The next moth night is this Saturday (August 4th) at 1800. We will be looking at the results of the previous nights trapping. Everyone welcome to come along and have a look.
A two degree rise brought a further increase to 469 moths of 95 species.
Dark Arches resumed their dominance with 90. There was the first Lunar Thorn of the 2nd brood and an extremely early Flounced Rustic.
Most interest was in the smaller moths with our third ever Scoparia basistrigalis plus a Cynaeda dentalis. The latter is common along the shore near Vipers Bugloss but rarely makes it to the trap.
Another 1°C rise in temperature brought a noticeable increase in moths to 349 of 87 species. This was helped by a good selection of smaller moths including a second Evergestis limbata, two Acrobasis suavellas and an Ancylosis oblitella. Lesser Broad-bordered Yellow underwings are now taking over from Langmaid’s Yellow Underwings with five of the former and one of the latter. There was an increase in ‘migrants’ to 24 Diamondbacks and 12 Silver Ys.
Slightly warmer and so moths increased to 228 of 65 species. Bordered Pug and Small Bloodvein were notable amongst the macros. The distintive tortrix Pamenne aurana has only ever been recorded less than five times.
Although the temperature dropped to 11°C and the number of moths dropped accordingly there was still an interesting variety for tonight’s moth night. The car park trap held 147 moths of 57 species including two more Langmaids YU, a Pigmy Footman and our third ever Yponomeuta plumbella. The trap by the feeders had 65 species including Broad-barred White, White Colon, Evergestis limbata and Reed Dagger.
A trap by the Whitehouse yielded a Shore Wainscot and one by the Haven had our fifth ever Suspected.
Migrants remained quiet although there were two Dark Swordgrass.
Although numbers of commoner species are slowly dwindling in the dry conditions there is still a good variety.There were 252 moths of 67 species last night. Probably new for the year were Star-wort, Rosy Footman, and Buff Arches. There was another Langmaid’s Yellow Underwing.
It was good to return to an interesting mix of moths, they have obviously been responding well to the conditions this gives added hope for Saturdays moth night. If the drought continues things might change as one or two trees are already starting to turn brown due to the stress. Last night there were 330 moths of 100 species. Dark Arches led the way with 69. There were two more Pine Hawks, this time in fresh condition. Two Langmaid’s Yellow Underwings were new for the year and usually turn up before the similar Lesser Broad Bordered yellow Underwing. Other new moths for this year included Dusky Sallow, Dot Moth, and the distinctive pyrail Platytes alpinella.
Last night was overcast with (believe it or not) some light rain around 10, though a N breeze kept the temperature down. Nevertheless, new species for the year included Dingy Footman, Least Yellow Underwing and Swallow-tailed Moth, while Dark Arches carried its bat for a patient 102.
Last night’s efforts added Dun-bar, Brown-tail, Cloaked Minor, Scalloped Oak, Least Carpet, Garden Tiger, Drinker and Wormwood Pug to the year list, though the star find was a Scarce Black Arches; only the fourth Bay record since 1970.
With the regular recorders away on their travels, trapping will be intermittent for the next couple of weeks, but the B Team recorded the snappily-titled Lesser Broad-bordered Yellow Underwing and Mouse Moth last night, along with another Delicate, though in the field most of the Silver-ys seem to have moved on.
Last night’s efforts produced a Bordered White, a smart moth that is far from regular here, plus an influx of 250 Diamond-backs, which fits with the currently large numbers of Silver-y that are dancing about in the grassy bits of the Estate (there seems to be an influx of Large White butterflies as well).
