Wicken Fen - Field Trip - 23rd May

I was invited to trap at Wicken Fen for a mini blitz of two areas at once, Adventurer's Fen to the South-west of Wicken Fen, and several trappers also around Sedge Fen and visitors area.

I was just to the south of the visitor centre, positioned with 4 traps primed and ready for the arrival of moths.

I did a bit of dusking but there were very few moths that I saw flying, as it was fairly breezy at time. Tapping a few trees and bushes dislodged a couple of specimens to the back of the net, but the night soon closed in and the traps were on.

Two of the traps were a bit exposed and did not fare very well, I opted to close down the actinic trap as it was just full of flies and only a couple of moths seemed interested.

But the 125w clear near the car park area did very well for variety, even better though was the trap that never lets me down, the 250w clear robbo.

Most of the nights moths and species came to this lamp and by the time I packed up at 2am I had amassed an incredible 157 species, for May this was very pleasing indeed.

 

Highlights included several Dentated Pug, one was pretty fresh and good to see, as all my previous ones have been battered.

15 Poplar Hawk-moth was a nightly record for me. 

 

There were surprises of fresh Clouded Drab & Powdered Quaker, both are my latest ever records, and looked particularly funny flying alongside Elephant Hawk-moths! 

 

There were also a few migrants present including one Delicate and five Small Mottled Willows.

Best moth of the night were two examples of the tiny Vine Moth (Eupoecilia ambiguella) sadly both a bit worn.

A nice selection of moths and good to get together with a few other fellow trappers.

Another great catch of moths

A warm day of 28 degrees yesterday and the night held up nicely until after midnight where it went a little damp and cool.

Arriving home at 2.30am from Wicken Fen, I decided to go through the trap and turn it off so I could have a bit of extra sleep. 

The temperature dropped to 14 degrees, still very good for the time of year.

 

As a result there were probably still around 50 species in and around the trap, but I didn't count them all this time as I was too pooped, instead just potting up all the new ones. 

I managed to find 11, but probably missed a few more through tired eyes.

Brown Silver-line was the best moth and only my 2nd garden record after the first last year.

Dog's Tooth was nice to see and in fantastic condition too.

Micros dazzled with a large metallic green Coleophora. Expecting amethystinella, upon checking for the orange eyes, I was pleased to identify it as trifoli (On size and no range eyes). This isn't a common moth here, opposed to the regular alcyonipennella/frishella.

The first migrant Udea ferrugalis also turned up, alongside 3 Ostrinia nubilalis. No massively rare migrant moths but could there be one tonight? Who knows... only the moth gods.

More of the same!

A super repeat of yesterday night here, with a similar 75 species recorded overnight.

19 moths were new for the year, making it nearly 50 new ones over the past two night, unprecedented here for my garden, and it's only May! 

The days are warming a degree or two each day as we go towards a scorching bank holiday Monday.

Last night the minimum temperature in my garden was 19.4c at 4:30am, crazy.

I woke up at around 3:45am to go through the trap and was pleasantly surprised by how busy it was, the trap and walls were full of micro moths, and the constant buzzing from Cockchafer's was something i'm only used to from wasps, their must have been 15 of the blighter's.. well.. at least they don't eat the moths I suppose!

Highlights were 2 lovely Shark moths, one really well marked and streaky, a huge Privet Hawk-moth which was too lively for a photo, and countless micros that are featured in the full list below.

Out tonight so it'll be a late one!

Species overload!

It was really busy in my garden last night, not masses of numbers but as always, the species delivered.

The weather was calm and mild and with a hint of cloud, although this won't matter as we progress into the weekend, as the air mass we are currently importing is so mild that it is replacing any cooled down air that we lose out into the atmosphere.

I started netting at around 8pm and packed it in just after 9, netting around 40 moths of 15 species, several of them new, but dominated by Mompha subbistrigella and various Dichrorampha & Bryotropha species, the best was a pair of stunning Chrysoesthia drurella.

The list overnight went on and on, and I nearly ran out of pots when I woke up at 4am.

I make it 73 species which must be my highest May catch so far. 

30 species were new for the year, and a further 2 possibly 3 are new for the garden.

Satin Wave was a new garden macro moth, a moth I am familiar with from Herts and Essex, and a leaf mine from Hawthorn emerged revealing my first ever adult Stigmella crataegella.

Even better, a tiny grey Elachista was potted up and photographed to reveal the possibility of it being Elachista bedellella, a moth that hasn'e been seen in the county for 126 years! I've retained it for dissection.

 

There were too many other highlights to list, so i'll let the list below do the talking.

 

Never rains it pours in this country.

 

We go again tonight....

Nearly there!

We were just on the edge of some really mild nights to come on Wednesday night, with lows of 13 degrees and 15c at midnight, it was still pretty good.

But from now on we are looking at +16c at midnight which is excellent for micro moths in particular. 

 

A fair haul on Wednesday night in my garden, but I expected a few more given the conditions, although the wind was still a bit gusty after dark for a few hours.

 

Green Pug was the sole new macro moth species for the year, this was backed up by two common micro moths.

 

A grotty Elachista was retained which will probably turn out to be atricomella.

 

Calm before the storm? I think so.

Blowing a hooley

It was extremely windy last night here in my village but warm with it, not dropping below 13 degrees and so I duly popped the trap on.

I had to lay the sheets across the patio to keep to dry for fear of any rain, and i'm glad I did as we did have a downpour at 11pm.

Despite this there were 27 species recorded by dawn and 7 of which were new.

 

Highlights included Alder Moth, Campion and a worn Aspilapteryx tringipennella

The weather is certainly feeling more humid as of today, but we've still got a nagging wind.

Wet and warmer

The nights start to improve now as we head towards a potential heatwave starting around Thursday, a mildish night with lows of 10 degrees last night, but rather damp although the rain must have not come to much in the end.

45 moths of 25 species was a respectable return given the conditions.

Highlights included year first macros of Blood-vein and two very different Large Yellow Underwings, and a very late (possibly my latest ever) Clouded Drab.

Seconds for the year of May Highflyer and Poplar Kitten were also most welcome. 

Micros picked up as well, with none present on the last two outings, to 5 species seen last night.

Come on warm weather, we've waited long enough!
