Moths: July 2018
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.
Still breezy but warm and a big catch of moths. There were at least 542 of 102 species in the car park trap. This included 126 Silver Ys, a good total for such an active moth, and 99 Common Rustic aggs.
Other highlights included four Tree-lichen Beauties (plus two in an Actinic at the gullies), a Maidens’ Blush in each, a Delicate and a Langmaid’s Yellow Underwing. New for the year were Campion and Svenssons’ Copper Underwing.
A blustery night although the drizzle lifted. The cloud kept the temperature at 17.8°C but the wind reduced the catch to 177 moths of 56 species.
Silver Y was the commonest species. Red Underwing was new for the year but as usual did not enter the trap. The highlight was the scarce pyrail Acrobasis tumidana.
Breezy but the rain held off. 268 moths of 65 species were caught. Webbs’ Wainscot was new for theyear as was the rarely caught Dark Spinach. Small Emerald is another infrequent visitor.
As feared the weather prevented any exotic moon sightings however it was a relief to find the moth trap still in one piece after some of the swirling gusts associated with the storms last night.
The trap was quieter with hardly any Diamondbacks but there was still a good variety considering the weather.
A few more have been checked from the night before including our second Borkhausenia fuscescens and two relatively recent colonists a Vitula biviella and an Ancylosis oblitella.
Two Mv traps and an actinic run on what were warm, humid, conditions last night. Three Rest Harrows, four Tree-lichen Beauties, a Bordered Pug, a Wormwood, a Large Twin-spot Carpet, and more than 100 Diamondbacks were amongst the mv highlights. The actinic chipped in with the rarely recorded Agriphila inquinatella.
It sounds as if we will not see tonights ‘blood moon’ as heavy thunder showers are forecast. The humidity might stir up more moths though.
Although the temperature stayed at 16°C overnight it was clear and a bright moon is building. This reduced the number of moths to 215 of 81 species. The Common/Lesser Common Rustic group led the way with 26. We had our first ever Scalloped Hook-tip showing it is not just rarities which can be of note. There was the first Twin-spot Wainscot and Pimpinel Pug of the year and a second Tree-lichen Beauty.
it was as busy as hoped for with over 200 species in two traps. Surprisingly the only new one for the year so far was Tree-lichen Beauty. Amongst others Small Elephant Hawks are keeping going, the second brood of Rest Harrow is emerging and Evergestis limbata seems to have settled in the area.
Numbers dropped to 265 of 79 species. The first Canary-shouldered Thorns to make it to the main trap emerged and there was an Aphomia zelleri, a very locally distributed pyrail. Tonight looks interesting as it is humid.
The drought is beginning to affect the numbers of some commoner species such as the wainscots but the warm nights are continuing to bring an impressive variety to the trap. Small Mottled Willow was new for the year. There was the second ever record of Coleophora hemerobiella. The run of Langmaid’s Yellow Underwings continued with another single and a Chocolate-tip replaced yesterday’s Scarce Chocolate-tip.
Late news from yesterday a Six-belted Clearwing was tempted to pheromone lure in the afternoon. Some more i.d’s from yesterday included a second Haworth’s Pug, several Yarrow Pugs and a Eudonia lineola.
Last night was warm at 16.8°C and overcast resulting in a big catch of 523 moths of 120 species. The most frequent was Agriphila straminella with 71 closely followed by Dark Arches with 62. There was our second Scarce Chocolate-tip. Migrant species included 41 Silver Y’s, a Dark Swordgrass and a Rush Veneer. All of these could be progeny of earlier arrivals. Five Reed Daggers, a Langmaid’s Yellow Underwing, a Broad-barred White, an Evergestis limbata and a Dioryctria abietella were also of note.
Although rain was forecast yesterday it was only light drizzle here. This was enough to give a humid if slightly cooler night. Moths like humidity and the main trap increased to 385 moths of 81 species, with several still to work out. The feeders trap did not have quite as many but did have more species. Highlights from the latter included Dewick’s Plusia, Haworths Pug, Silver-barred and the first Canary-shouldered Thorn of the year. The main trap had a Pigmy Footman of ssp pallifrons, which is normally restricted to the Dungeness area, and yet another White Colon.
Cloud kept the temperature to a balmy 17°C and so despite the drought moths increased to 372 of 98 species. Silver Ys put in a good show with 33,along with seven Dark Swordgrass and there was another Evergestis limbata. The best moth was a Scarce Chocolate-tip.
The clear sky last night allowed the temperature to drop to a ‘chilly’ 10.3°C. The number of moths dropped proportionately to 176 of 61 species. Rosy Rustic, Oak Eggar and Cloaked Minor were new for the year. Black Arches was new for the year the previous night.
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 fourth 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).
