Mompha bradleyi?


 Am I safe in ID'ing this as Mompha bradleyi, without dissection? The Field Guide seems to suggest it would need genitalia examined to separate from divisella, but the "hourglass" is distinctly buff-tinged, rather than pure white, so I can't see it being the latter. I have had bradleyi here before (gen det), plus divsella looks very unlikely per the the atlas.

Too worn to ID?

 Hi there,

This rather unexpectedly turned up last night. Can those more experienced that me make anything of it?

Many thanks,

David

Mine on Comfrey

 I found this leaf-edge roll on Comfrey yesterday. It looks almost identical to that of Parornix devoniella, but the nearest hazel is ~5m away, and as far as I can tell, (the top leaves are not accessible), there are none of the blotch mines of that species on it. There appears to be nothing that mines Comfrey that creates such a roll, so a bit of a puzzle! The roll is 3cm long, and empty apart from frass at one end, (the left hand end in the image below.)

New arrivals for the 2024 garden list have tailed off significantly now and there are very few species left which are guaranteed to put in an appearance this year, Sprawler, Scarce Umber and December Moth (as well as Winter Moth which was seen back in January) being the only ones that spring to mind.  Added over the past two weeks have been:  

     (1st)  Merveille du Jour
     (3rd)  Brick
     (4th)  Acleris sparsana
     (5th)  Figure of Eight, Yellow-line Quaker
     (7th)  Musotima nitidalis, Feathered Thorn, Scarce Bordered Straw
     (9th)  November Moth
     (15th)  Pale November Moth

November Moth (genitalia checked), Westcott 9th October

Figure of Eight, Westcott 5th October

Merveille du Jour, Westcott 1st October

There have also been a few "seasonal firsts" recently of moth species already recorded post-hibernation much earlier in the year but which have appeared again now as freshly-emerged specimens.  They include Satellite (3rd October), Chestnut (5th), Dark Chestnut (6th), Grey Shoulder-knot (12th) & Cypress Carpet (14th), while Red-green Carpet has been seen regularly in the traps since 22nd September.  The first Mottled Umber of the winter appeared last night (15th).

One or two late individuals of summer species have visited the traps, the most unexpected of which was Chocolate-tip (1st October).  This was very unusual and may be an attempt at a third brood because the last example I saw was way back on 19th July.  Yellow-tail (6th), Dark Arches (14th) & Copper Underwing (15th) were somewhat less remarkable, but sightings of Neocochylis molliculana (7th & 9th) were my latest ever records for that species.

The only obvious migrants of late have comprised Plutella xylostella (2nd, 6th, 15th), Udea ferrugalis (2nd, 15th), Scarce Bordered Straw (7th) and Palpita vitrealis (14th), but Delicate has appeared almost nightly in the garden throughout this period (17 individuals) and I suspect many of them will be migrants because there has been quite an influx at coastal sites.  However, as has already happened with White-point, Delicate is a species which I believe may also be in the process of becoming established in our area.  There was another sighting here of Plumed Fan-foot (8th), this time during the day when it was disturbed from vegetation, and it may or may not have been a migrant.

Palpita vitrealis, Westcott 14th October

Lunar Underwing appears to be on the way out here now and to date I've managed 749 individuals since the first one on 15th September.  That might seem quite respectable but it is actually not a particularly good total for the garden because in eleven of the past 20 years the moth has achieved counts of more than 1,000 of which three have been over 2,000.  An oddity on 4th October was a noticeably tiny (but fully formed) example of Pink-barred Sallow which came to light here, having a forewing length of just 10mm.  It is shown below next to a normal sized specimen.   

Pink-barred Sallows, Westcott 4th October

A bit more casual searching for leaf-mines in the garden over the last couple of days has produced a number of new species for 2024, including vacated examples of Stigmella luteella (on birch) & Stigmella regiella (on hawthorn) as well as active mines of Stigmella microtheriella (on hornbeam), Ectoedemia intimella (on sallow), Ectoedemia occultella (on birch) and Tischeria ekebladella (on our very young oak).  I was particularly pleased to find Ectoedemia intimella, the mine being on a fallen leaf of narrow-leaved sallow Salix cinerea.  The species has only been recorded here once before, ten years ago, and again it was an active mine on a fallen leaf but on that occasion of Crack Willow Salix fragilis.  That particular tree is unfortunately no longer with us because it started to collapse in high winds three or four years ago so I thought I'd lost all its associated leaf-miners.

With apologies...a few more mines for ID

 

After ploughing through both volumes of Micro-moth Field Tips, I am still struggling to identify these mines found this afternoon, so some help would be appreciated. (It feels a bit like when I started trying to identify micros!).

The first two examples are on birch, on the underside of the leaf, and both have active larvae in them, but I can only just see the head moving, so no detail.






The next two are on hazel and appear to be vacated--images of both upper and lower surfaces. Both have a mine in the body of the leaf, plus an edge folded over. My guess for these is Parornix devoniella.





The final mine is on beech, and here my guess is Stigmella tityrella


Thanks

Evidence of Choreutis pariana?

Is this evidence of Choreutis pariana? The leaf is from an apple tree, and the mined area is translucent. The leaf edge is curled over as shown in the second image. There are very few images of the mine online, but those I have found do not appear to be on the edge of the leaf like this. As it's not a species I have seen here, and it doesn't seem that common in the region, I strongly suspect it is not!

Thanks

Whizz Pop Bang!

I don't know how many of our blog's households subscribe to Whizz Pop Bang!, which calls itself the Awesome Science Magazine for Kids, but it's encouraging to see that its Emmi's Eco Club column features a DIY children's moth trap. I warned the parent who tipped me off that it isn't the best time of the year to start light-trapping but apparently they've run it as part of a Hallowe'en, world of darkness theme. Anyway, it can always be set aside until the Spring.  Or maybe they'll get a Porter's Rustic. Martin Wainwright, Thrupp, Oxon

Another Snowberry mine

 Checking the Snowberry in my garden again today, I found the mine pictured below which this time I think looks good for Phyllonorycter trifasciella. The leaf is strongly distorted and there are creases on the underside of the mine, both features mentioned in Micro-moth Field Tips. 




I am reluctant to open the mine in case pupation has not yet occurred, but I suspect that, if it is this species, then if I retain it, it may well emarge in a month or so?

Thanks

Caloptilia honoratella iRecord frustration!

 I attempted--and failed--to upload a batch of records to iRecord from a .csv file today. For some reason it would not recgnise Caloptilia honoratella, and the species was not in the dropdown list. Yet there are records in iRecord of Caloptilia honoratella, so it's a mystery why it wouldn't acccept it. 

As there is no option to drop a species at this stage in the upload process, rather than start all over again and remove it from the spreadsheet, I decided to change it to a random Caloptilia species that was on the list and delete it later. However I never got the opportunity to do so as the server failed to respond in time, so nothing got uploaded. What a waste of time!


 


Ypsolopha sequella check

 Just checking that this is Ypsolopha sequella rather than vittella.



Also from last night a nicely coloured Carcina quercana

Mines of Royal Leaf-miner (Phyllonorycter pastorella) in Bucks

I recently found a mine of the Royal Leaf-miner Phyllonorycter pastorella near Peterborough.  I noticed the scarcity of records across the Upper Thames area (albeit only records up to 2022) and thought I would have a look for it locally.

Phyllonorycter pastorella mines long-leaved willows such as Hybrid Crack-Willow Salix x fragilis, Crack-Willow Salix fragilis, Weeping Willow Salix x sepulcralis and White Willow Salix alba.  

I had a short walk around Hughenden Park this morning, and found several mines on three different looking willows.

Phyllonorycter pastorella on Weeping Willow Salix x sepulchralis.

Phyllonorycter pastorella on Hybrid Crack Willow Salix x fragilis

Phyllonorycter pastorella on Crack-Willow type Salix fragilis agg.

The first record of this species was from Buckingham Palace gardens in 2014.  It seems to be spreading quickly with records of mines from Kent west to Oxfordshire and north to Nottinghamshire. 

If you have long-leaved willows nearby (they usually occur near water) it is worth checking them out.   It is a lower surface mine extending from the centre vein to the leaf edge and with a single strong crease.  Pupation in the mine in a flimsy cocoon and frass in the opposite corner.
