Description


A diary of my mothing activity covering highlights and photos from my moth trapping activities. Mainly Norfolk (UK), occasionally beyond. I may mention other wildlife sightings here, especially insects, but for birds see my birding diary.

Review of 2019 and 2020 - Moths: Plumes (Pterophoridae) (part 2), Lance-wings (Epermeniidae) and Metal-marks (Choreutidae)

PLUME MOTHS (PTEROPHORIDAE) (continued)


Citron Plume Hellinsia carphodactyla
- One at Bintree Wood on 13th June 2020.  This is the first one I've caught away from the Brecks and gives me hope that I might get one here or at the meadows sometime.  Also shown below is one I confirmed for Geoff Turner at Weybourne in 2019.

Mugwort Plume Hellinsia lienigianus - One at the meadows on 30th June 2019.  I've recorded this species in the garden on 2 occasions, both in 2017.

Hemp-agrimony Plume Adaina microdactyla - None.  I've only recorded this species at home once, in 2015.


Common Plume Emmelina monodactyla - At least 123 at home between 5th March and 12th October 2019, but not counted on 4 nights so perhaps more.  That's my best year here so far, with numbers increasing (if only slightly) each year since I arrived - until 2020 when there were only 91 between 5th April and 22nd October.  Also recorded next door, at the allotment, at the meadows, at Lyng Easthaugh, Whitwell Street, Hellesdon and in Cornwall.

-----------------------------------



FALSE-FEATHERS (SCHRECKENSTEINIIDAE)


Bramble False-feather Schreckensteinia festaliella - None.  I've never recorded this unique species locally (only at Frost's Common in 2017) but I see no reason why it shouldn't be present round here.




-----------------------------------



LANCE-WINGS (EPERMENIIDAE)


Yellow-spotted Lance-wing Phaulernis fulviguttella - None.  I've only recorded this twice, both at West Raynham in the daytime in 2013.  It's a scarce species but it may well occur locally.  Probably more chance of finding this one at the meadows than in my garden.


Scale-tooth Lance-wing Phaulernis dentella - On 21st June 2019 I netted a small worn moth along the track at the meadows in identical circumstances and in almost exactly the same place as I netted my first and only confirmed dentella on 6th June 2018.  The shape of the moth put me in mind of the 2018 record but the distinctive markings of dentella could not be discerned, either because it was too worn or because they weren't there in the first place.  I imagined gen detting would resolve it, and in time it may yet, but the problem for now is that I cannot find any reference material to compare it to.  It was a female and there are no images of female genitalia of Phaulernis dentella on the Dissection Group website, nor on any of the other websites that often have such things, nor in any of my books.  I've asked around but can't find anyone who has any such images.  Part of the problem is that it's a nationally scarce moth that is quite rare outside of Norfolk (although it doesn't seem to be restricted to particularly unusual habitats within Norfolk).  The genitalia do look very similar to female Phaulernis fulviguttella, but not identical to the Dissection Group image of that species, leading me to conclude that it may well be dentella.  However, some of the Epermenia species have similar genitalia too (indeed the non-Norfolk Epermenia insecurella is arguably a closer match than Phaulernis fulviguttella) so I'm not sure.  I think most of the Epermenia have longer narrower wings so I feel it is most likely Phaulernis dentella, but although I hope one day to resolve this, for now I've hit a dead end.

Garden Lance-wing Epermenia chaerophylllella - One in the garden trap on 4th July 2019.  None in 2020.  I record 1-2 most years but 2020 wasn't my first blank; it's one of the few species I used to see more often at Bawdeswell than I do here.

Large Lance-wing Epermenia falciformis - 2 in the garden and one at the meadows between 17th and 27th August 2019 but none in 2020.  I had 2 here in 2018 but prior to that I'd only one here since arriving in August 2014.

METAL-MARKS (CHOREUTIDAE)


Common Nettle-tap Anthophila fabriciana - None at home in 2019 or 2020, my first full years living here witout finding any in my garden.  2019 seemed to be a poor year for this sometimes-abundant species - I only recorded singles at the meadows on 4 dates between 20th April and 21st June and then 2 on 11th September (also one at Swanton Novers on 15th August).  2020 wasn't a great deal better with 9 at the meadows between 9th May and 20th June and singles on 11th and 16th September.  More in Cornwall in early October including 20 at Higher Bosistow.

Apple-leaf Skeletonizer Choreutis pariana - None.  I am yet to see this species but it's fairly widespread and not all that rare, so I'd have thought I would have a reasonable chance of finding one  locally someday.  I am also yet to come across any of the rarer Prochoreutis Metal-marks.

Lolly Moor reveals its secrets

On Tuesday Dave had visited the NWT reserve, Lolly Moor, and discovered what he thought looked like Cinereous Pearl Anania fuscalis.  Not one, but at least two and probably several more.  What's the deal?  Well, there was one Anania fuscalis recorded in the Attleborough square in 1996 but apart from that there have been no records in Norfolk since the 1800s.  Surely Dave had made a mistake...

I looked at his photos and thought they did indeed resemble Anania fuscalis so on Wednesday evening I headed down there with him to have a look.  It's a tiny wet meadow south of Dereham and surrounded by big hedgerows or woodland.  The first thing I noticed was Yellow Rattle growing there - the favoured foodplant of Anania fuscalis - a promising start!  The second thing I noticed was that the whole reserve was crawling with small pale moths which quickly proved to be Grass Rivulets (Dave had photographed these the day before too).  I've only ever seen Grass Rivulets at one site before, and I could count all of them over two visits on one hand.  Here I reckon we saw a bare minimum of 100 Grass Rivulets.  Among them we quickly picked out at least 3 Cinereous Pearls Anania fuscalis.  With a good view of their underwings there was no real doubt about the ID but I dissected one moribund individual just to make triply sure.  Dave had done good!

We weren't there for long but in the time we were we recorded a good variety of other species too: Yellow-barred Long-horn Nemophora degeerella (I'd had 3 of these in my lunch break too, at Barrow Common), Cork Moth Nemapogon cloacella, Large Lance-wing Epermenia falciformis (a species I've only ever seen twice before), Buff Rush Case-bearer Coleophora caespititiella, Water-mint Conch Phalonidia manniana, Hook-marked Straw Moth Agapeta hamana, 3 Common Marbles Celypha lacunana, Red Piercer Lathronympha strigana, 3 Meadow Greys Scoparia pyralella, Common Grey Scoparia ambigualis and 2 Straw Dots.

Among the plantlife were several Common Spotted Orchids and also Common Twayblade, a new species for me.
