157 of 47 in Cambs, 15C min temp #teamMoth Still 30+ Common Wainscot, ~14 Nutmeg and Turnip, 10 White-point and all the other usual suspects. Just 3x Jersey Tigers, less than half the number of most previous sessions since they emerged. And, a Copper Underwing agg, more info in the ALT text

These two species are superficially identical as adults and can only be identified loosely by looking at several features together, especially the underside of the hindwing. The colour of the mouthparts can also help, but it is not always reliable. Some individuals cannot be separated without microscopic examination of the male genitalia (gen det).

88 of 31 moth species last night in 11C Cambs #teamMoth Common Wainscot still common, SSD and SMW not quite double figures. Straw Underwing has started to appear, their usual arrival date for me, early August

Suddenly realised our garden was like a tinderbox, all the dead wildflowers and the mounds of leaves and sticks left for the wildlife...would just takes a tiny spark from a neighbour's bbq or smouldering tab butt and we're done for. So, I've raked, compacted, and green-binned much of it

This one, Tawny-barred Angle, Macaria liturata, new for the year here, but have had it a couple of times in the past. Its scientific name could be translated as the "Blessed Smudgy One" or "Fortunate Blotched One" #teamMoth

Oak Processionary was new for the garden last night. This species is nominally Continental, but established in West London about 20y ago. It may well be spreading. Its larvae can defoliate oaks. Contact with their hairs can sometimes cause skin, eye, and lung irritation/damage

150 of 45 species, 22C, Cambs #teamMoth Another migrant among them, The Vestal (Rhodometra sacraria) named my Linnaeus for its pale yellow with a red-ish stripe purportedly resembling the robes of the Vestal Virgins, but Marren reckons he was thinking of the purple-striped toga of the Roman senate

The Vestal moth. This specimen from 2025, a pale, creamy yellow with the familiar diagonal marking on each forewing coming to a central point to form a V. Almost looks like a line of smeary pink lipstick on this one

Meanwhile, spam: Dear, I hope this email finds you well. My name is Windy, our company is a leading manufacturer of high-quality rubber magnets. I am reaching out to introduce our exceptional range of rubber magnets that are known for their superior magnetic strength and outstanding...

Seismologists replaced the Richter scale decades ago with the Moment Magnitude scale (Mw), which measures an earthquake's seismic moment rather than just the amplitude of seismic waves. This is a more accurate measure of the size of large earthquakes.

Numbers back up again last night, don't think it got below 19C in our Cambs garden 135 of 43 #teamMoth Still single figures of Jersey Tiger, but give it a couple of weeks and may well pass last year's record of 45 on one August night!

One of 8 Red Underwing I counted on the Rothschild Bungalow at Woodwalton Fen NNR yesterday. Their camouflage works best against crusty bark rather than slats. And, there's no camo at all when they're in flight, bright flash of red, black, and white, no photo tho' #teamMoth

Hornet Mimic Hoverfly, Volucella zonaria. A species considered rare in the UK until the start of WWII, but still only really present in the South and South East. It's an insect of woodland-adjacent meadows, but quite happy to live in parks and gardens with flowers. This one on our buddleia

A juvenile Swallow (Hirundo rustica) You can almost sense the trepidation in its eye almost as if it knows it's got a huge flight to make in the coming weeks #BirdOfTheDay #EyeOfTheWild (More likely it was just worried about the big eye of my zoom lens staring at it from 20 metres away)
