Review of 2019 and 2020 - Moths: Poplar and Pine Cosmets (Batrachedridae) and Case-bearers (Coleophoridae) (Part 1)

POPLAR & PINE COSMETS (BATRACHEDRIDAE)


Poplar Cosmet Batrachedra praeangusta - 2 in my garden trap on 23rd July 2019 and one on 29th July 2020.  Also one at Swanton Great Wood on 27th August 2019.  I had never seen this species until 2018 when I recorded 3 at home and one elsewhere - is this species suddenly increasing, or has it just enjoyed a couple of good years, or is it just coincidence?

Poplar Cosmet Batrachedra praeangusta, North Elmham, 29th July 2020

Pine Cosmet Batrachedra pinicolella - One in the garden on 24th June 2020.  This species has seen a massive upsurge in records in recent years starting with one at my old house in 2013, the first county record for 129 years!  I caught them here in North Elmham in 2015, 2016 and 3 times in 2017 but although records across the county continued to increase I then had a couple of blank years in 2018-19.

CASE-BEARERS (COLEOPHORIDAE)

4 new species for the garden in 2019 (including one that was completely new for me) and another completely new one in 2020 brought my garden Coleophora list up to 43.


Silver-streaked Case-bearer Coleophora limoniella - None in 2019 but 20 swept from a single Sea Lavendar plant at Brancaster on 2nd July 2020.  One at home in 2018 was quite unexpected given that this saltmarsh species hadn't turned up inland in Norfolk prior to that year.  I don't expect a repeat anytime soon.


Common Oak Case-bearer Coleophora lutipennella - 3 in my garden trap between 10th and 22nd July 2019, a slightly below average year for this species, and then 4 between 29th June and 6th August 2020.  Also 3 at the meadows (26th July 2019 and 18th July and 7th August 2020) and one at Bintree Wood.  These are always dissected to confirm ID - I'm yet to find any features that are even indicative of this species rather than the similarly common flavipennella.

female Common Oak Case-bearer Coleophora lutipennella, North Elmham, 6th August 2020

Rose Case-bearer Coleophora gryphipennella - None.  I've only had one of these here (and anywhere) so far, in 2018.


Tipped Oak Case-bearer Coleophora flavipennella - One at the meadows on 7th July 2019 followed by 5 in the garden trap between 8th and 22nd July and then another 5 in 2020, between 16th June and 7th July.  Fairly typical years for this species which seems to be a little bit commoner than lutipennella (from which separation requires gen detting).

Buff Birch Case-bearer Coleophora milvipennis - None.  I've had just one record of this species here, in 2016.  It's tricky species to identify even with reference to the genitalia - my 2016 record required input from an international expert to confirm.


Pale Elm Case-bearer Coleophora badiipennella - None.  I've only had one of these here too, in 2015.


Dark Elm Case-bearer Coleophora limosipennella - None.  One of the more widespread and well-recorded Coleophora that I've not yet recorded.


Blackthorn Case-bearer Coleophora coracipennella - A female caught here on 23rd July 2019, my second record following one in 2017.  None in 2020.  Described as rare, although there have been a few recent records so I suspect it's more a case of being under-recorded.

female Blackthorn Case-bearer Coleophora coracipennella, North Elmham, 23rd July 2019

Common Case-bearer Coleophora serratella - Adults trapped at home on 23rd July 2019 and 26th and 31st July 2020.  Cases found at the meadows on Downy Birch on 26th April 2019 and Rough Chervil on 3rd June 2020, the latter causing me an ID challenge as Rough Chervil doesn't have any Coleophora listed as occurring on it, but thanks to Keith and Rob who pointed out that some Coleophora (especially this one) wander from their foodplants in order to pupate.  Although this is supposed to be the commonest of all the Coleophora I didn't find my first until 2018 (when I caught 4, including 3 here).

Apple & Plum Case-bearer Coleophora spinella - 4 trapped at home between 12th and 23rd July 2019 and 3 between 3rd and 17th July 2020.  4 is the most I've had here in a year - 2 is more typical.  Also a case that I think was probably this species on Hawthorn at the meadows on 15th May 2019.

male Apple & Plum Case-bearer Coleophora spinella, North Elmham Cathedral Meadows, 13th July 2020

Scarce Thorn Case-bearer Coleophora trigeminella - None.  I had 2 here on one night in 2017, the year I recorded Norfolk's second, third, fourth and fifth records of this species.  There have been others since so a repeat wouldn't be altogether unexpected.


Osier Case-bearer Coleophora lusciniaepennella - One caught at home on 23rd June 2019 and one at Weybourne on 5th July.  None in 2020.  I've had 3 previous records here (2015 and 2017).

female Osier Case-bearer Coleophora lusciniaepennella, Weybourne, 5th July 2019

Violet Case-bearer Coleophora violacea - None.  Although there aren't large numbers of records of this species it must be fairly high up on the list of next most likely candidates to be added to my Coleophora list.


Shaded Case-bearer Coleophora potentillae - None.  Another one that I haven't seen yet but must have a good chance of cropping up here.  So far the nearest I've got is seeing its feeding signs.

A first for Norfolk - nearly!

On Monday 19th June I considered having a wander round Beetley Common, just 5 minutes away and good for insects last time I was there.  But there had been a Lesser Emperor at Selbrigg Pond for a few days and it was reported as still being there, and I've never seen a Lesser Emperor in the UK, so I thought I'd head there instead.  That proved to be a very unfortunate decision!  There were a few dragonflies on view including normal Emperors and Red-eyed Damselflies, but I couldn't find the Lesser Emperor.  A couple sitting by the pond said there had been people there watching it who left just before I arrived, and I someone who must have arrived just after I left tweeted that it was still there shortly afterwards, so it seems that I was very unlucky.  To make matters worse Kevin du Rose visited Beetley Common while I was at Selbrigg and found, guess what - a Lesser Emperor!

The lady sitting by the pond found this caterpillar which she wanted me to identify.  I'm rubbish at caterpillars and couldn't help, but having now looked it up I think it's an Oak Beauty.

I made up for the disappointment with Lesser Emperor when it came to checking the moths I caught overnight.  Among them was a smart streaky grey gelechiid which looked interesting.  It looked like an Anarsia species, but not Anarsia spartiella, the one I've seen before - it was too streaky.  It looked more like Peach Twig Borer Anarsia lineatella, a species only recorded in Norfolk once before and usually found among imported peaches.  Well this wasn't among imported peaches and I wasn't convinced it was this species, but on first look I couldn't find any similar species - certainly not on the Norfolk Moths website anyway, nor the UK Moths website.  My next stop was Lepiforum where I discovered a species called Anarsia innoxiella, very similar to Peach Twig Borer.  Helpfully Lepiforum has an image detailing the differences between the two species and sure enough my moth was spot on for Anarsia innoxiella!  I then checked back on Norfolk Moths, UK Moths and some other British moth websites and couldn't find innoxiella mentioned anywhere... surely I hadn't found a first for Britain?  Next stop was Google and that led me to the Gelechiid Recording Scheme and there on its news page was the information that Anarsia innoxiella had been split from Peach Twig Borer only as recently as March 2017.  It stated that, "Initial examination of recently light-trapped British material, which were thought to be A. lineatella, suggest many could well be referable to the new species, Anarsia innoxiella."  Hmm, "could well be"?  Does that mean innoxiella hasn't actually been confirmed yet?  Are they waiting for a specimen?  Could mine be the first confirmed British record?  Well no, for elsewhere on the same website I found a page for the species which clarified that there have indeed been confirmed records and that "Early indications are that it is well established in south-east England but should be considered at best local in its distribution."  So certainly not new to the UK but maybe to Norfolk?  None on the Norfolk Moths website so it was looking hopeful that I might at least have found a first for Norfolk.  Well sadly it turns out that it wasn't even that - not quite - for Andy Wallis had trapped one just three nights earlier.  I'd been pipped to the post - and not for the first time (a very similar thing happened with my first Italian Tubic Metalampra italica).  Still, a very nice find, second for Norfolk, first for VC28 and of course a new moth for me.

Among the rest of the catch several species were new for the year including two I have rarely seen before (both on just single occasions here before) - Thistle Ermine Myelois circumvoluta and Haworth's Pug.

Viburnum Button Acleris schalleriana was my third record and first outside of January/February.

Satyr Pug was also my third, and for the third time its identity wasn't realised until after it had died.  Here it is with the Haworth's Pug and a Grey Pug also caught that night - I suppose I shouldn't beat myself up too much for not realising I had all three species straight away...

Monopis obviella

After an excellent night's mothing at Warham Greens I returned home to check my garden moth trap - and it was busy!  Actually 244 moths of 98 species isn't remarkable for the second half of June but it was one of the best nights of the year so far and there were lots new for the year.  The highlight was a belated lifer, Yellow-backed Clothes Moth Monopis obviella.  I've had a few of the similar but rarer Pale-backed Clothes Moth Monopis crocicapitella before but obviella has eluded me until now.  When I did get a good candidate for one last year it managed to escape before I could confirm it, so nice to get one sorted at last.

New for the house was Meadow Neb Metzneria metzneriella and it was interesting to compare it to a Burdock Neb Metzneria lappella (new for the year) - very similar but the rufousy tones along the costa on metzneriella were distinctive if subtle.

A Larch-bud Moth Spilonota laricana was only my second and new for the house.

Mayflies included a male Pond Olive Cloeon dipterum, subimago when caught but emerging into imago state by the time I came to identify it.

There were four beetles in the trap, three of which were new for the house (no doubt because I'm trying much harder than before): the water beetle Rhantus suturalis, Lesser Stag Beetle Dorcus parallelipipedus and completely new for me, Mealworm Beetle Tenebrio molitor (the fourth was Cantharis cryptica).
