Not-so-Scarce Umbers

A quick wander along the railway at the bottom of the meadows after dark on 8th November turned up a few interesting things.  There wasn't much flying but the eye-shine drew my attendtion to this Satellite.

The only other moth I found was a London Dowd Blastobasis lacticolella resting in some Gorse.  The Broom wasn't as productive as it can be, but there was a Broom Psyllid Arytaina genistae. As is often the case, the Oak trunks produced a better variety including the springtail Orchesella cincta, Great Four-spot Treerunner Dromius quadrimaculatus (a beetle), Harlequin Ladybird Harmonia axyridis and White-legged Snake Millipede Tachypodoiulus niger.

I also found a bug which at the time I identified as my first Anthocoris confusus.  However I subsequently recorded more Anthocoris along here and when I was figuring out the next one that I realised I was mis-reading the description of one of the features, and it turned out to be nemoralis.  Now there's no reason to assume I made the same mistake when examining the confusus, but as none of the subsequent examples so far have been confusus I'm left feeling less than 100% sure that I didn't make a mistake.  So I am deleting this record until such time as I find another.

There was one lifer for which I'm still ok with the ID though, not that it's a group that I have much experience with - a Variegated Oak Aphild Lachnus roboris.

The moths in the garden trap that night were 3 Narrow-winged Greys Eudonia angustea, White-point, 2 Sprawlers, 2 Green-brindled Crescents, 2 Chestnuts and Yellow-line Quaker.

The following night there was Garden Rose Tortrix Acleris variegana, 2 Pale November Moths, a female November Moth agg., 2 Feathered Thorns, 2 Mottled Umbers, Sprawler, Chestnut, 3 Yellow-line Quakers and the caddisflies 4 Limnephilus lunatus and Limnephilus flavicornis.

Just 4 Feathered Thorns and a Setaceous Hebrew Character the following night.  Next day there was a Common Mompha Mompha epilobiella in my hall, and in the trap Diamond-back Plutella xylostella, Rusty Oak Button Acleris ferrugana, Sprawler, Chestnut and 2 Yellow-line Quakers.

The Mottled Umber shown above was, I would say, at the Scarce Umber end of the scale - the sort that could reasonably be confused with Scarce Umber.  In fact I checked the genitalia just to make sure.  Three nights later there were some real Scarce Umbers - 3 no less.  I've never caught 3 in one night before and with a blank year in 2017 these were my first since 2016.

Other things that night were 2 Light Brown Apple-moths Epiphyas postvittana, December Moth, November Moth, Pale November Moth and Satellite.

The following night there was November Moth, Yellow-line Quaker, the caddisfly Limnephilus lunatus and a Common Wasp.

The 14th was another quiet night for moths with just 2 December Moths, 3 Feathered Thorns and Setaceous Hebrew Character. There were also 2 caddisflies Limnephilus lunatus and, for the first time in a while, a fresh emergence of leafhoppers.  All were similar yellow leafhoppers which normally prove to be either one of the two Fagocyba species (usually cruenta) or one of the several Edwardsiana species.  A couple of these had cloudier apexes of their wings compared to the others so I wondered if two species might be involved, but in fact although two species were involved, the variation in the cloudiness of the wing tips was all within a single species.  They consisted of 1 Fagacyba carri and 6 Fagocyba cruenta.

Next day there were 2 Light Brown Apple-moths Epiphyas postvittana, Ashy Button Acleris sparsana, 3 December Moths, probable November Moth, Mottled Umber, White-point, Sprawler, the caddisfly Limnephilus lunatus, Black Sexton Beetle Nicrophorus humator and 2 more Fagocyba cruenta.

On 16th I had another after-dark look round the meadows with the head-torch.  This leafmine appears to belong to Common Oak Pigmy Stigmella roborella.  The larva was in there but motionless and I'm not convinced it was alive.

The only adult moth I could find was a Winter Moth, my fisrt of the winter.

There were also 3 of the barkflies Ectopsocus briggsi, the beetle Great Four-spot Treerunner Dromius quadrimaculatus, 3 7-spot Ladybirds Coccinella septempunctata, and a Common Rough Woodlouse Porcellio scaber.

Two different Oak trunks had these odd ant-like insects on.  It was clear enough that they weren't actually ants but apart from assuming they were some kind of hymenoptera I couldn't figure out what they were.  I tweeted some photos and received a response from Simon Knott who confirmed they were gall wasps of the family Cynipidae, likely to be Biorhiza pallida agamic female.  Looking into that and comparing with the specimens it looks bang-on, so my first Oak Apple Gall Wasps Biorhiza pallida.

A particularly fine set of fungi was this Sulphur Knight.  I had a pretty good idea about what these were already but James Emerson has been brilliant helping me with fungus IDs lately - always very much appreciated.  These looked a little more lemony-yellow in life (albeit only in torchlight) than they do in the photos.

A new beetle, ichneumon and sawfly but little moth excitement

I haven't done any updates for a few days, largely because there hasn't been much to say - until last night.  More of that later, but here's a catch-up first of what's turned up in the trap since last Monday.  The highlights were 2 Ruddy Flat-bodies Agonopterix subpropinquella (23rd and 26th), my third and fourth ever and new for the year and a Lead-coloured Drab (27th).

Yesterday at Burnham Overy I saw my first Buff-tailed Bumblebee of the year.

In the evening I didn't have time to go far and set up moth-trapping properly (except in the garden of course) which is a shame as it was a good night.  I did have just enough time to wander round a couple of local sites with Dave looking for moths in torchlight.  It was pretty unsuccessful really - Shoulder Stripe at Creaking Gate Lake and March Tubic Diurnea fagella at Honeypot Wood, plus a few moths that we failed to catch and identify.  Lacewings were in evidence, all those that were identified being Chrysoperla carnea.

The one thing that made the effort worthwhile was a new beetle species for me, Dromius quadrimaculatus.

After that inauspicious start to the evening I was very pleased with the contents of my moth trap this morning... but I'll save that for another post.

Dave brought me a couple of moths that Andrew Duff had collected from Woodbastwick on 27th March.  One which he thought I'd be particularly interested in was an Agonopterix sp.  Its pattern resembled Agonopterix heracliana but could also be ciliella but the overall colour was extraordinary - strong pinkish tones especially along the sides of the forewings.  Agonopterix heracliana can show a few pink scales but I have never seen anything remotely close to this before. Anyway, I did the business and it proved to be a female Common Flat-body Agonopterix heracliana.  So not an unusual species but definitely an unusual appearance.
