October 31st

Slightly cooler but a few more moths with 61 of 20 species, this included 6 ‘micro’ species- not bad for this time of year here. A Dark Swordgrass, three Rush Veneers and a Diamond-back were of note.

October 30th

The previous night appears to have been it for the run of mild nights and the temperature was back down to 7°C . Moth numbers dropped accordingly but there were still a couple of Rush Veneers and the first Yellow-line Quaker of the autumn.

I forgot to mention the other thing noted yesterday which, although not actually moths I do not remember seeing before this late in the year, an emergence of ants under the trap.


October 29th

Overnight cloud ensured that at last we had a milder night (12°C) and a few more moths. Merveille du Jour was the pick of the moths, although annual it was getting a bit late. There were 86 moths of 24 species. Whether 13 Rush Veneers, three Rusty-dotted Pearls, a Diamondback and 12 Large Yellow Underwings were locally bred or fresh migrants is anybodies guess.

October 28th

Not sure what happened to the mild nights but it is still warmer than traditional autumn nights. 43 moths of 12 species were recorded including the first Feathered Thorn of the autumn. Four Rush Veneers could have been migrants or progeny of migrants.

October 27th

The overnight low dropped another degree but local moths were more active with 60 individuals of 18 species. Large Wainscot was most numerous ( perhaps helped by its super furry body ) with 22, there were also two L-album Wainscots.

October 26th

The hoped for mild night did not happen and the temperature dropped to 6.5°C. The moths responded accordingly with only 37 0f 11 species. A third of these were on the observatory wall some distance from the trap. There were 11 Large Wainscots and a Red-green Carpet.

October 24th

Thirty five moths of 11 species included 2 Black Rustics and a Vines Rustic. Was the latter yet another brood, due to the mild autumn, or a migrant?

October 23rd

Numbers have crept up slightly over the last two nights but there are no migrants. Nine Large Wainscots helped in the total of 53 moths of 13 species last night.

October 21st

A further slight decrease to 28 moths of 8 species. This did include a Turnip.

October 20th

Three degrees warmer but no Diana Ross. Thirty five moths of 12 species led by 13 Lunar Underwings. There was a Silver Y nectaring in the Haven field.

October 19th

A combination of stiffening NW wind, bright moon and a low of 5.6°C ensured that it was the smallest catch of the autumn with 12 moths of seven species.

October 18th

A very quiet night with just 26 moths of 11 species. Lunar Underwings beat Large Wainscots 8 v 6.

October 17th

A clearing sky led to it being much cooler than forecast, dropping to 6.4°C.This, combined with a very bright moon, dropped the catch to just 28 moths of 17 species. It did include the first November moth of the year and a Gem.

October 16th

Heavy showers ( themselves a novelty) meant there were only 23 moths of 12 species in the trap. This did include a Diamond-back and an Udea ferrugalis.

October 15th

More cloud last night and so a few more moths- up to 71 of 20 species. This included three Silver Ys, two Rush Veneers, aPearly Underwing and a Crocidosema plebejana. Seven Epiphyas postvitanas demonstrate the lack of frost so far as these will keep going until then.

October 14th

A degree or so warmer and so a very slight increase in moths. Lunar Underwings just beat Large Yellow Underwings 21 to 20. There was one Rush Veneer.

October 13th

The increasingly autumnal feeling was reflected in the catch of just 47 moths of 12 species. A Turnip was suspiciously fresh to be an in-blown migrant.

October 12th

Once again there were showers but the temperature was 2°C higher and there were a few more moths totalling 99 of 21 species. The majority were the usual autumn suspects, Lunar Underwing, Large Wainscot and Black Rustic but there was one Silver Y and one Rush Veneer.

October 11th

Heavy showers interspersed with clear moonlit spells meant the trap was quiet with only 67 moths of 17 species. Only Lunar Underwing made it into double figures with 27. There was one Rush Veneer.

October 10th

Again the temperature fell to below 7° C but there were 146 moths of 26 species.We caught several individuals of moth species that would have once been thought of as migrants but whose status has now apparently changed to include regular breeding. These were:Rush Veneer 3, Udea ferrugalis 1, Whitepoint 1, Delicate 1, Diamondback 1 and Cypress Carpet 2.


October 9th

Considering the temperature dropped a bit lower, to 7°C, and there were some showers a catch of 173 moths of 28 species was suprisingly good. There were seven Rush Veneers, a Scarce Bordered Straw, a Dark Swordgrass and a Crocidosema plebjana. Dark Chestnut was new for the autumn.

October 8th

Although the temperature dropped to 8.7°C cloud helped the trap to be suprisingly busy with 252 moths of 24 species. Migrants included two Silver Ys, four Rush Veneers, two Udea ferrugalis and a Diamond-back. Twenty-four Large wainscots and eight Deep-brown Darts were also notable.

October 7th

63 moths again but only 10 species and no migrants. Lunar underwing was the most common with 35.

October 6th

The easterly strengthened and the temperature dropped a degree or so resulting in 63 moths of 13 species. This did include another Convolvulous Hawk Moth and the first Barred Sallow of the autumn.

October 5th

Due to the strength of the easterly I did not approach the moth trap with a great deal of hope. However amongst 117 moths of 18 species there were five Diamond-backs and singles of Scarce Bordered Straw, Convolvulous Hawk, Pearly Underwing and Rush Veneer.

October 4th

The breeze and some cloud helped keep the night warmer but the number of moths increased by only two. This did include a Delicate and a Diamondback.

October 3rd

The coolest night of the autumn so far,down to 4.8°C, but the trap was in before the frost started forming. There were 144 moths of 20 species. Green-brindled Crescent was new for the year and there was yet another Dusky-lemon Sallow. Rush Veneers were down to three.

October 2nd

After a night off the trap was back in action but in a sheltered spot due to the heavy showers which did not clear until after dark. The catch was typically autumnal with 80 moths of 13 species. Setaceous Hebrew Character was finally deposed from the top of the leader board by Lunar Underwings ( 41 ), there were also 15 Rush Veneers
