Kids have fun with flowers and butterflies

Last weeks mini wildlife adventure at Kilnaughton was a great afternoon. Lots of shells, big and small were found on the beach, and a whole range of strandline treasures, hard, soft, lived in, those which made a sound and those which smelled of the sea.

We followed this up hunting colours for our colour pallet and with some minibeast hunting up in the dunes, where we found soldier beetles and four different types of butterfly along with colourful moths too.

This Thursdays mini wild adventure (28th July) comes with double helpings, we are off to Jura in the morning to join the Jura Kids club at 10am to look at flowers and the insects and butterflies that visit them.  Then in the afternoon we will go in search of more flutterby's and introduce the children to the wonderful spread of flowers and orchids at Killinallan dunes.
We will aim, weather permitting to undertake a butterfly count for 'The Big Butterfly Count' for Butterfly conservation too.
The activity is free to all

Geology Walk at Kilchiaran 24 July 2016

   The rain stayed away until 4 and the tide was very low - a great opportunity to get into the 'billion year gap' at Kilchiaran Bay. 
   12 intrepid explorers engaged in a spot of coasteering to scramble into the cave on the left-hand side of the bay where the sea has eroded a gully along the 'Kilchiaran Shear Zone'. This fault zone separates the 1,800 million-year old pink gneisses and green metabasites of the Rhinns Complex from the younger (probably c. 800 million-year old) laminated metasiltstones, slates and cream coloured metasandstones of the Colonsay Group.
   The group also had a good look at some striated ice-sculpted bedrock dating back only about 25,000 years to the last Ice Age when Islay was covered in about 500m of ice and pebbly sands with flints deposited when the ice finally melted about 15,000 years ago.
   The group were excellent Mesolithic flint beach-pebble hunters and gamely enjoyed more role playing as Dave had them lined up in a time-line across the beach with various 'volunteers' playing the parts of the 'big bang', cyanobacterial green slime, dinosaurs and stone-age man along with the various rocks of Islay.

Rambling around Ardnave Sunday 17th July - next, the Billion Year Gap!

The weather was kind yet again, despite our ramble occurring just before this week's heatwave! Our intrepid party of 11 set off clockwise around Ardnave point, encountering lots of wildflowers on the way, including Bog Asphodel, lots of Lady's Bedstraw and Pineapple weed. We investigated the smell of these last two, commenting on the pineapple-like appearance of the flower, as well as the smell of pineapple, and the ancient use of lady's bedstraw as a flea-repellent - in the past, the dried plants were used to stuff mattresses as the coumarin scent of the plants acts as a flea killer - hence the name. It obviously doesn't repel moths, as shown by this photo from the other week!

You'll find a full list of what we saw below.

Join us too this Sunday 24th July for a Geology rAmble at Kilchiaran entitled 'The Billion Year Gap', where we'll be looking at some of the oldest rocks in the world! You'll find that within a few metres is a billion years of geological history! Mindblowing. The walk will be led by David Webster whose knowledge of Islay's rocks will enthuse and leave you awestruck. Meet at Kilchiaran at 2pm: please park responsibly either in layby by the old chapel or by the farm track with the information board (please do not obscure access). The walk will last c.1.5-2 hours, and there will be plants and other natural delights to discover too. We have a small charge to help towards the running of the Trust: £2 for members and £4 for non members. See you there!

Plants: ragged robin, red bartsia, red clover, white clover, selfheal, meadowsweet, purple loosestrife, silverweed, marsh ragwort, germander speedwell, yarrow, yellow flag iris, bog asphodel, lady's bedstraw, common storksbill, spearthistle, marsh thistle, lesser meadow rue, harebell, bog pimpernel, mint, wild thyme, birdsfoot trefoil, mouse ear hawkbit, orchids.

INHT nature rAmble to Dun Nosebridge 10th July

It rained in the morning and threatened to be wet for the afternoon, but the skies began to brighten at lunchtime and the MET office radar images said the last of the rain had passed. All set then for another Sunday rAmble, so despite the weather prospects and the competition with a certain tennis match that afternoon, I went forth in anticipation - would anyone be interested in the walk?  Happy to say 3 folk were keen and so glad they were as it turned into a lovely warm afternoon, the sun appeared, the ground was moist and warm, and the butterflies were already on the wing and visiting the flowers.  Whilst waiting at the bridge my eye was caught by a bush/small tree on either side of the bridge tree with newly developing berries. I could not place the species (I do pride myself on knowing most of our native trees very well) so it was a puzzle.  On my return I checked through a number of tree guides and eventually found it to be a Himalayan Tree-cotoneaster (Cotoneaster bullatus), an introduced, naturalised species, and not recorded on our database!

Cotoneaster bullatus
Sessile Oak
The walk to Dun Nosebridge takes a route through woodland with a nice mix of tree species, hazel, birch, sloe (blackthorn) and some lovely mature Sessile Oak.  We chanced upon a small family party of Long-tailed tits, always a joy to see.  There were Speckled Wood butterfly, Meadow Brown, Green-veined White, Small Heath and one chance sighting of a still (but only for a split second) Dark Green Fritillary.  A few dragonflies quartered about with a Golden Ringed slow enough to identify.  There were many Six Spot Burnet moths, obviously the time of the season for them.  Plodding slowly but purposefully across the track were the occasional Dor Beetle heading in search of dung.

6-spot burnet moth
The ramparts of the old iron age fort held the most variety of flowering plants: Thyme (including some white flowering clusters), Birds-foot Trefoil, English Stonecrop, Sorrel, Tormentil, Lady's Bedstraw, Self Heal and a good look was had at the three main thistle species, Creeping, Marsh and Spear.  Amongst the spikes of the thistle heads were soldier beetles and harvestman spiders.  Great views from the ramparts down to the River Laggan below and nearby: Neriby Hill had Buzzard, Hen Harrier and Raven all flying over.

Beetle and harvestman - can you spot both?

The last puzzle species yet to be identified was a very large hoverfly feeding on the creeping thistle, a good look through the Trust library is needed.

A very pleasant afternoon walk in good company, and still back in time to watch the end of the tennis :-)

Seashore family activity a hit - bring on the Moorland Magic!

Great fun was had on our first Mini-Wildlife Adventure of the holidays last Thursday, with a crowd of over 30 children and accompanying adults all joining our merry band of explorers on a Seashore Safari at Port Mor.  It was a good low tide too on which to look for the creatures of the sea. The children searched in rock pools, turned over seaweed and rocks on the lower shore  and scooped through the water with their nets. Any finds of creatures and beasties not fixed firm or attached solid to the rocks were put carefully in the trays for a better look. We got prawns, common shore crabs, hermit crabs, common periwinkle, smooth periwinkle, grey topshell,, limpets, barnacles, one solo Shanny and a small sea stickleback.

Seashore fun at Port Mor

Our next adventure (14th July) will take us to the magic moorland where the 'bleak' landscape will be viewed through enlightened eyes, to see the wonder of colour and form which make up this wondrous habitat. Insect-eating plants, and hopefully bright weather for butterflies and insects. Meet at 2pm in the RSPB hide car park at the Loch Gruinart reserve. Wellies advisable but not essential. 

Our family activities are running in conjunction with the Islay and Jura Toy Library again this season.  Funding for the activities has been sourced from Foundation Scotland so there is no charge, but donations are always welcome. Fiona McG

Moths and orchids at Killinallan

Well compared to yesterday's weather, Sunday's wasn't bad at all! Our group of 15 hardy explorers headed out to Killinallan dunes to see what wildflowers we could find, and ended up seeing lots more besides! As we walked up through the marram grass we spotted a beautiful Small Elephant Hawkmoth on the adundant yellow Ladies' Bedstraw, and a lovely furry-looking Drinker moth:

Also spotted were a Common Blue butterfly, plus numerous 6-Spot Burnet moths (including the cocoons from which they'd emerged).

On to the flowers then, and two species stood out as coming into flower early - Devil's Bit Scabious (the food plant of the Marsh Fritillary butterfly) and Autumn Gentian which is, as the name suggests, an autumn flower - perhaps our warm summery May followed by a cooler June has brought some plants on early.

Autumn Gentian

And finally, the orchids. Lots of Pyramidal orchids were seen, plus a variety of others - see list below for all that we saw.
