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.

Lolly Moor and Marsham Heath

I thought a pleasant warm evening on 31st August might be good for dusking so I popped down to Lolly Moor NWT reserve.  It felt a bit slow but in the end it wasn't bad: White-speckled Clothes Moth Nemapogon koenigi (just realised this has changed its name from N. wolffiella), Diamond-back Moth Plutella xylostella, 18 Common Marbles Celypha lacunana, Rush Marble Bactra lancealana, Red Piercer Lathronympha strigana, Marsh Grey Eudonia pallida, Mother of Pearl Pleuroptya ruralis, Common Carpet, Green Carpet, 5 Straw Dots and Pinion-streaked Snout.

One spider that found itself in the net was duly photographed and subsequently identified as Linyphia triangularis, the first time I've identified this species.   Other non-lepidopteran interest included the brown lacewing Hemerobius humulinus and a Hobby.

Moths at home that night consisted of Horse Chestnut Leaf-miner Cameraria ohridella, Diamond-back Moth Plutella xylostella, Woundwort Case-bearer Coleophora lineolea, 2 Little Dwarfs Elachista canapennella, Brown House Moth Hofmannophila pseudospretella, Chequered Fruit-tree Tortrix Pandemis corylana, 2 Light Brown Apple Moths Epiphyas postvittana, 5 Garden Rose Tortrixes Acleris variegana, Barred Marble Celypha striana, 6 Common Marbles Celypha lacunana, Round-winged Drill Dichrorampha simpliciana, Common Grass-veneer Agriphila tristella, Elbow-stripe Grass-veneer Agriphila geniculea, 2 Narrow-winged Greys Eudonia angustea, 3 Garden Pebbles Evergestis forficalis, Pale Straw Pearl Udea lutealis, Common Plume Emmelina monodactyla, Orange Swift, Single-dotted Wave, 2 Common Carpets, 3 Common Marbled Carpets, 3 Green Carpets, Treble-bar, 15 Brimstone Moths, 2 Canary-shouldered Thorns, 4 Dusky Thorns, 6 Light Emeralds, 8 Flame Shoulders, 21 Large Yellow Underwings, 10 Lesser Yellow Underwings, Lesser Broad-bordered Yellow Underwing, Small Square-spot, 6 Setaceous Hebrew Characters, Square-spotted Clay, 8 Square-spot Rustics, Lychnis, Common Wainscot, 3 Centre-barred Sallows, 6 Flounced Rustics, Rosy Rustic, Frosted Orange, 2 Burnished Brasses, 12 Straw Dots, 9 Snouts and another Pinion-streaked Snout.

The following night Dave and I trapped at Marsham Heath.  We didn't manage to trap any of our targets but found several noteworthy moths nonetheless.  Perhaps the best was Brown Knot-horn Pyla fusca, a species I had only seen once before, at the same place in 2012.

Another 'second' was this Red Birch Slender Caloptilia betulicola.

Other species I don't see often included Birch Sober Anacampsis blattariella and 5 Dark Grass-veneers Crambus hamella.

We saw lots (at least 25) of Marbled Piercers Cydia splendana, but at least a lot of them looked bigger than usual and the majority were dark forms (none were the pale form that I usually see most often though some approached that).  Some were quite tatty but others were very fresh, yet the Cydia splendana I see at home peak in late July and are almost over by September.  It was almost as though these were a different species!  Confused, I retained a selection and checked them when I got home - they were indeed Cydia splendana.  Interestingly I see Cydia splendana feeds on Oak and Sweet Chestnut.  There are one or two oaks near my garden but no Sweet Chestnut nearby so far as I know.  Most of the other places I've trapped this species in the past have been near Oaks too.  Here at Marsham Heath there were lots of Sweet Chestnut (and some of these were caught flying around the Sweet Chestnuts).  Is it possible that Oak-feeding populations are paler and smaller and earlier on average than Sweet Chestnut feeding populations?  Pure speculation without more data, but something I shall be interested to study in future.  Maybe they're cryptic species...

Other things at Marsham Heath included Southern Hawker and the Brown Lacewing Hemerobius humulinus.  On the way home we saw a small (presumably young) Badger beside the B1145 just west of Reepham.
