In the garden: Moths, Fungi & That Bramble

November 18, 2020

Two new moths have taken my total for adult moths here to 199 species:

There are fungi everywhere at the moment, but two pink ones in the garden recently are Coral Spot (Nectria cinnabarina)and Wood Blewit (Lepista nuda), both common enough generally but with rather few records locally. (None in VC104 on NBN for the latter.)

Meanwhile, it is looking more likely that the bramble in the last post is in fact Rubus subinermoides as determined by Alan Newton when he stayed with me in 2007, though I am waiting for a view on the pink petals.

Botanical Matters

It turns out that the bramble Rubus subinermoides recorded on Raasay and elsewhere in Scotland may in fact be different from R. subinermoides in England where the type species was first recorded. Amongst other things the large pink petals aren’t right. Those more skilled than I in batology will sort this out – it may be that a new microspecies will be recognised.

These pictures are from one of these plants on my drive yesterday:

I also spotted a single tree of Acer saccharinum (Silver Maple) in Inverarish. It was planted maybe a decade ago and is doing well, though last weekend’s storm did some damage.

Recent Sightings

October 29, 2020

An excursion to Skye meant I happened across Tropaeolum speciosum (Flame Nasturtium) sprawling over gorse near Lynedale.

This is a first for VC104, the sixth this year and, like most of the others, not a native.

Here at home, a caterpillar climbing up the outside wall of the house unexpectedly turned out to be that of a Small White butterfly. Green-veined Whites occur in huge numbers, but I have never recorded an adult Small White. Phil had some freshly-emerged adults in Sleat earlier in the year, so they are clearly now breeding locally.

Following the unsuccessful determination of an Epirrita moth recently, This morning I had two Autumnal Moths (Epirrita autumnata). This is most probably what the previous one was too.

Meanwhile, I am hoping for help with this Cranefly which is probably Tipula pagana.

October Moths

October 19, 2020

The total number of moth species I have recorded at home as adults has reached 197. New this month have been Feathered Thorn, Green-brindled Crescent, Large Wainscot and November/Autumnal Moth. The last was an Epirrita species which often need dissection to distinguish Autumnal, Movember and Pale November Moths. This was one such.

October Plants

October 19, 2020

Solanum nigrum (Black Nightshade) has been recorded at Cleadale on Eigg – a first for VC104.

There are recent records from islands to the south, outside my patch – Coll and Colonsay.

Nick has found one or two more locations for Ulex gallii (Western Gorse) – one needs checking as only spotted from a moving vehicle.

In Kilmore, Sleat, I found a churchyard full of flowering Hieracium (Hawkwed). I would suggest that it had been mown and then flowered late, but across the road in very rough ground there were one or two specimens of the same plant, also flowering. I have sent a specimen away for determination.

Hawkweeds in October

Later: David McCosh says, “Your plant cannot be identified to species. There are many plants occurring throughout the UK which are currently undescribed and are known collectively and informally  as  H. exotericum agg. They share certain characters such as having a rosette, usually 0-1 cauline leaf, and predominantly glandular peduncles and phyllaries. S & M warn that all plants akin to these are plastic in their growth and should not be collected after mid July!”

Mines, Galls and Microfungi. Part 2

October 19, 2020

In my last post I had meant to include this smut on Bluebells. It is common enough in this part of the world, but under-recorded.

Colletotrichum liliacearum on Hyacinthoides non-scripta (Bluebell)

In Broadford I found Venturia populina on Populus trichocarpa (Western Balsam-poplar). Bruce says it is “fairly common up here” but there is only one Scottish record on NBN – and that is incorrect as the host is given as Aspen.

Venturia populina on Populus trichocarpa

In Ardvasar there were Red Campion capsules with small holes near the base. I have forgoten what does this and hope someone will remind me…. maybe the moth known as The Campion?

Silene dioica

On one of the capsules I spotted this:

Unknown on Silene dioica capsule

It is very small but looks a bit too organised to be just miscellaneous junk.

Nearby there was a Leycesteria formosa (Himalayan Honeysuckle or Pheasant Berry) with lots of leaf mines.

Mines on Leycesteria formosa are caused by flies that traditionally mine Lonicera periclymenum (Honeysuckle) and I sometimes find them difficult to tell apart despite excelllent guides at UKflymines and Plant Parasites of Europe. Anyway, these images found their way to Barry Warrington who runs the National Agromyzidae Recording Scheme and he says they are caused by Chromatomyia lonicerae.

Mines, Galls and Microfungi

October 13, 2020

By the front gate there is a small Hawthorn tree (Crataegus monogyna). Yesterday I spotted a small moth larva that turns out to be a young Light Emerald.

Light Emerald larva

Apparently this species overwinters as small larvae lying flat along stems of the food plant. As you can see the larva has a fringe of hair-like projections hanging down from the sides.

Also on the Hawthorn a couple of leaves had been spun together with silk and inside was another moth larva. The identity of this one has not yet been resolved.

Before I left the premises I noticed a fungus on Solanum dulcamara (Bittersweet) which Bruce tells me is Alternaria solani.

This is not entirely good news as this fungus causes Early Potato Blight and we grow quite a lot of potatoes.

Moving on a couple of hundred metres to a strip of woodland by the Arish Burn, I noticed some leaf mines on Stachys sylvatica (Hedge Woundwort) caused by the true fly Amauromyza labiatarum.

and a little further on a Hazel (Corylus avellana) had leaf mines made by two different micro-moths.

Also there was a springtail, Entomobrya nivalis (sometimes called Cosmopolitan Springtail), though I almost missed it and have no worthwhile image to share.

A little further on there were galls on Ranunculus repens (Creeping Buttercup) caused by the fungus Urocystis ranunculi

I am grateful to various folks for identifying and confirming many of the species shown here: Bruce Ing, Roy Leverton, Murdo Macdonald, Stephen Moran, Nigel Richards and Mark Young.

A Few Minutes with an Alder

October 6, 2020

Yesterday, I spent a few minutes with my camera at an alder by my front gate. It turned out rather well….

This is the larva of the sawfly Platycampus luridiventris with no records on NBN for the west of Scotland. Thanks to Chris Johnson and Ian Andrews for i.d.

Platycampus luridiventris

This shows larvae of two more sawflies, the free-range one being Hemichroa crocea with just nine Scottish sites on NBN. Thanks Seth for i.d.

Hemichroa crocea larva plus one

This mine is caused by yet another sawfly, Heterarthrus vagans, which is more widespread but with no records for VC104 on NBN:

Heterarthrus vagans mine

On the other hand, it is a true fly, Agromyza alnivora, that causes this mine. I have recorded this before on Raasay, also in October.

Agromyza alnivora mines

Not counting two common galls caused by gall mites, my last find was of this leaf roll caused by the micro-moth Caloptilia elongella (Pale Red Slender). This is probably not uncommon but the only previous Skye/Raasay records I can find are from 1979 and 1998. Thanks to Seth for i.d. and Tony for confirming there is no other Scottish candidate for such activity.

What this shows most is how under-recorded our area is for inverts.

Mock-orange

October 6, 2020

Seth has spotted a Mock-orange bush near the river at Budhmor:

The underside of the leaves are pretty hairy suggesting that it is one of the hybrid groups, in which case full identification will have to wait until there are flowers next year.

More Plant Matters

September 25, 2020

Seth had a good day on Wednesday, finding two plants that are new to the vice-county. Firstly, Persicaria wallichii (Himalayan Knotweed) has encroached onto the road verge from a garden near Loch Bay House in Waternish:

One of the key fatures of this species is the unequal petals:

Then he spotted Poterium sanguisorba subsp. balearicum (Fodder Burnet) beside a track at Edinbane.

This plant is closely related to Poterium sanguisorba subsp. sanguisorba (Salad Burnet) and as the name suggests, used to be grown for fodder. However, it has also been included in “wildflower” seed mixes.

Meanwhile, Joanna has spotted Ulex gallii (Western Gorse) at two new sites on the Harlosh peninsula. This is a pretty rare plant on Skye though the golden yellow flowers now in evidence (with associated withered flowers rather than buds) make it stand out from a distance.

Ulex gallii (Western Gorse)

Mostly the comon Gorse (Ulex europaeus) is not flowering at the moment but a few pieces are.

Ulex europaeus on left and Ulex gallii on right

Amongst other differences, in U. gallii the flowers are smaller and deeper yellow and the calyx has appressed rather than spreading hairs.

Yesterday I went to see these sites with Joanna and Julian and thus encouraged, I managed to re-find a 1998 site for U. gallii near Lonmore.
