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 - Lyonetiid Leaf-miners (Lyonetiidae), Ash-bud Moths (Praydidae) and Obscures (Autostichidae)

LYONETIA and LEUCOPTERA BENT-WINGS (LYONETIIDAE)


Apple Leaf-miner Lyonetia clerkella -12 in the garden between 15th June and 16th August 2019 making it my best year to date.  Also my first ever autumn generation example on 24th October, which was also my first of the dark melanic type.  Judging from photos published on the web it seems that dark types are normal for the second generation and rare in the first main generation.  On this one the vertex was white - on some examples even this is brown.  2020 was even better with 18 between 12th June and 16th August.  Also one netted at the meadows in 2020 and quite a few leaf-mines there in both years on Wild Cherry and also some on Blackthorn and possibly also on Hawthorn.

Striped Bent-wing Lyonetia prunifoliella - I found one on a Blackthorn leaf in a hedgerow at the Cathedral Meadows on 30th August 2019.  This was a new moth for me, and only the second Norfolk record and the first for the vice-county VC28.  This species became extinct in the UK in the 19th century and wasn't recorded for over 100 years, but very recently has re-colonised the south of the country.  It appears to be spreading northwards and mine was the first of 3 records in the county in 2019.  I imagine that within a few years it will be a common moth here, but time will tell.

Laburnum Leaf-miner Leucoptera laburnella - None.  This is a fairly common species that I saw at Bawdeswell but haven't yet found in North Elmham.


Boom Bent-wing Leucoptera spartifoliella - My first ever adult of this species was swept from Broom at the meadows on 13th July 2019.  A possible mine in the same Broom in 2020 but I wasn't certain about the ID.

Pear-leaf Blister Moth Leucoptera malifoliella - Leafmines found at the meadows on 30th August and 11th September 2019 but it wasn't until 2020 that I saw my first ever adult, one netted at the meadows on 26th June.

ASH-BUD MOTHS (PRAYDIDAE)


Ash-bud Moth Prays fraxinella - One in the garden trap on 23rd July 2019, my 4th here (all since 2017).  None in 2020.

Dark Ash-bud Moth Prays ruficeps - One in the garden trap on 26th July 2019 and singles on 5 nights between 16th July and 15th September 2020.  Prior to the 5 in 2020 I'd had 1-2 here in each of the full years I'd lived here.

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


BINDWEED BENT-WING (BEDELLIIDAE)


Bindweed Bent-wing Bedellia somnulentella - None.  I've only had one of these here, in 2017.



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


HAWTHORN MOTH (SCYTHROPIIDAE)


Hawthorn Moth Scythropia crataegella - None.  I'm yet to record this species locally - I didn't even manage it at Bawdeswell where my house was almost enveloped by an enormous Hawthorn hedge that hadn't been cut for years.  None at the meadows either, where the hedges are full of Hawthorn and Blackthorn.  Presumably this species' requirements involve more than just its foodplants.



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


OBSCURES (AUTOSTICHIDAE)


Four-spotted Obsucre Oegoconia quadripuncta - Totals of 12 between 16th July and 6th August 2019 and 20 between 25th June and 11th August 2020.  The 20 in 2020 was my best year so far and they peaked with 6 on 1st August.  Although the breadth of the pale bands is a good indicator, this species and the next are not supposed to be possible to definitively identify without checking their genitalia.  I suspect that in reality it might be possible to reliably assign some individuals to species without dissection but there is certainly overlap and some I've dissected have turned out not to be the species I had suspected.  Out of the 32, 30 were males.  Worth bearing in mind that Oegoconia caradjai may occur in Norfolk although there haven't been any records yet - some individuals could very easily be overlooked among quadripuncta.

Scarce Obsucre Oegoconia deauratella - Single males on 10th and 17th July 2019 plus a probable on 29th July which escaped before I could check it.  This species is annual here, averaging 2-3 per year but 2020 was my best year so far with 6 between 18th June and 30th July.  All were males.
