Callitriche brutia   Ceutorhynchus contractus agg leaf-mine on Cochlearia officinalis agg

If you take the path up the hill in the centre of Easdale Island, about halfway up you pass a steep-sided pool filled with green stars - the floating rosettes of Pedunculate Water-starwort.

This leaf-mine on Scurvy-grass is very intruiging.  It seems to be that of a weevil, either Ceutorhynchus contractus, which is common but has not been recorded on Scurvy-grass in Britain before, or its very rare relative Ceutorhynchus insularis, which is only known from Scurvy-grass, but is also only known from a couple of islands off Iceland and a couple more in the St Kilda group.  It isn't going to be easy to find out which of these species we have, as the adult weevils are very tiny.

Rainbow at Ganavan   Rabdophaga rosariella galls on Salix aurita

Rainbow at Ganavan, from the car park.  This visit produced a new species for Britain.  These bud galls on Eared Willow belong to Rabdophaga rosariella, a gall-midge that had not been recorded from anywhere in Britian since 1932, and which had been discredited as a separate species but is now revived thanks to this find.  An article about this by Dr Keith Harris will appear in the next issue of Cecidology.

Trentepohlia abietina on Acer pseudoplatanus   Ascocoryne cylichnium

A Sycamore trunk turned bright orange by the alga Trentepohlia abietina, and the lurid purple cup fungus Ascocoryne cylichnium on a rotting stump.

Cladonia polydactyla   Lipoptena cervi

The bright red fruits of Cladonia polydactyla growing on the ground among heather.  The fruits start out brown, as in the lower right, and then turn red beginning with their tips.  The insect is a Deer Ked that landed on my coat.  It's a newly-developed adult that will lose its wings when it finds a deer, or perhaps it thought it had found one.

Halyzia 16-guttata   Ganoderma australe

You don't see many ladybirds at this time of year but this Orange Ladybird was still visible, if not exactly active, on a fencepost.  The tough woody bracket fungus on Beech is Ganoderma australe.  Some brackets had a covering of brown spores from the one above.

Gallinula chloropus   Clavulinopsis fusiformis

The Cemetery Loch had several Little Grebes, making their accelerating trill sound, 2 Mute Swans, several Tufted Duck and this Moorhen.  And remarkably no Mallards.

The club fungus Clavulinopsis fusiformis, or Golden Spindles, was on a NW facing slope in a birch wood.

Lasius flavus   Pannaria conoplea

I've taken to looking for ants after discovering how few records there are for this part of the country.  Amazingly the first 7 colonies I found produced 5 different species.  These were Formica aquilonia, F lemani, Myrmica ruginodis, Lasius niger and L flavus, which is shown above.  All these finds involved turning over stones, apart from the F aquilonia (Scottish Wood Ant) which had a few brave souls patrolling the nest surface and even one or two exploring a nearby rockface.  In the summer it will be a lot easier as ants of all kinds will be out foraging.

Stereum hirsutum   Motacilla cinerea

I'm sure we've had both these species several times before but I find the fungus Stereum hirsutum very photogenic as it never looks the same twice.  Here it's lying flat on its back instead of sticking out like a bracket.  Some bits had the top slightly peeled forward to show the hairy zoned upperside which is usually the most noticeable part.  The Grey Wagtail was preening in a small woodland burn, and flew high into a tree after I took the picture.  This was quite a surprise, as I don't think I've ever seen one go higher than a fencepost before.

Marchantia polymorpha ssp polymorpha   Calocera viscosa

The liverwort Marchantia polymorpha was carpeting an extensive area of muddy ground among rushes.  The fungus Calocera viscosa was on a mossy mound in a forestry plantation.  This species looks as if it belongs among the club fungi (like the Golden Spindles earlier) but is not closely related to them and is actually a jelly fungus, with a slippery feel.

Lycoperdon perlatum   Cygnus cygnus, juvenile

Common Puffballs that have opened up to release their spores, beneath trees by a shady path.

Sat 15 Nov 2008 Seil Island

On a Seil Natural History Group walk to Ardencaple, we saw this young Whooper Swan, a winter visitor, not often solitary.  Other good sightings were Greenshank and Goosander.
