Early February at Home

February 9, 2021

There is a lone curlew on the shore. I think there was just one this time last year – perhaps the same individual. Recently, there have been a flock of Purple Sandpipers, Turnstones and a pair of Goosanders to add to the usual Red-breasted Mergansers, Mallards, Eider, etc.

I have recorded Rhododendron Bud Blast before. Then it was called Pycnostysanus azaleae, but now it is Seifertia azaleae.

Several galls are present on small sallows along the road. I opened one up and found it to be caused by the gall midge Rabdophaga salicis.

Early one morning, I found this little chap in the bathroom, Amaurobius similis or perhaps A. fenestralis :

We are having a period of cold weaher but escaping the serious snow affecting much of Scotland.

The weather and lockdown have limited activity considerably, but I have managed a few things such as second records for Raasay for Cupressus lawsoniana (Lawson’s Cypress) and Olearia macrodonta (New Zealand Holly), the former planted, the latter looking self-sown.

Yesterday the gorse near the shore yielded a spider, Metellina sp.

Metellina sp.

and several types of fly:

A window gnat. Sylvicola sp. probably S.cinctus

If it hadn’t escaped I could have got it to species as Seth pointed me towards a relatively simple key to the four British species. Also, there were a couple of Black Flies (I’m not tackling them), a common seaweed fly Coelopa frigida, though not so common in January, and a Heteromyza, possibly H. commixta but perhaps H. rotundicornis – it may be possible to sort this out with expert help. Later: confirmed as H. commixta.

Thanks to Seth (flies) and Katie (spider) for identifaction.

I had omitted Plantago lanceolata (Ribwort Plantain) and Ranunculus repens (Creeping Buttercup) from my list of weeds flowering in the garden. Both have been flowering for some time, but now I can add Conopodium majus (Pignut), Galium saxatile (Heath Bedstraw), Trifolium repens (White Clover) and Veronica serpyllifolia subsp. serpyllifolia (Thyme-leaved Speedwell). The last flowers are on the Ficaria verna subsp. fertilis (Lesser Celandine); I am not sure that it will quite make June.

I fell over a large toad on my way to turn on the moth trap a few nights ago, but my other recent animal records have involved arthropods. This Ichneumon is Ophion sp., but that is as far as I am going as it is a very tricky genus, and the taxonomy is in flux. Even if that were not so, it would undoubtedly challenge my skills to sort it out.

It has been a good couple of days for micro-moths with my very own Large Longhorn (the arrows show the end of the antennae, explaining the vernacular name):

Nematopogon swammerdamella

plus three others, two of which I had not seen here before:

A fly I caught yesterday turns out to be Delia radicum known variously as the cabbage fly, cabbage root fly, root fly or turnip fly. Thanks, Laurence. Whilst pleased to have the first record in VC104 on NBN, I am less than fully delighted given we have just planted out all our Brassicas.

The Goat Willow (Salix caprea) out the front is developing galls that I suspect are caused by the gall wasp Euura pedunculi.

and not far away an alder (Alnus glutinosa) has the early stages of Alder Wrinkle gall caused by the fungus Taphrina tosquinetii. Compare the size of the infected leaf with normal leaves.

A spider in the polytunnel turns out to be a Toad Spider or Walnut Orb-Weaver (Nuctenea umbratica). Thanks, Katie.

Last Sunday a young otter was exploring our garden – something we have never seen before, though we see them beyond the garden on the shore and in the sea. There has been a Great Northern Diver in the bay for some time and, as it is May, we can hear cuckoos.

I managed to identify a harvestman – probably the easiest to recognise with its spiky headdress:

Megabunus diadema

and Bruce kindly identified a fungus for me that is growing on dead Euphorbia griffithii (Griffith’s Spurge) stems as Phomopsis euphorbiae. It is not the most photogenic of things, but there are only two records on NBN Atlas one of which is in Scotland by Murdo – identified by Bruce a few years ago.

Last night’s moth trap was very limited, but gave me my first Pale-shouldered Brocade of the year.

The Tutsan (Hypericum androsaemum) is nearly in flower:

and I found evidence of sharks in the garden.

The egg case of what is now officially known as the small-spotted catshark, will have been brought in with seaweed used to fertilise the vegetable beds, it has not decomposed over the winter as has most of the seaweed.

Yesterday proved a windy but sunny and warm day for a walk in the Kinloch & Kyleakin Hills. I had hoped to find Epilobium anagallidifolium (Alpine Willowherb) and Gnaphalium supinum (Dwarf Cudweed) from slightly vague records made last century, but it was not to be.

There were masses of Lycopodium clavatum (Stag’s-horn Clubmoss) for over 2.5km along the track and the dwarf version of Goldenrod (Solidago virgaurea subsp. minuta) higher up. I am not consistent about recording the latter as it seems to me to me just that – dwarfed by exposure.

I was surprised to see that I had recorded Equisetum sylvaticum (Wood Horsetail) for the first time ever in NG71 and also the first post-1999 records for Equisetum fluviatile (Water Horsetail) and Equisetum palustre (Marsh Horsetail), earlier records being for just “NG71”.  I knew NG71 needed more work this season but had forgotten the apparent absence of horsetails.

Up the top there was this harvestman, probably Mitopus morio (Thanks, Seth) with a mite attached – possibly Trombidium breei.

Our first cuckoo of the year woke me up at 0450.  April 23rd is a popular date for the first cuckoo at West Suisnish.

For those living further south, a black-headed gull will be a common sight, but not here:

This little spider is Textrix dendiculata, the toothed weaver (thanks for i.d. Gemma) and was basking on the outside of the house:

The moth trap has been out a few times with Hebrew Character moths being by far the most frequent but this Early Thorn was nice:

and Seth has kindly determined this carabid beetle from the bathroom basin as Pterostichus nigrita:

The moth trap a few days ago attracted 28 moths including this micro that I have not had before:

Agonopterix ocellana

Agonopterix ocellana

which has been given the name Red-letter Flat-body. Names for micro-moths do not seem to have caught on – I think I can see why….

This spider is, I think, Tegenaria domestica , the Common House Spider – though with no records in VC104 on the NBN Atlas. Later: Hayley tells me that specimens are needed to confirm the species of Tegenaria so this one will have to remain as Tegenaria sp.

Spider 180407

Thanks to Seth for both these identifications.

I have also been finding River Limpet (Ancylus fluviatilis) and Water Cricket (Velia caprai) when out and about having had these brought to my attention by Seth.

Christmas Day and Boxing Day

December 27, 2017

 

Before the snow came, late on Boxing Day, I spotted these. The moth and a spider that Hayley has confirmed as Segestria senoculata following Neil’s suggestion that it might be that, were on the outside of the garage.

 

 

 

A Harvestman in the Garden

June 24, 2017

I think this is Leiobunum rotundum:

Harvestman 170624

Harvestman 170624 Body

It was on the outside wall of our house today. it looks like this species if one compares it with the images here.

It could be good to have  comment from someone more knowledgable about these…..

There is a 1979 record from Portree on the NBN.
