Nature Notes from Argyll
(and occasionally other places)
Tue 28 Apr 2009 Kilmartin
This month's Seil Natural History Group recording walk took us
to Kilmartin where local resident Alan Hawkins led us on a route around
Barr Mor on a fine spring day.
This Garden Tiger caterpillar was one of many that we met with, and Drinkers too
The female Emperor Moth at rest on the heather had probably newly emerged from
A single Marsh Fritillary caterpillar was found. They are
not otherwise known from this location. I wonder how far an individual
caterpillar can travel; it surely can't have been hatched too far away, but
where exactly is a mystery. The Brown Silver-line moth is common in May
and June; it was the first I'd seen this year.
Copse Snails were out in numbers, and a Netted Slug slithered
through the grass. A Brown-lipped Banded Snail was also seen.
Wolf Spiders were running about everywhere. The first 7-spot Ladybird
of the year was spotted, and several Dor Beetles.
A colony of the ant Formica lemani found under a stone.
Lasius flavus was also found. The moss with the apple-like capsules is
This is the mushroom Omphalina fulvopallens, which is actually a
lichen. At its base are green bobbles, shown in the RH pic through
the microscope. These are the lichen thallus and contain algae. Most lichens are ascomycetes and have fruitbodies like
miniature cup fungi (the familiar apothecia) but this one is a basidiomycete, so
its fruitbody is a whopping great mushroom.
When the meeting was over I visited a gorge in the area which had old records for Townhall Clock and Alternate-leaved Golden Saxifrage. The latter was soon found but it was a long search for the Townhall Clock, which is shown in the LH pic next to a Celandine leaf. The Saxifrage is in the second pic with a Townhall Clock leaf in the top right corner. There were several other lime-loving plants in the gorge, which would be rewarding to visit later in the year.

A patch of Bog Violet growing among Sphagnum in woodland.
Three-veined Sandwort, whole plant and close-up.
Orange Tip butterflies are on the wing now, laying eggs on Cuckoo Flower stalks. Examine enough and you will find one.
The ants are Formica lemani again. I was puzzled to see huge numbers of them over an area of 2 sq metres, almost as thick on the ground as when you find a colony under a stone. But they were all running about in the open, among moss, Dog Violets and dead leaves, with no sign of any "nest". Have not seen anything like this before. Until now, always dense colonies under stones or thinly spread out in the open.
There are also a lot of Bee-flies about, mostly on Dog Violet
flowers, but I couldn't get a good photo of one. Also many bumblebees
and hoverflies, including Rhingia campestris. Saw another 7-spot Ladybird.
The Blunt-tailed Snake Millipede, Cylindroiulus punctatus, in
rotting wood on the ground. A common woodland species. The rust
gall on Valerian is Uromyces valerianae, which is also common, but has to be
microscopically distinguished from the very rare Puccinia commutata.
A couple of plants from beside the River Awe path, very close to
home. Intermediate Lady's-mantle and Wood Speedwell.
