Chippenham Fen - Field Trip - 28th July

A made an overdue trip to Chippenham Fen last Tuesday night, I'm not sure where the 5 weeks went between this visit and the last, but the warm weather has made time fly very quickly indeed.

Another warm day, well warm week infact!

I arrived just as it was getting dark and it was a quick setup and lights on at around 9.20pm, the nights are certainly drawing in fast now, even when its a clear sky.

There were variable amounts of cloud, clearwing by packing up time at 2am. A big bright moon was also present, but quite low in the sky so no issue whatsoever. 

212 species were recorded over the 4 lights that were ran. The poorest trap was the 30w led, it was so bad that I canned it at midnight. This is really odd as this trap did very well at two other sites recently.

Both the 125w MV in the field edge and the 250w by the barn faired very well indeed, and it was hard keeping up with the species coming in, although numbers weren't as large as I had hoped and the summer peak has definitely subsided now. 

Amongst all of the moving moths were two stars, a first for me Great Brocade, and another new moth in the shape of a small geometer, a Rest Harrow.

The latter I presume is a wanderer from coastal populations, but the former could have well been a genuine migrant, who knows!

 

Other gems included (not a Gem sadly) 3x Vestal, Apodia martinii (name change alert), lots of Dingy Shell's, 2x Elachista bedellella, Golden-rod Pug, Lyonetia prunifoliella & Square-spotted Clay.

 

A right result for the end of July.

New ones calming down now, a night of seconds

Just 2 new species for the year graced my trap on Tuesday night, as we calm down now with species diversity.

Though there were still around 40 species present and some pleasing moths paid their second visit of the year, they were Acleris cristana, Bordered Straw, Tawny-barred Angle and Yponomeuta plumbella.

 

The Bordered Straw and Yponomeuta plumbella were both new species only this year, so it was good to get a second of each.

 

Best moth of the night was the Heather wandering True Lover's Knot, what a spectacular name for a moth! 

Big winners are still Marbled Clover, Nutmeg and Yponomeuta of various species.

It stays warm and dry, but we did get some rain finally!

Cranwich Camp - Field Trip - 25th July

Leslie and I made a drive up to nearby Norfolk at the weekend to run some traps on the edge of Cranwich Heath.

An interesting area of mainly pine woodland with an interesting array of  under-storey and with fields of wildflowers it really is a rather unspoilt area that usually throws up some lovely species, some that just don't feature here in Cambs.

 

We set-up 4 traps spread around and all out of sight of one another. 

It had been a breezy but very warm day with highs of 30 degrees, the wind was set to abate by night fall.

 

Unfortunately this was not the case, and a couple of hours in, it got stronger! 2 traps were packed up that were being rattled by the strong breeze.

The trap exposed to the west wind was the worst, with only a handful of moths inside after 2 hours!

The larger 250w trap faired so much better, and the little led trap did ok too, so we ran them in tandem until 1am, then followed by a slow pack up.  

 

Some great moths were seen, Clouded Magpie, Dotted Clay, Sharp-angled Carpet and several scarce micros as well.  

 

There were two new micro moths potted up that are new for my records, Chionodes distinctella & Scrobipalpa artemisiella, the latter quite scarce indeed and separated by its tiny size.  

 

Two stunning Geos were great to get photographs of as well, the Spruce Carpet was a particularly bold marked example. 

 

Despite the challenging conditions and the insane amounts of ants (flying and crawling varieties) we amassed 185 species.

Warm and busy nights

Some really warm nights are now upon us, although Sunday night I had a much needed rest from it all, as the temperature fell away to 14 degrees so not ideal.

Come Monday and it was another warm night with minimums of 17 degrees, if a little breezy at times, but with 20 degrees at midnight it was worth running the trap once more.

A good selection of species was observed and some scarcer second records of the year for certain species of micro moths.

There were 3 new ones for the year, two of them were tiny specks of colourful dust, Phyllocnistis saligna & Phyllonorycter stettinensis, Willow and Alder feeders respectively.  

The Phyllonorycter stettinensis was new for the garden, the 28th new micro moth this year.

 

The third new species for the year was the lovely Evergestis extimalis. 

Scythris limbella was good to see again, and since I’ve had a further 2 last night so that is 4 for the year so far. 

A third Cydia amplana was good to record also, a once scarce immigrant to our shores, it seems quite regular this year for a lot of southern folk.

More good mothing conditions on the way!

Mega Migrant!

The only new species for the year on Saturday night was just a casual Eastern Bordered Straw :o what a moth, one I was really hoping for (This or Ni Moth).

I found it by sheer chance. I got back home after a field trip at 2.30am, and started to pack up the trap. It had been very breezy all night and there were only a few moths which was disappointing considering it was still 18 degrees.

I had already potted a mint Lychnis for a photograph the next day, not new for year but a cracking example, then as I reached over to unplug the trap, there it was! Sorry Lychnis but you had to go... 

 

Now that we've had a little bit of rain last night and this morning, I would hope that numbers might pick up again? We shall see.

Another new garden moth

Another good catch on Friday night, still around 40 species so not too bad at all. 

Big hitters are currently Turnip Moth, Nutmeg, Common Wainscot and unbelievably Small Mottled Willow, which is still up there with the common moths! If you asked me last year that Small Mottled Willows will become common next year, I would have laughed!

As with mothing, it only really takes one moth to make lighting up worthwhile.

Yponomeuta plumbella was a new species for the garden, a tiny little white moth picked out amongst the 10's of other Yponomeuta species. This is probably the main reason why it stays an uncommon species, as apart from the dark dots on each wing, they aren't that easy to tell apart, especially at night.

The first July record of Square-spot Rustic was also noteworthy.

The rain was coming, but just how much were we going to get?

Migrant micros reach my garden

Some decent migrant micro moths reached my humble abode on Thursday night, with 2x Cydia amplana which are only the 2nd & 3rd garden records, and an extremely tiny tortrix, Crocidosema plebejana which is new for my garden and was very lively indeed, almost losing it once amongst the stubble in the garden.

The two Cydia's were remarkably different and great to see the colour variation that can occur.

Two scarcer micros for my garden also showed their faces, Monopis weaverella & Pandemis corylana. I get stacks of Monopis laevigella, but struggle to tick the other off every year.

Then there is corylana, the Chequered Fruit-tree Tortrix that sometimes doesn't even turn up in a year! Very strange for two common moths.

Not to leave out the macros, luckily one made it on the year list, a Small Rufous.

Warm but some nights have been a little cooler towards the back end of the week.

Back to back Clyps

Last night it was a little warmer and calmer, but with a slight breeze still coming from the east coast.

Lows of 15.8c was decent enough for the time of year and highs of around 26 degrees during the daytime.

Less species than the previous night, but some more quality.

Firstly my 2nd garden record of Bordered Straw was sitting proudly on the underside of one of my external egg trays, more than enough reason to always put egg trays around the outside of your trap! If you don't currently do it... do it tonight!

The last one I saw in 2022, a sporadic migrant that has good years and bad years, much like its congener the Scarce Bordered Straw.

 

Tawny-speckled Pug was the 2nd new for year species, and staying on the pug front, a White-spotted was nice to see, having had a 3 month hiatus. 

Coleophora clypeiferella was recorded again! 2 in 2 nights and pretty special to say the least, specimen checked to confirm.

Other good returning micros included Dioryctria simplicella & Nephopterix angustella.
