Review of 2019 and 2020 - Moths: Noctuids (Noctuidae) part 2: Daggers, Small Yellow Underwing and Sharks

NOCTUIDS (NOCTUIDAE)


Reed Dagger Simyra albovenosa - None.  I've not recorded this species locally and I'm well away from the strongholds for this species so haven't really been expecting to.  However there have been a couple of records just down the road at Worthing so maybe there's a chance I will find it round here.


Alder Moth Acronicta alni - None.  I seem to be a bit unlucky with this species as I've only ever seen 2, and they weren't local.  It's common enough and is known to occur locally, so surely I'll find one locally some day.


Dark Dagger Acronicta tridens - None.  I've caught 2 here, in 2016 and 2017, but this seems to be very much scarcer than Grey Dagger.  I've gen detted some reasonable candidates for Dark Dagger that have turned out to be Grey.


Grey Dagger Acronicta psi - Having averaged 7 a year here over the previous 4 years it was a disappointment not to catch any in 2019.  2020 was a bit better with 4 between 1st and 12th August; also one at the meadows on 18th July.

Sycamore Acronicta aceris - One at Weybourne on 5th July 2019 and one at the meadows on 7th July.   None at home, and none anywhere in 2020.  I've only ever caught this species at home 3 times, all in 2015.

Miller Acronicta leporina - None.  I've caught these at home on 3 occasions (2015, 2016 and 2018).


Light Knot Grass Acronicta menyanthidis - One came straight in to the LED lights as soon as I put them on at Allt Mollach on Mull on 13th June 2019.  This was a lifer for me - the species that has an extremely restricted range within Norfolk (but is much commoner in Scotland).  Scottish specimens like this are of a paler subspecies than the ones that occur here in Norfolk.

Knot Grass Acronicta rumicis - One in the garden trap on 20th July 2019 and 5 here between 21st July and 13th August 2020.  I've recorded this species here each year since moving in but I'd not had more than 4 in a year before.  Elsewhere one at the meadows on 22nd August 2019 and 18th July and 7th August 2020.

Poplar Grey Subacronicta megacephala - One in the garden trap on 2nd May 2019 was my earliest ever record.  That was the only one I caught at home that year and in 2020 I had 2, on 28th May and 14th June.  I had 16 in 2016 but that was exceptional - I've had 0-2 in every other year.  Elsewhere 4 at the meadows between 17th May and 18th July and one at Bintree Wood.  Although some examples are obvious I don't always find the identification of this species as easy as some recorders seem to - some examples of both Poplar Grey and Sycamore show reasonably prominent pale dorsal spots at the end of the cross-line such that there is overlap with Knot Grass in this character, and other characters seem to be quite variable and/or unclear.  With a few individuals I resort to dissection to satisfy myself the ID is correct, and although they now usually end up being what I thought they were, this wasn't always the case when I started doing this.

Coronet Craniophora ligustri - None in 2019 but 4 caught in the garden between 6th and 15th August 2020.  Annual totals vary from 0-5 here.

Small Yellow Underwing Panemeria tenebrata - A total of 8 at the meadows between 15th and 25th May 2019 (on 4 dates).  This was the second consecutive year they were found here in reasonable numbers (2018 was the first year the site was surveyed) but none were found in 2020.  Most were, as you would expect for a day-flying species, seen during the day but one was found by torchlight roosting on a leaf of the Apple tree.

Shark Cucullia umbratica - None.  I've not yet found this species locally but it has been recorded in my road before so it's surely only a matter of time.


Chamomile Shark Cucullia chamomillae - None.  This must be one of the most common and widespread moths that I've never seen.  Hopefully I'll catch one someday and there's no reason why it shouldn't be local.


Mullein Cucullia verbasci - One caught in the garden on 23rd April 2020, my fifth here (the others all in 2016-17).  Otherwise only larvae seen, but these were easy to find on the Mullein plants along the railway at the meadows - up to 20 between 21st May and 21st June 2019 and up to 18 between 15th May and 26th June 2020 (when there was also 2-3 on a solitary plant at the chapel).  Covid may have helped this species in 2020 as the railway company usually spray the railway every year, completely destroying the Mullein before it flowers and while many of the caterpillars are still feeding.  Presumably the caterpillars are destroyed along with plants.  There was no spraying in 2020 though the company are apparently wanting to spray much earlier in 2021.

Boughton Fen

On Saturday 2nd July I went to Titchwell to see, after several unsuccessful attempts, the Great Knot (see my birding diary).  The visit also got me a new hoverfly, Leucozona laternaria.  Other insects included a Painted Lady, Black-tailed Skimmer and a Yellow-tail caterpillar.

Leucozona laternaria, Titchwell, 2nd July

In the evening I joined others at Boughton Fen for another Norfolk Moth Survey event.  Probably the best moth was my first Comfrey Ermel Ethmia quadrillella, though a white Coleophora also proved to be one I'd not seen before: Pistol Case-bearer Coleophora anatipennella.

Other moths I don't see very often included 2 Ash Bud Moths Prays fraxinella, Hawthorn Moth Scythropia crataegella, 3 Twin-spot Carpets and Striped Wainscot.

A few other inverts were identified.  Stuart confirmed the Mayfly Procloeon bifidum and a Strawberry Snail.  I can't work out what this slug is though, possibly a juvenile Black Slug agg.?

Another one I can't ID for sure is this nymph, but I think I'm in the right ballpark with Muellerianella fairmairei.

Caddisflies included Limnephilus auricula, Limnephilus marmoratus plus this one that I've rarely seen: Trichostegia minor.

Last but not least, and another one where I can't take any credit for the ID, was this male Glow-worm (it's only the females that glow).
