Winter Moth

Thanks to Brian Neath for the identification and for the information that it is the first Winter Moth record for Skye/Raasay since the Carbost Rothamsted site operated between 1966 and 1979.  He goes on to say “The “winter” moth species tend to be under recorded due to the lack of resident moth trappers and the fact that visiting moth enthusiasts don’t tend to visit during these months.  Northern Winter Moth is very similar but slightly larger and paler and only occurs during October to mid-December.  Other winter species include December Moth, Scarce Umber, Mottled Umber and Dotted Border.  All have flightless females except December Moth.”

Bruce Ing tells me that the slime mould on our  lawn is Physarum cinereum.  This is a new record for v.c. 104 and apparently the first slime mould recorded from Raasay.

Carole Millington sent me some images of a fungus that Dave Genney has identified as a false morel, “most likely Gyromitra esculenta, a spring species, but possibly G. infula which is more of an autumn species”. Since they were spotted near Dunvegan Castle in October, perhaps the latter is more likely.

Philip Sansum sent me an excellent set of nearly 400 Skye records from early October and Robin Walls sent me over 800 records from time spent on Skye around the Field Meeting in July.  Tantalisingly, he recorded Arum maculatum (Lords-and-Ladies) but has since had possible second thoughts – I know the feeling well! This would be the first record localised to better than a 10km square and the first record since 1950. An early target for 2012.

Sarah McGrory sent records from Rum including many for Arabidopsis petraea (Northern Rock-cress).

A report for the second half of 2011 has been put on my home page.

A few things I have missed:

In late August I sent some scat from Raasay to Roger Cottis who assures me it is hedgehog. This is the first Raasay record for hedgehog and if more than one are present, not good news for ground-nesting birds.  I wonder how it/they got here?

The swallows finally left a couple of days ago – 29th September I think. I counted about 40 a few days earlier on the wires by the house – the same as last year.

The specimen of ergot on Nardus stricta (Mat-grass) has gone to Kew as there is only a single collection on this host that has been databased at Kew. Martyn Ainsworth says “I’m sure it is Claviceps and it will be assigned to purpurea for now (although quite how the fungus has co-evolved with its different grass hosts is probably not fully worked out yet). The size of the sclerotia is likely to match the resources available hence large on Spartina and tiny on Nardus.”

Four curious “weeping” Salix purpurea (Purple Willow) trees were spotted by the old road not far from Broadford:

and a dozen black poplars have sprung up by the main road not far away:

Populus sp.

Yesterday there were several patches of slime mould on the lawn. I think this is Mucilago crustacea:

I had most hope of the Viburnum as we had not gone into the gorge where it was recorded, but  despite adding quite a few species to the July list for that tetrad, I could not spot any V. opulus.  The Lycopodiella was more of a forlorn hope as we had looked for it in July and the area of heather from which it had been recorded had clearly been burned not too many years ago. Again I failed.

On the western side of the Head I also failed to find the Saussurea but there was quite a lot of Dryas, which was the one I was most hoping to find:

All in all I added forty plant records to the four tetrads I visited.

I found an additional site for Carlina vulgaris(Carline Thistle) not far from one of the July sites:

and there were still a few flowers on the Silene acaulis (Moss Campion):

I found a moth that Brian Neath has identified as a Treble-bar, and there were Heather Flies (Bibio pomonae) about.  There was a colony of the solitary bee Colletes succinctus(Common Colletes) and I managed to get a photo of one:

Colletes

I spotted what appears to be Ergot on Nardus stricta (Mat-grass):

There were lots of fungi and I have asked Ern Emmet to look at these two which I think may be Hygrocybe cocccinea

Hygrocybe cocccinea?

and Lycoperdon perlatum

Lycoperdon perlatum?

The birds were the usual mix of buzzards, ravens, rock doves golden plovers etc., but I also had a fine sight of a peregrine.

I am planning one more go if we get any dry weather in September and then I shall be away for some time…..

Heather Beetle Damage on Eilean Tigh

We also found a large colony of the solitary bee Common Colletes (Colletes succinctus) that thrives on heather – another good reason to maintain a healthy heather population in the area.

I only found one of these species today, the gentian, which is subsp. amarella:

Gentianella amarella subsp. amarella

I hope to have better luck with the cinquefoil next May when it will be in flower.

There were some late-flowering primroses:

Primula vulgaris

and white-flowered Centaurea nigra (Common Knapweed):

White Knapweed

I checked up on the only known plants on Skye of Asplenium ceterach (Rustyback Fern), which were in good health:

Rustyback

The limestone pavement had plenty of Epipactis atrorubens (Dark-red Helleborine) and in some places there was Calmagrostis epigejos (Wood Small-reed) and Elymus caninus (Bearded Couch) growing together in the grikes.

Finally, a view of Loch Cill Chriosd from the south with lumpy foreground interest:

Brian Neath has kindly identified the images I sent him which included:
