A Very Mothy June

Judging by all the exclamation marks and 'best ever' this and that comments on social media, I am guessing that 2025 has so far been an exceptionally rewarding year for moth folk. My very limited experience suggests likewise. My fitful efforts last year yielded 20 new species for the garden (NFG) whereas the first six months of 2025 have already increased the garden list by 38, including three last night...

NFG

Lunar-spotted Pinion. Not common locally - just six Bridport area records on the Living Record map - and wasn't on my radar. Initially I had no idea what it was.

Marbled White Spot. Caught one in our son's Lyme Regis garden last year, so I recognised it. Probably a bit overdue. Certainly there are several Bridport records.

Marbled White Spot, side view.

Ribwort Stilt Aspilapteryx tringipennella. I do like the stilt moths, so it was pleasing to see a new one. Discovered as I was releasing the night's catch this morning. My bleary eyes had failed to spot this tiny sliver of a moth when processing the trap first thing.

There were also a few nice migrants. I wonder how much longer they'll be around, and when/whether we will have another arrival...

 

Migrants

In addition to the migrants depicted below, the last two nights have also produced two or three Diamond-backs and European Corn-borers...

Bordered Straw #6 for 2025. The previous three seasons have produced just four, all in 2022.

Rusty-dot Pearl Udea ferrugalis. A regular here, but I don't think we've had any others so far this year.

First Dark Sword-grass of 2025, trapped Sunday night. A regular migrant, though we don't see them often. Maybe four or five a year?

The fourth Small Marbled of 2025. Without doubt an exceptional influx of this species. Many long-time moth recorders are getting their first for the garden.

So that leaves the also-rans. Last night especially was another busy trap, with quality in spades...

 

Also-rans

First Canary-shouldered Thorn of the year last night. A beautiful moth.

Canary-shouldered Thorn, alternative view.

First Marbled Green of 2025. Despite the name, they're not always green.

The Coronet is fairly common here, but the deep, dark greens and purples on this individual made it well worth a snap.

Eyed Hawk-moth. Just wonderful! I think this is our third of the year. Which is roughly what we usually get.

The garden's second Slender Brindle. And this time I managed not to discard it with the Common Rustic aggs.

Another Sunday night moth - our second Mullein Wave. Not uncommon locally.

Hoary Tortrix Eucosma cana. Just because.

Thistle Marble Lobesia abscisana. Not loads of records locally (think I've had three now) so a nice catch.

Gold Triangle Hypsopygia costalis is a little beauty. It occasionally rests with its wings open, so I was very chuffed to get this pic, despite the plastic pot lid showing well!

Large Tabby Aglossa pinguinalis x2. Not especially common in Dorset, with just three Bridport area records on the Living Record map currently. We have had about six now, so I'm not sure what the attraction is. The larvae have sheep poo on their menu, but it definitely is not that...

Water Veneer Acentra ephemerella. The scientific name is very appropriate, because ephemeral they certainly are. We've had this species several times - occasionally in numbers - and very few of them last the night. This one was moribund.

Back when I was just a birder, June was a killer month. Now that moths are on the agenda, June is still a killer month, but for a different reason. I am currently reading a book about sleep, and if I was to limit myself to one take-away point so far, it is this: DO NOT compromise on sleep, because doing so will give you all sorts of health issues and shorten your life.

So, one more trap. Then a few nights off, and a lot of sle-e-e-e-ep... 

Nine NFG

2024 was technically my third season of mothing (though I did start mid-way through 2022) and produced exactly 20 new species for the garden, or NFG. To be fair, my efforts were a bit sporadic, but even so, I was happy enough with 20. This year has been similarly hit and miss on the effort front, but the rewards on another level! Last Saturday night alone produced five NFG; Thursday night, one of two NFG was a ridiculous rarity; Friday night, five more NFG...

Which brings us to last night - Saturday - which produced an astonishing NINE new moths!

I am glad I no longer count stuff, because frankly I would not be able to cope at the moment. It is more than time-consuming enough just potting and photographing the highlights. Anyway, here is an illustrated summary of last night's catch...

Migrants

No migrant NFGs as far as I could tell, but some proper quality even so...

Our third Small Marbled.

Pearly Underwing x2. There is just one previous garden record, from September 2022.

Pearly Underwing, showing the grey, tufty ridge along the thorax.

Bordered Straw #5 for the year.

In addition there were two or three Diamond-backs and at least one European Corn-borer, so the night was very productive migrant-wise.

 

NFGs  

Thankfully I managed pics of all nine...

Mottled Beauty. In three years I have checked hundreds and hundreds of Willow Beauties in case they were something other than Willow Beauty, but they never have been. Until now. Finally!

Purple Clay. A bit knackered, but who cares? Nice to see a hint of purple on its wings.

Cypress Carpet

Size-wise this Gromwell Ermine Ethmia dodecea is no different to the hundreds of indeterminate ermines that have inundated the garden recently, but those fat spots nail it. Not rare or anything, but satisfying all the same.

Bracken Gall Moth Monochroa cytisella

Not quite the photo I would have liked of this rather smart Pine Knot-horn Dioryctria abietella, but like many pyralids it was a bit of a 'mare in the studio.

Barred Hook-tip

Gorse Wanderer Brachmia blandella, presumably having wandered from some gorse.

Cock's-foot Miner Elachista atricomella. This moth has a number of look-alikes, but hopefully I've got the ID correct. Anyway, it's common enough.

None of the NFG moths appear to be particularly uncommon locally, so most are just a bit overdue I guess. In fact the scarcest non-migrant last night was a species I first encountered about three weeks into my mothing journey, in June 2022. At the time I managed a pot-shot only. This morning I made up for that...

 

Quality

Shaded Pug

Shaded Pug is not common in Dorset, though the Living Record map suggests there are hot-spots here and there. Bridport is not one of them, and there are no dots other than ours.

I potted this little beauty off the trap vanes late last night. I wonder whether it would have found its way inside had I not been out there... 

Incidentally, the right hind-wing is malformed, not damaged.

 

Random

There were lots of other smart moths and a bit of interesting bycatch, so a few more pics...

Giant Lacewing Osmylus fulvicephalus. What a beast!

Pied Rabbit Moth Ypsolopha sequella. We get a few each year of this quirky micro.

Fleabane Drab Phtheochroa inopiana. Our third or fourth this year I think, but the first I've managed to photograph. Slippery blighters! Not especially common locally.

Cream-bordered Green Pea. One of those 'two or three a year' moths, but there were two in last night's catch.

Blair's Mocha. The first for a while.

Immaculate Bordered Beauty. Caught two last night, though only had one or two a year previously.

Vapourer. Another moth encountered infrequently.

So, following that ridiculously prolific session I did wonder about the wisdom of doing it all again tonight, with the inevitable consequences upon real life and my ability to function as a human...

Anyway, the trap is lit.

Another Five

It is currently 22:20 on Saturday, 28th June 2025 and already there is a potted Blair's Mocha in the fridge, next to the yoghurts and beer. I foresee mothy riches. Last night was another good one. Good one? Excellent one! Five new moths for me, and all sorts of other quality. If I don't get this stuff blogged pronto, there is going to be an overwhelming backlog. So...

Grey Arches. Seems quite common, but new for me.

True Lover's Knot. This beautiful little moth is a heathland specialist which feeds on heather, so no surprise that it is not particularly common locally and only our second.

Wax Moth is not that numerous locally, but we get a few each year.

Dingy Shears is the second new moth for me, and again, not especially common locally.

Cloaked Minor is a subtle little thing. We get a handful or so each year.

Long-winged Pearl Anania lancealis is a 'one or two a year' species.

Beautiful Golden Y. Common enough, but only one previous record for the garden. Despite absence of thoracic tuft, and some rough edges, still a stunning moth.

The garden's first Small Ranunculus. Probably last night's highlight. There are currently very few Dorset records, though it appears to be heading this way.

Sandy Carpet. We've not had many. This species has been a nightmare to photograph, and I ended up chasing this one all over the garden after it escaped the studio.

Hoary Tortrix Eucosma cana is common enough, and we've had a handful this year so far.

First Rush Veneer Nomophila noctuella of the year. A common migrant, though when they are here in numbers I tend to kick more out of the coastal vegetation than we ever get in the trap.

One of last night's highlights, our second migrant Small Marbled. A recent big arrival it seems, with this species making the NFG list for a lot of moth folk I follow on Bluesky.

Small Marbled again.

Another NFG, Honeysuckle Grey Athrips mouffetella seems to be uncommon in Dorset, with just a couple of Bridport area records on the Living Record map.

Our second Large Emerald. I'd forgotten how enormous they are!

Large Emerald. A bigger acreage of green than any other UK moth I'll bet.

Two very different Oak Nycteolines, our first of the season. Not uncommon, but we only get a couple or so per year normally.

Lobster Moth. Just one previous garden record.

There are four NFG moths in the gallery above. Unfortunately the fifth escaped pre-photography. This was especially annoying because it was quite a decent migrant: Tufted Oak Knot-horn Acrobasis tumidana. It was also very fresh, and would have made for a nice pic. I can only hope that the current cloud of migrants whirling around the country just now might drop me another one soon...
