Whilst I was away the trap was not operated and so it was interesting to see if much had changed in the last week. The temperature dropped to 14.5°C but there were 550 moths of 90 species.
There appears to be a second emergence of hawk moths with two fresh Small Elephants and three Elephants. Langmaid’s Yellow Underwing continues to match the similar Lesser Broad-bordered Yellow Underwing with four of each. Tiger moths are also getting going with 15 Ruby and five Garden Tigers. Dark Arches continues to be the most frequent species.
A slight increase to 15.3°C brought an increase to 465 moths but only 81 species. Small Emerald only occurs once or twice a year. A single Bright Wave kept their incredible run going and a lone Small Elephant Hawk-moth was only just recognisable it was so worn. The pyrail Rhodophaea formosa only shows up very occasionally.
A bit cooler last night (down to 13.8°C) and so a drop to 344 moths of 89 species in the main trap was not unexpected. There was an Observatory first Bisigna procerella adding colour to the catch though. With the contents of the other traps there was a good variety on show at the moth night. Plumed Fan-foot, Wood Carpet, Old Lady, and Rosy Rustic were caught in the Whitehouse whilst an interesting Pug sp could be Campanula.
It got even warmer with a minimum of 17.4°C. This resulted in 920 moths of 137 species worked out so far. The highlight was a Dewick’s Plusia. There was another Small Mottled Willow, four Bright Waves, eight Langmaid’s Yellow Underwings, two Dark Sword-grasses and singles of Silky Wainscot, Dotted Fan-foot and Evergestis limbata. Dot Moth and Lunar-spotted Pinion were new for the year.
The warm nights continue (14.9°C last night) but with any breeze there is having a bit of North in it there are not big numbers of migrants. This is more than made up for by the number of local specialities.
A Small Mottled Willow probably was a migrant but another Golden Twin-spot was probably from the Thanet population. Other records of interest included Poplar Lutestring, Peach Blossom, Pine Hawkmoth, three Pigmy Footmen, three Aphomia zelleri, two Vitula biviella and a Cynaeda dentalis. A Mottled Beauty of the form conversaria drew attention.
Hopefully this good variety will continue with our next moth night coming up on Saturday.
Another warm night (16.6°C) resulted in a catch of 588 moths of 113 species. Highlights included Golden Twin-spot, Silky and Striped Wainscot, five Langmaid’s Yellow Underwings, seven Bright Waves, yet another Pine Hawk-moth and another generation of Early Thorn. Migrants included two Delicates and a Dark Sword-grass. Scorched Carpet was new for the year.
After yesterday’s technical glitch the trap was back in action last night. The night started clear but cloud did build up and kept the temperature above 15.4°C. It felt cooler and the catch was, in recent terms, ‘only’ 567 of 88 species. There was the first adult Garden Tiger and Yellow-tail of the year. Delicates continue to show up, with two last night. Otherwise the catch was mostly good numbers of common species and local specialties such as Langmaid’s Yellow Underwing and Pigmy Footman.
A change in weather was partly welcome after yesterday’s overload of moths. Marbled White-spot was caught in the Gullies and adult Coleophora limoniella were flying around Sea-lavender on 100 Acre. There are still lots of Bright Waves along the beach too.
Low cloud, humid, and 16.2°C overnight, the trifecta of great moth conditions. And so it proved to be with over 140 species in the carpark trap alone! There were lots of highlights with Scorched Wing, Double-lobed, Grey/Dark Dagger, Swallow-tailed Moth, Mouse, Leopard Moth, Maple Prominent, Lackey, and Small Dotted Buff all new for the year. The latter two are particularly scarce here with the last records in 2013. Further traps in the Elms, Whitehouse, and the Beach brought additional Dusky Sallow, Fen Wainscot, Common Lutestring, Pale Oak Beauty, and the scarce migrant Splendid Brocade new for the year. During the day Channel Island’s Pug larva were found on Tamarisk on the sea-front.
An excellent night once the cloud rolled in. Ghost Moth, Fan-foot, Rosy Footman, Scalloped Oak, Green Silver-lines, Yarrow Pug, and Least Carpet were all new for the year, as was a surprise migrant Small Mottled Willow. Five Pigmy Footmen appeared, another Festoon, the first adult Garden Tiger, and the rare micros Cynaeda dentalis, and Aphomia zelleri. The first Metalampra italica for the Observatory was found during the day by the Cellars.
Pearly Underwing and Barred Yellow were the highlights though Common Rustic Agg., Rosy Minor, and Lesser Broad-bordered Yellow Underwing were new for the year. Two Orange-tailed Clearwings were lured to pheromones.
It remains hot during the day although the night time temperature dropped to 12.5°C.
There was another good catch with 100 species. Not lots of migrants but two more Delicates and three Silver Y’s were present. There is also a plume to be checked at a later date. New for the year were Silver Barred and Buff Arches. There was another Pine Hawk and a Bordered White. Another Forester was seen in the day too.
Another busy night. The highlight was a Golden Twin-spot which was joined by another Striped wainscot. During the day the first wave of Narrow-bordered Five-spot Burnet moths were on the wing with a nice Forester too.
