rhamni) is still the dominant species, but several Peacock (Aglais io), Speckled Wood (Pararge aegeria) and Holly Blue (Celastrina argiolus) were seen, as well as single Green Hairstreak (Callophrys rubi), Orange Tip (Anthocharis cardamines) and a first of the season Small White (Pieris rapae). Doing my […]
Thursday, 16 Apr 2026
A cloudy morning with intermittent showers, so I waited until after lunch to get onto the Downs. At least the sun was shining, but it was quite windy. Butterfly numbers well down on two days ago with just a few Brimstone and Speckled Wood about, and a single Peacock. Last year was a bumper year […]
Friday, 17 Apr 2026
Another heavily overcast morning, so I waited again until just after lunch to head out and managed to get in a good sunny walk before the clouds descended again. Much like yesterday there were not too many butterflies about, with the only addition to the three species of yesterday being a few Holly Blue. I […]
Saturday, 18 Apr 2026
A warm, sunny day with little wind. Yet still no great numbers of butterflies, and still the usual suspects, Brimstone (Gonepteryx rhamni), Peacock (Aglais io), Speckled Wood (Pararge aegeria) and Holly Blue (Celastrina argiolus). The Green Longhorn moth (Adela reaumurella) seemed to be out in even bigger numbers today and swarming again too. The Common Spindle (Euonymus […]
Monday, 20 Apr 2026
A lovely sunny day, but a chilly wind keeping the temperature down a few degrees on the past week. Total butterfly count was a dismal 1, a single Speckled Wood. An adult Common Buzzard (Buteo buteo) of the rufous form was circling low over the northern part of the main grassland, surprisingly unbothered by the […]
Tuesday, 21 Apr 2026
Weather was similar to yesterday but gradually clouding over while I was out. Total butterfly count was 7, yet oddly there were 6 species seen. There were 2 Green-veined White (Pieris napi) and 1 each of Brimstone, Small White, Holly Blue, Green Hairstreak (Callophrys rubi) and a first of the season Small Copper (Lycaena phlaeas). […]
Wednesday, 22 Apr 2026
Not a cloud in the sky but quite windy. Despite the wind a better day for butterflies with dozens of Brimstone on the wing. Surprisingly the next most abundant, I stopped counting at 10, was Green Hairstreak (Callophrys rubi), along with 5 or 6 Holly Blue, a pair of Speckled Wood and a solitary Painted […]
Friday, 24 Apr 2026
On another cloudless, warm day the wind continues to blow, keeping down the butterfly sightings. Brimstone is still present in good numbers, supported by a few Speckled Wood and Holly Blue, and just single Peacock, Painted Lady and Green Hairstreak. It is the third time this month that I have seen the lone Common Buzzard […]
Saturday, 25 Apr 2026
Another cloudless, very warm day, but just a light breeze, so butterfly sightings should have been better. Sadly, they were much like yesterday. Brimstone still dominates, with a few a few Speckled Wood, Holly Blue and Green Hairstreak, and just a single Orange Tip. The second moth on the wing of the season, after hundreds […]
Monday, 27 Apr 2026
The weather very much the same as my last walk on the Downs two days ago. Disappointingly still no increase in butterfly activity. Brimstone still dominate, with a supporting cast of Speckled Wood (Pararge aegeria), Holly Blue and Green Hairstreak. I did get glimpses of what might have been one of the Skippers and an […]
Wednesday, 29 Apr 2026
Warm, mostly sunny, but a very strong wind. So, I wasn’t expecting too many butterflies on the wing. Total numbers were down on two days ago, and Brimstone still dominates, with the rest almost all Holly Blue (Celastrina argiolus), but for single Green-veined White (Pieris napi), Small Heath (Coenonympha pamphilus) and Grizzled Skipper (no photo […]
Thursday, 30 Apr 2026
Weather very similar to yesterday, but the wind not quite as strong. Butterfly numbers still not responding to the warm weather. Brimstone still the most numerous, then Holly Blue, a few Green Hairstreak, a single Small Copper, and the first Dingy Skipper (Erynnis tages) of the season. Oak trees yet again provided quite a number […]
