Our first Moth Night of the year was a great success. Thank you all for coming. For all of this year’s dates click HERE for details.
The temperature did not drop below a muggy 18.3°C, conditions which we always hope for. There were 951 moths of 144 species and that does not include escapees and sparrow victims!
The highlight was our first record of Eudonia delunella. A Speckled Footman vied for this position but was our fifth record, the last was in 1937! Two Minor Shoulder-knots were our 4th and 5th records. Other new species for the year included Dunbar, Archer’s Dart, White Satin, Rustic, Common Emerald, Grey Pug and Catoptria falsella. There was another Langmaid’s Yellow Underwing and Catoptria verellus. There were eleven Bright Waves and a Rest Harrow.
A significant increase of the minimum to 15.5°C brought a huge increase in moths to 645 of 123 species, hence the delay in posting. Lots of local specialities are making an appearance. Last nights list included the following which were new for the year; Shore Wainscot, Dingy Shell, Rosy Wave, Beautiful Hook-tip, Ingrailed Clay, Browntail, Dioryctria abietella, Vitila biviella and Catoptria verellus.
A trap by the feeders held our first Langmaid’s Yellow Underwing of the year.
The temperature crept back up to 11.7°C and there was a slight rise in number of moths. There were 196 of 52 species. There was the first for the year of one of our local specialties – Pigmy Footman, plus Blackneck. A trap by the feeders added Double Square-spot and Evergestis limbata.
Two fresh and shiny Foresters was caught in the field.
The drop in temperature continued and there was a reduction to 154 moths of 35 species. Another Bird’s Wing was nice. There was only four species of ‘micro’ reflecting the cooler temperature.
A clearer sky and so a lower temperature of 10.5°C. The catch was also not helped by the intrusion of two sparrows into the trap. We have got away without this for several years. Maybe it reflects the shortage of suitable insect protein due to the earlier weather.
There were 260 moths of 55 species. The steady trickle of new species in the trap for the year continued. Riband Wave, Bird’s Wing, Broad-bordered Yellow Underwing, Anania perlucidalis, A. coronata and Clouded Brindle all fitted this category. There are less than ten records of the latter at SBBO. A late addition is the first Delicate of the year.
In the field our second record of the Nationally Scarce Nemophora fasciella was found in Middle Field, Cydia microgrammana was on Restharrow along the seafront, as was Platytes cerussella, and a Red-tipped Clearwing was seen well in Little Gully.
More cloud and a temperature of 14.6°C ensured a continued big improvement with 354 moths of 62 species. Pale-shouldered Brocade, Dusky Brocade and Beautiful China-mark were new for the year. A total of 36 Reddish Light Arches was impressive.
An Mv trap in the Elms yielded a different variety of moths including Shaded Broad-bar, Barred Red, Barred Straw, July Highflyer, Treble Brown Spot, and Mottled Beauty plus Vitula biviella, a recent pine colonist.
A thundery night with some rain resulted in 282 moths of 50 species. White-line Dart, Lesser Yellow Underwing and Small Yellow Wave were all new for the year. There were two of the latter which is a scarce species here with fewer than ten records. A Sycamore was also found during the day resting on the Warden’s window!
Still only 10.5°C but it was cloudy and there were 215 moths of 44 species. As well as some Bright Waves the first Rest Harrows for the year were out during the day.
More breezy and a bit cooler last night and there were only 123 moths of 39 species. A glimmer of hope that the hawk-moths might just be late emerging was provided by the first Privet and Elephant Hawk-moths of the year. There were also seven Diamondbacks, perhaps the tail end of the hordes that have been recorded further north.
Two hundred and forty seven moths of 47 species followed the recent improving trend. Clay was new for the year.
The improvement continued and there were 181 moths of 50 species in the car park trap. Light Arches, Common Footman and Uncertain were new for the year. Another trap by the Whitehouse produced about 110 species including a lot more micros. Barred Yellow, Slender Pug, V-pug, Currant Pug, Round-winged Muslin, Smoky Wainscot and L-album Wainscot were new for the.year.
All this provided a good variety for visitors to see. The best moth was provided by a visitor. We say bring in moths for identification or verification but it was a surprise to be handed a Concolorous which is a rare immigrant in this corner of the country.
The weather during the day was also good enough for the first Bright Waves to be recorded.
The improvement in the weather is starting slowly and the number of moths rose to 97 of 23 species. There were two Diamondbacks and a second generation Iron Prominent of note.
With the temperature down to 7.8°C and the breeze persisting it was not a total surprise that there were only 25 moths of nine species. Eleven of these were Heart and Darts.
Thankfully the weather is supposed to improve before our moth night on Saturday.
With the temperature still below 10°C there were 52 moths of 23 species. A fresh second generation Oblique-striped was the highlight. With most hawk-moths so scarce this year a Poplar Hawk-moth was of interest. There were single Silver Y’s and Diamondback.
With the temperature down to 7.9°C it was not surprising that there were only 80 moths of 19 species. Heart and Dart continues to dominate proceedings whilst Single-dotted Wave was new for the year.
An increase of 4°C produced an increase to 161 moths of 37 species. Purple Bar was new for the carpark trap and eleven Straw Dots indicated an emergence of these.
The trap could not be run the previous night due to the strength of the wind along with some heavy showers. This did provide some much needed relief to the dry conditions. Last night the temperature dropped to 8.5°C and there were only 95 moths of 22 species. This did include the second White Colon of the year.
Main interest was along the seafront where there were four Hummingbird Hawk-moths nectaring on the Red Valerian. A welcome addition in what so far has been a very poor year for hawk-moths.
It looks as if we are set for an unsettled period with cooler temperatures. A catch of 256 moths was therefore quite pleasing but there were only 38 species, the majority macros. Heart and Dart ruled the trap with 109 and there was the first Broad-barred White of the year to be in the trap.
Rain at the start of the night (the bone dry ground needed it) kept the temperature down to 8.8°C. Moth activity crept up a bit to 143 moths of 28 species. Heart and Dart remained the most common with 47 followed by 24 Vine’s Rustics. Despite the general paucity of Hawk-moths there was a Lime Hawk-moth which isn’t always annual here. There was also the third Chamomile Shark of the year.
Although the rain mostly stopped overnight and the cloud kept the temperature above 12°C there were only 101 moths of 28 species. This did include a Dark Sword-grass and a couple of Diamondbacks. A Bordered White was very nice as they are just about annual here and rarely in such good condition.
The moths seem to be taking heed of the threatened change in weather as the night time temperature dropped a bit. There were only 132 moth of 25 species nearly half were Heart and Darts. There was a late Muslin, which was smaller and darker. Pine Hawk-moth was new for the year.
Another warm night, 15.1°C, and a good catch of 392 moths of 82 species. Southern Wainscot and Pale Tussock were new for the year but it was the variety of moths that we do not get often which provided interest. This included the second Sand Dart of the year, an Orange Footman, Seraphim and two Small Seraphims. It is just as well there are plenty of Small Elephant Hawk Moths (14 last night) as there have been few other hawk moths so far.
The micro Platyedra subcinerea was only our third ever example.
The days continue hot, sunny and dry. The hoped for arrival of moths did not happen despite a southerly breeze and a minimum of 14.9°C. Yellow-barred Brindle was new for the year but more of note was another Fox Moth and two Hoary Footmen. A Shaded Pug appeared in an actinic in the Whitehouse.
Despite forecasts of a warm night the temperature dropped to 8.2°C and there were 172 moths of 32 species. Flame was the only new one for the year.
