Newbie tiggerish enthusiasm

 The first year of identifying moths must be one of the most exciting things to do without leaving home!

I'm sure the excitement wears off as the years cycle round and there isn't so much new, but at the moment there are new species on most nights. Some are striking in appearance, others are more mundane but still intricate in their pattern detail and some just exquisite without being spectacular - I'm thinking in particular of the Feathered Gothic that appeared a cople of nights ago, followed by the Frosted Orange and Black Rustic (much as Dave W's list). The only disappointment is that such beautiful species are all designated as common - which they might be in numbers and distribution - but not in their appearance.

Survivor

 

This little chap fell on to the windscreen in Wolvercote's Port Meadow car park, initially un-noticed, and then survived the 50mph stretch along Frieze Way and a visit to Kidlington Tesco's before ending up snugly in the wipers, above. I think it's a young Lime Hawk cattie but would be glad to know if I am wrong.  Thanks as always. Martin Wainwright, Thrupp, Oxon

Gap filling

The last two nights have seen me trapping at two private sites within SP82 (the least well recorded 10km square in Bucks), both of which I've been visiting monthly since April in order to try and give the area's species list a boost.  One site is near Soulbury and the other near Stewkley.  Last night's visit to the latter location was particularly good with close to 80 species seen, more than acceptable in late-August for what is basically hedgerow habitat (certainly a better result over three hours than what was achieved all night in my garden!).  There was nothing particularly noteworthy but some of the counts were good, the highest being Small Square-spot (90), Green Carpet (63), Square-spot Rustic (57), Common Wainscot (56) & Large Yellow Underwing (51).  It was interesting to see autumnal species appearing, with Feathered Gothic (4) and Brindled Green (2) recorded in addition to Centre-barred Sallow (14) which has been out for a week or two now.  The Brindled Greens were my first ever August sightings of that species.

A rather smart addition...

Clouded Magpie Stowe 28 August 2024

The Atlas seems to indicate that there have been no records of Clouded Magpie in Bucks north of  Aylesbury for over 50 years!.
I do have some small Wych Elms in the garden, so possibly locally bred? It certainly looks fairly fresh. 

Hello Again

Look who's come back to Thrupp after a year away - classically under the second-last eggbox in a trap otherwise rather thinly-populated by Brimstones, Light Emeralds, Green Carpets and especially Snouts.  This is much my earliest, I think, but I will check my records which saw the first Nonpareil on 16 September 2019. The following year I had ten!  Martin Wainwright, Thrupp, Oxon

Update: my previous records are: 3 Sept 2020 (2), 4 Sept 2020, 5 Sept 2020, 10 Sept 2020, 15 Sept 2020 (2), 18 Sept 2020, 21 Sept 2020, 2 Oct 2020, 21 Sept 2021(3) and 5 Sept 2022.  I always remember that in that first run of dates in Sept 2020, Marc Botham had six in one night. M

Treble bar?

 Query on what i think is a female treble bar,can you confirm for me please,179 of 29 species last night including a nice fresh gold spot,my best total for this year but over half were large yellow underwings,

Wood Carpet?

 This is the second night running I've had what I think is a Wood Carpet. No grey line on the white cross band and more pronounced projection on dark cross band. Cholsey. SU56941 Or is it a Common?

Thanks

Fat-hen leaf-miner - Chrysoesthia sexguttella (Gelechidae)

A leafmine to look for at the moment is Chrysoesthia sexguttella (Gelechidae).  This is a rarely recorded species, I was astonished to find that it was a county first (for VC24) when I found it in 2013.  I suspect that it is simply very under-recorded

It mines the leaves of Goosefoots Atriplex sp. and Oraches Chenopodium sp.  

I found it again last week on my allotment in the leaves of Fat-hen Chenopodium album.  

Note that the Beds moth site says that a tenanted mine is required for acceptance (in Beds), because of possible confusion with fly mines.  Because my mine was vacated, but did not look like a fly mine, I checked with Andy Banthorpe and he confirmed this was C. sexguttella.

Fat-hen can be a common plant, particularly on waste ground and manure heaps, worth checking it if you find any.   Look out also for mines of Chrysoesthia drurella which also mines Fat-hen.

Possible Coleophora follicularis?

I know it can only be reliably identified by dissection, but is this plausible as Coleophora follicularis? It was in my trap in west Oxon this morning (26th Aug). I do have Hemp Agrimony in my garden.

Oblique Carpet

I had what I think is an Oblique Carpet in my actinic trap in west Oxon this morning (26th August). This seems pretty uncommon in VC23.

Two thoughts and a possible Scythris

 In my Oxford garden on 23 August came these three that I was not sure of:

1. Dusky brocade? It was with a common rustic and had noticeably longer wings.

2. Zeiraphera isertana?

3. I wonder if this is Scythris limbella, a species I got on 9 August last year as the first for the area for a few years.

 

Worth checking

 

A couple of nice arrivals here on the very wet night and morning yesterday, I was going through the soggy eggboxes with my granddaughter who got a bit dispirited, so I had a second check some hours later, Finally I did a third audit in the late afternoon and only then found the Pinion-streaked Snout above, which has only visited me once before (or else I have overlooked or Straw Dotted it on other occasions).  It was also nice to have an Old Lady, a moth which I suspect may be renamed before too many years go by.

Eudemis profundana?

Does this tortrix look good for Eudemis profundana? It is not as well marked as other examples I have recorded.

Pheromone power!

 This year I tried for Gypsy Moth using a pheromone lure, and having successfully trapped one in the garden, and also used it to establish the species' presence locally in another two 1km squares, I returned the lure to the freezer, washed the basket, and put the empty trap back in the garage. I was therefore rather surprised when I found a Gypsy Moth in the trap (in the garage) a couple of days later! I decided that there must be traces of pheromone on the trap itself and washed that too. 

But just out of curiosity, I put the washed trap with empty washed basket out overnight last night...only to find a Gypsy Moth in it this morning! Clearly these pheromones are pretty persistent!

County first on Bucks Invertebrate Group meeting at Stowe NT

I led a Bucks Invertebrate Group meeting at Stowe Park and Gardens (National Trust) last Saturday.  We were fortunate to be joined by Andy and Melissa Banthorpe, VC30 moth recorders and very keen on leaf-miners.  

Late in the day, we came across a Cornelian Cherry Cornus mas and Andy & Melissa found (vacated) mines of Antispila treitschkiella, which is a county first for Bucks (VC24). 
(The name treitschkiella was formerly applied in error to what is now known to be Antispila petryi.)

Vacated mine of Antispila treitschkiella, Stowe NT, 17 August 2024

Despite this being the first Bucks record, it is probably easy to find, if you can locate the foodplant, Cornelian Cherry Cornus mas, which is widely planted in gardens and parks.  It is a Dogwood but it has red fruit, see photo below.  If you know of any plants, it would be a good time to check them for mines. 

Cornelian Cherry Cornus mas, Stowe NT, 17 August 2024

If you don't know of any, but want to find them, the best time is in spring when they flower.

Some other good finds: a larva of Triple-spotted Pug Eupithecia trisignaria was found by Melissa in the seedhead of Wild Angelica Angelica sylvestris, this may be the first county record of the larva of this local and uncommon species.

Sycamore Acronicta aceris larva, Stowe NT, 17 Aug 2024

Phyllocnistis unipunctella on Black Poplar Populus nigra sens. lat.

We recorded another 137 species on the day (and still counting!) of which 54 were moths (mostly leafmines).  

If you are interested in becoming a member of the Buckinghamshire Invertebrate Group and joining us on future field trips (it's free!) just go to our Contact us page.

Upcoming trips (with main focus):
31 Aug/1 Sept   College Lake (set moth traps and show to the public next day)
12 October        Bernwod Forest (leaf-mines and galls)

Choreutis nemorana in Denham

Following my own advice in my last post I looked for Figs trees along the local village road and almost immediately spotted the larval workings; stopped the car and sampled from the pavement! So second Bucks site after Wooburn Green last year (and this). No surprise at all! Keep looking!

Choreutis nemorana, new to VC22

 Larval workings (occupied) on an 8 year old fig in my sister-in-law's garden in Maidenhead Court. First record for VC22. Easily spotted, even at a distance! Get looking!

Plenty of Red

 

One moth which doesn't seem to be in short supply this year is the Red Underwing which has been making its presence felt here. A neighbour asked about the pair shown top left and then I opened our back door and the fine specimen shown at the top right fell down, dislodged, and was apparently stunned, something I've not come across before. As a result, it spread its underwings and obligingly allowed itself to be transferred happily to the gargoyle. Shortly afterwards another appeared and sat contentedly on the wall for over three hours in the afternoon sun. All were found by daylight. None in the trap yet.  Martin Wainwright, Thrupp, Oxon

The Gem in Denham

 A male on14th August to mv when catch numbers were still high, cf last night - 16th. First since two here in September 2019.

Apotomis and Dichrorampha queries

I think this first micro is Apotomis betuletana, but I wondered if it needed checking?

Also, I have this probable Dichrorampha species, but I imagine it needs dissection to confirm the species?
