Marlow Bottom November to date

 I have only put the trap out on a few days this month, but have managed 26 species on the days I tried. 

There have been a few migrants, though nothing exciting: 

Udea ferrugalis (1st and 17th)
Plutella xylostella (2 7th, 1 17th)
Silver Y (17th).
Two Whitepoints (17th) were pretty worn and can be late, so presumably local moths.




Three Cypress Carpets (17th) were my first multiple occurrence, but becoming more regular here.


Other species seen:

Tachystola acroxantha (17th) - presumed, but worn
Blastobasis lacticolella (1st)
Androsis sarcitrella (1st)
Acleris sparsana - 11
Cydalima perspectalis (1st) first November record here - still alive in the trap on the 8th, when released properly!
Oak Hook-tip (1st)
December moth - 5
Red-green Carpet - 15
Common Marbled Carpet - 3
Winter moth - 1
November moth sp - 16
Feathered Thorn - 18
Scarce Umber (17th)
Mottled Umber - 7
Light Emerald (1st)
Sprawler - 5
Pink-barred Sallow (8th)
Yellow-line Quaker - 18
Brick - 6
Brindled Green (1st)

Presumed Tachystola acroxantha

There is one worn Acleris sp from the 17th that I haven't been able to identify - does anyone have any opinions?

  1. Hi Adam, wouldn't your Acleris sp. be one of the less common forms of A. sparsana? It looks to have at least some of the expected markings and one form has 'whitish-grey ground colour'.

  2. Hi Adam,

    Tachystola acroxantha is correct. I'm not sure about the Acleris but it could indeed just be another rather tired-looking sparsana. Good to see you getting increasing numbers of Cypress Carpet - perhaps that means it'll now start wandering northwards!
