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.

Beetley Common by torchlight and now caught up

I'd recently acquired a new headtorch with a very bright beam so on the relativly mild evening of 28th October I decided to have a wander round Beetley Common to see if it was any good for mothing.  In the first few yards 3 moths passed through the torchbeam, two of which I managed to net: White-triangle Slender Caloptilia stigmatella and Nut Leaf Blister Moth Phyllonorycter coryli.

After that things went downhill as the temperature dropped - just one more moth which I didn't manage to catch and a Green Lacewing Chrysoperla carnea agg. (actually they go brown in the winter, but they're still Green Lacewings not Brown Lacewings...).  It will be interesting to see how effective this method is when there are more moths about - my impression is that with a good beam it will make finding and catching flying moths easier although I'm not sure it actually attracts them to the light.  On the downside the light was noticeably dimmer after just a couple of quick circuits of the common so battery life doesn't seem particularly good, plus I'm not sure how comfortable it will be if it attracts lots of midges to my forehead!

The light was good at picking out certain types of fungi (although others were much harder to see than in daylight).  This Fly Agaric was nice and easy to identify.

This Stinkhorn was covered in flies - anyone know what sort of fly?

I'd tentatively identified these as Parasol Mushrooms though noted that they were smaller and in different habitat from other Parasols I'd seen.  Big thanks to James for putting me right... they are in fact False Death Caps.

I'd considered Penny Bun and Bay Bolete for these, but James thinks they're Bay Boletes...

At home that night I caught my first December Moth of the autumn.

This Currant Pug was a surprise being about a month later than my previous latest.

I find separation of Currant Pugs and Wormwood Pugs tricky - there are supposed to be differences in the prominence of the wing markings but I can't personally find any consistent differences.  The way they hold their wings also seems to be variable although size can be a good indicator on many, though they're close enough and with enough overlap that I now measure them all and check the genitalia of the ones that aren't clear.  With a forewing of 9.5-10 mm this individual was too small for Wormwood Pug but I checked it anyway.  The aedeagus was indeed that of a Currant Pug with three cornuti arranged in a band at the tip, so I'm sure the ID must be correct, but the 8th sternite was long and notched like on a Wormwood Pug!

Also late was my second October record of Common Marble Celypha lacunana.  There was also a bit of an Epirrita fest with 8 November Moths, 5 Pale November Moths and 2 unidentified (1 female, 1 escaped).  Also 2 Yellow-line Quakers, Barred Sallow and Angle Shades.

This cluster of 4 Harlequin Ladybirds seem to think my study is a good place to hibernate.

Next night there were Red-green Carpet, November Moth, Pale November Moth, 2 Yellow-line Quakers, Beaded Chestnut and 2 Angle Shades.

The last night of October produced a female Epirrita sp., 4 Feathered Thorns, Black Rustic, Green-brindled Crescent, Yellow-line Quaker and Beaded Chestnut.

November started very quietly on the moth front with Feathered Thorn and 2 Sprawlers on 1st, Sprawler and Beaded Chestnut on 2nd, just one Feathered Thorn on 3rd and nothing at all on 4th.

It continued poor for a week or so with just 1 Sprawler on 5th and 2 Sprawlers on 8th.  Slightly milder conditions on 11th produced Feathered Thorn and 2 Sprawlers and then the next evening produced my first Scarce Umber of the year along with Yellow-line Quaker.

Seven moths the following night making it the best night for a fortnight - 2 Feathered Thorns and 5 Sprawlers.  Things continued to improve on 14th with Light Brown Apple Moth Epiphyas postvittana, 2 December Moths, Pale November Moth, another unidentified Epirrita sp., 6 Feathered Thorns and 2 Sprawlers.

The species count was even better on 15th (though still short of double figures) with Light Brown Apple Moth Epiphyas postvittana, December Moth, November Moth, another unidentified Epirrita sp., 3 Feathered Thorns, Scarce Umber, 5 Sprawlers, Yellow-line Quaker and Beaded Chestnut. Also the caddisflies Rhyacophila dorsalis and Limnephilus lunatus plus the mirid bug Pinalitus cervinus.

Things then returned to normal for November with Feathered Thorn, 3 Sprawlers and Yellow-line Quaker on 16th, an Epirrita sp. and a Sprawler on 16th.  No more moths for a few nights but these fungi - I can identify the Candlesnuff (I think) but not sure about the others.

The next moths were Sprawler and Black Rustic on 20th followed by 3 Feathered Thorns and a Sprawler on 21st, December Moth, Mottled Umber and Yellow-line Quaker on 22nd, just Feathered Thorn on 23rd, December Moth and Angle Shades on 24th, Feathered Thorn and Scarce Umber on 25th and December Moth on 26th.  Also caddisflies on 26th: 3 Limnephilus lunatus and Halesus radiatus.

My first Winter Moth of the winter appeared with a Sprawler on 27th.

Unsurprisingly given the subzero conditions, nothing on 28th or 29th.  The following night, last night, fell below zero too but started fractionally milder, enough for a Winter Moth to appear at one of the windows.

And that, for the first time in months, brings me bang up to date!

  1. Congratulations on getting up-to-date. The Parasol-like fungus is False Death Cap. The swollen base (volva) visible on the second photo is a good feature of Amanita. Also the ring on Parasols is loose and floppy, plus there is a 'snakeskin' pattern at the bottom of the stem in Parasol. The bolete looks like Bay Bolete to me (now called Imleria badia - one of the large number of fungi with altered names thanks to DNA work). Key things to separate from Cep - Cep usually has a swollen stem with a net like pattern, Bay Bolete has straight with longitudinal fibrous look. Also Cep has smaller pores, these are too big. For this family pore size or pores per mm/cm is useful, as is checking if they bruise blue or red. Regards, James.

  2. Aha, thanks James. Very much appreciated as always, especially with all the explanation - brilliant.
