July 2025 - trip to UK (day 3)
/Elephant Hawk-moth - Shotesham, 26 Jul 25
The moth trap had been set in the village garden the night before, and in the morning, there was a literal smorgasbord of tasty morsels to pick through, many of which were new for me. It had been good weather conditions for moths, so the trap was pretty full, and the highlight for me was the superb pink-and-khaki beast that is Elephant Hawk-moth, a species I had been most keen to see. It does occur from time to time in Guernsey traps but never in mine.

One of the nice things about the trap-emptying was that I had not really researched what species were likely to be found, so there were many nice surprises. The second-most impressive beast to me was the gold-dipped female Ghost Swift that was pulled out. As this does not occur in Guernsey I had forgotten that only the males were white.

I managed a total of eleven new species of moth from the trap - the above two, plus Maple Pug, Brown-line Bright-eye, Pandemis corylana, Apotomis betuletana, Evergetis pallidata, Ypsolopha scabrella, Morophaga chorogella, Recurvaria leucatella, and Catoptria falsella - not a bad haul. Some of these are pictured below.
Evergestis pallidata - Shotesham, 26 Jul 25
Pandemis corylana - Shotesham, 26 Jul 25
Apotomis betuletana - Shotesham, 26 Jul 25
Ypsolopha scabrella - Shotesham, 26 Jul 25
Recurvaria leucatella - Shotesham, 26 Jul 25
Ethmia quadrilella - Shotesham, 26 Jul 25 - would have been a new species if we hadn’t seen one the previous evening
Pale Prominent - Shotesham, 26 Jul 25 - not new, but I’d only seen one previously, in the same place many years ago
Green Drake mayfly - Shotesham, 26 Jul 25 - also in the trap were a few of these impressive beasts which I didn’t know existed! I had only ever seen small, dull mayflies before, but this was a whopper
Mystacides longicaudis caddis-fly - Shotesham, 26 Jul 25 - a distinctive caddis, also a new species
That wasn’t quite it though for the moths that night, as I had noticed a tiny, unobtrusive tortrix moth that I didn’t immediately recognise and potted it up to look at later. Through the hand lens, the distinctive feature was a series of 4 pale lines on the ‘top’ of the moth (the dorsum). This is not a common feature and a moth which has this is typically Grapholita compositella. However, this did not seem right at all, that species being black, grey and bright white, but this was a warm brown colour. I was aware that a few similar small tortrices do have smudgy, less distinct markings in that area of the wing, but after a flick through the book I still couldn’t place it. I then had a tiny spark in my brain about something that I’d read in Atropos just a few weeks ago, about a new species which had occurred in the UK recently which also had these 4 lines on the wing. Some internetting ensued and the species in question was Grapholita delineana - it looked good but, without detailed information to hand, I would have to retain the specimen to confirm when I got home.
Grapholita delineana - Shotesham, 25Jul25
To cut a long story short, back at home, I confirmed the ID by dissection and it was indeed Grapholita delineana, only the second location for Britain! Not too shabby, the ID features are shown in the graphic below. The first record was only in July 2024, not too far away in Lowestoft, where there has apparently been multiple records since, indicating that it is breeding nearby. It is originally an east-Asian species but has apparently been spreading widely round the world. It is also known as “Hemp Tortrix” as it commonly feeds off Cannabis plants. However, unless there is a clandestine “herb farm” somewhere in this sleepy Norfolk village, it is no doubt feeding off Hop, another food plant. I was certainly not expecting us to find a second for Britain on our BUBO weekend!
After the leisurely morning looking through the trap, and a couple of hours taken up by visiting family/doing a park-run, around lunchtime we headed for a superb nature reserve called Wheatfen on the edge of the Norfolk Broads. It was so peaceful and quiet there, I can’t recommend it enough. Lots of boardwalks and paths right through the reedbed and fen habitat, with lots of trees and some ponds, it was excellent and full of wildlife. Unfortunately, the weather was a bit dull for flying beasties to be out and about, but we saw lots of interesting things.

One of my key targets here was Silver-washed Fritillary, a species that I have managed to avoid all these years. Even though it was quite dull, we had a little sunny spell along the first path which brought out quite a few butterflies, including a single SWF swooping across the reed-tops, back and forth at quite a rate. It was difficult to pin down when it landed but I managed one distant shot as it fed on a Hemp Agrimony flower.
Silver-washed Fritillary - Wheatfen, 26 Jul 25
The best lepidopteran species which we found was Balsam Carpet which we finally found after bashing many an Orange Balsam plant growing along the ditches. It was a touch tatty, and we contemplated other species, but we were satisfied in the end.
Balsam Carpet - Wheatfen, 26 Jul 25
I had a total of 20 new species at the reserve many of which were marshland specialists. Various species of plants I ticked off included Skullcap, Small Teasel, Small Balsam, Green Figwort, Fat Duckweed (“El Gordo!”) and the huge Broad-leaved Ragwort. Of the invertebrates identified Water Ladybird was notable and we netted an example of the scarce Skullcap-feeding sawfly, Athalia scutellariae.

It had been threatening to do so all afternoon, and finally, just before 4pm, the heavens opened up big-style, and we were not close to the car at all. Of course, I was only wearing a t-shirt since it was a warm day, and I was like the proverbial soggy rodent by the time I got to the car park. Luckily, I had actually brought a different top that I could change into as we found shelter from the deluge. And it was a deluge indeed, the lanes and tracks quickly filling up. We sat out the rain in the totally rammed Ferry House pub in Surlingham, where we ate an enjoyable bar meal serenaded by quite possibly the worst musical turn I’ve ever heard in public.

After the rain finally subsided somewhat, we waded across the car park and headed on out again. Andy had arranged a moth-trapping session with the warden at Strumpshaw Fen nature reserve. We arrived well-before dusk and so we had a wander round part of the reserve first. It was not raining any more, but the air was heavy with damp, and the light was poor. We spent a bit of time in one of the hides enjoying a family of Marsh Harriers calling to each other across the fen. A single bedraggled juvenile Bearded Tit spent a long time out in the open on the other side of the pond. We heard a few more though along the path.

We wandered back to the reserve centre and met up with Ben, the warden. The first thing he showed us was a rare species of fungus which had appeared on a log behind the cottages - Artomyces pyxidatus, which seems to have a few common names Crown-tipped or Candelabra Coral Fungus. This species apparently has recently been seen at a just few sites in the UK after no records for over 100 years, and it is an impressive fungus indeed.
Artomyces pyxidatus - Strumpshaw, 26 Jul 25
We spent the rest of the evening helping to set up a few of the traps. We had about five traps - a few by the reedbeds and a couple in the wooded areas. It felt a warm night but there was a lot of water everywhere and we weren’t expecting lots of micros at least but the macros should be flying fine. Whilst we were waiting for darkness, we watched a roost of Soprano Pipistrelle bats emerge one by one from a barn, heading off into the gloom. I only know that they were Sopranos as it was a known colony, but a tick for me nonetheless.
Strumpshaw, 26 Jul 25
The reedbed traps drew quite a few reedbed specialists from across the marsh, including multiple wainscots - Brown-veined, Twin-spotted, Webb’s, Southern and White-point - as well as the reedbed crambids Calamatropha paludella and Donicaula forficella (the latter a tick for me). More impressive were the huge female Drinkers which were quite common and never refused a chance to smash into your face on their way into the light. Another reedbed specialist was the Reed Dagger which we saw as a larva first, with an orange-spotted caterpillar chomping a reed blade right next to the MV, and then an adult on the outside of the trap. Not a wainscot but a wainscot lookalike noctuid.
Drinker - Strumpshaw, 26 Jul 25 - not technically a tick, but I had only seen larvae previously

We saw many more species of as we toured the traps, and I had 8 new moths that night. The other new species were Iron Prominent, Large Emerald, Crescent, Alder Kitten, Svensson’s Copper Underwing, Apotomis turbidana, as well as a few species I’ve rarely seen like Sallow Kitten and Black Arches.
Iron prominent - Strumpshaw, 26 Jul 25
Large Emerald - Strumpshaw, 26 Jul 25 - what a species! Instantly one of my favourite moths.
Alder Kitten - Strumpshaw, 26 Jul 25
Sallow Kitten - Strumpshaw, 26 Jul 25
We picked up a few other species by the lights including a fabulous Oak Bush-cricket, a species I’d never seen before. We also heard a Bittern call as it went overhead, and I managed to get the sound recorder out in time. After a while, our enthusiasm was overtaken by weariness, and we packed up and drove home. Many thanks to Ben for sorting out the trapping session.
