We seem to be getting over the run of poor weather (at least plants are going back greenish!) and electrical problems. There was a slight increase to 46 species last night. This included four Dark Swordgrasses,three Turnips and a Scarce Bordered Straw.
Windy and drizzly overnight and so only 83 moths of 32 species. Common Rustic agg. was the most frequent with 11. There was a Langmaid’s Yellow Underwing and a Scarce Bordered Straw.
Last night’s trap showed a small improvement in diversity though noticeably lacking in migrants. In fact, this was the first trap in almost two weeks without a Silver-Y. A Wormwood was a decent record being previously very rare in the area, though signs are there of an increase in the last few years.
Little to say with weather conditions still not the greatest though Scarce Bordered Straw and Dot Moth were of worthy of a mention.
Despite the almost continuous rain or drizzle it was not as quiet as I expected. There were 238 moths of 59 species. Cabbage continues its impressive showing with 24. There were also eight Garden Tigers and three Sharks. There were small numbers of migrant related species but they were probably locally bred as indicated by a dark Scarce Bordered Straw.
Another Scarce Bordered Straw, a Langmaid’s Yellow Underwing, and the first Crescent of the year were the highlights in a soggy catch of c.50 species.
In a surprise twist a Toadflax Brocade was found in the afternoon resting on the outside of the tool shed! Just the seventh record for the Bay.
A small increase in numbers from yesterday but wind speeds are still keeping things relatively quiet. A Scarce Bordered Straw was a nice surprise in the main car park trap with a Bordered Beauty another new species for the year, whilst the first Mathew’s Wainscot for a month or two was notable. The actinic heath trap set near the Whitehouse would have been productive but a shrew found out first leaving nothing but carnage.
A big tumble in temperature mean not even half the moths from yesterday’s bumper haul. Regardless new moths were to be found including Copper Underwing and Dot Moth new for the year.
Perfect conditions led to a monster night at the Bay with the carpark trap containing over 1,000 moths of 130+ species. Old Lady and Clouded Magpie were new for the year, the latter only SBBOT’s 3rd record and first since 2012. Migrants were a-plenty with 41 Silver-y’s, six Dark Sword-grass, three Rush Veneer, two Rusty Dot Pearl, and four Langmaid’s Yellow Underwings. Other interesting records include the first record of an adult Phyllonorycter leucographella, all previous were larval mines.
An actinic heath set in Big Gully proved worthwhile pulling in Double-kidney, a new moth for the area, as well local specialties such as Pigmy Footman and Oblique Striped.
Last night’s catch was surprising high considering the strong wind. Migrants were up again (presumably related to the southerly wind) but most notable for us was our third ever record of Lesser-spotted Pinion. Also new for the year was a tatty Angle-barred Pug (of the Ash Pug variety).
The stiff overnight wind ensured the catch was much reduced to a third of the number of individuals and species recorded the previous night. Olive and Satin Wave were new for the year though.
Another humid night peppered with light rain ensured another good catch this time without the migrants. There were 543 moths of 124 species identified from the car park trap. Zelleria hepariella, a distinctive little micro, was new for the recording area. Brown-veined and Webb’s Wainscot were new for the year. Other moths of note included Broad-barred White, nine Aphomia zelleri and a second wave of Rest Harrow and Reed Dagger. Away from this trap Tree-lichen Beauty was new for the year.
A warm humid night encouraged a great deal more moths onto the wing than yesterday. Over 700 moths of 100+ species were taken from the carpark trap with the clear highlight being the 4th record of Lunar Thorn for SBBOT. Bulrush Wainscot was also new for the year whilst other interesting records include the irregular Tawny-barred Angle, plus a clear increase in migrants with 14 Silver-y’s, two Rush Veneer, and three Dark Swordgrass.
Avery well attended moth night had a good variety of moths to look at. Although the traps were not as busy as they can be at this time of year there was a good range to compare. Dusky Thorn was new for the year along with Saltmarsh Plume and Catropia falsella. Migrants included nine Silver Ys, two Dark Swordgrasses, eight Diamondbacks and a Rush Veneer. The next evening is on Saturday August 5th.
Moth night Saturday 15th at 1800
Get close and personal with the previous nights catch!
A much cooler night with the temperature dropping below 8°C causing the digital thermometer to pack in. There were only 71 moths of 30 species. However another trap had the second Small Mottled Willow of the year and a sign of autumn, the first Flounced Rustic.
At last! It rained most of the night but the trap still yielded 149 moths of 48 species. This included six Silver Y’s, a Langmaid’s Yellow Underwing and a Pigmy Footman.
Slightly cooler but despite Noah launching his ark on Thanet it remained dry here. There were less moths with 83 species in the main trap. Least Yellow Underwing and Twin-spotted Wainscot were new for the year. A trap by the track at the front held Small Bloodvein and Catoptria verellus, the latter is another species colonising along the south coast.
Thats more like it! A thin covering of cloud dimmed the moon and although the minimum temperature was the same there were a lot more moths. 392 moths of 106 species were identified. Highlights included the second ever record of Plumed Fanfoot, a species which has been increasingly recorded along the south coast, and three new micro species- Bucculatrix nigricomella, Eudemis porphyrana and Prays ruficeps. The latter was apparently only first confirmed by DNA examination in 2013.
Cloaked Minor, Canary-shouldered Thorn, Small Emerald, Yellowtail, Slender Pug, Platytes alpinella and Evergestis limbata were new for the year.
Hopes of a very good night due to the humid forecast were not achieved. The sky cleared leaving a bright moon and the temperature dropped to 12.4°C despite what the forecasters said. 122 moths of 46 species were identified none of which were migrants. It is interesting to look at the changes in species since late June when the trap was last run regularly. The most frequent moth was the grass moth Chrysoteucha culmella with 11 individuals ,10 Dark Arches were next. Footman are more frequent with seven Dingy Footman last night for instance. There was only one Reddish Light Arches and a couple of Uncertains.
Singles of Small Fan-footed Wave, Yarrow Pug, and Scarce Footman were all new for the year from the Whitehouse with Shaded Broad-bar also found in reasonably good numbers.
A slight lull in proceedings of late with various staff on vacation but the traps are back out and catching well. Rosy Minor and Rosy Rustic were new overnight, with assorted goodies such as Dusky Sallow and Fen Wainscot amongst a haul of about 80 species. A few Pammene aurana have been found during the day around the Whitehouse and Middle Field, a species with only two previous records here. At least three Red-tipped Clearwings were attracted to pheromones in the Haven.
