Butterfly Bonanza

A visitor to the island made it his quest to photograph as many butterflies as he could whilst on holiday here. He promised to send his photos to us upon his return. True to his word, here they are. Thanks, Tim!

Common Blue - Polyommatus icarus

Dark Green Fritillary - Argynnis aglaja

Speckled Wood - Pararge aegeria

Meadow Brown - Maniola jurtina

Small Copper - Lycaena phlaeas

Grayling - Hipparchia semele

Jaws Galore (the friendly version!)

We have recently had two reports of over 20 Basking Sharks in Loch Indaal off the Rhinns, Nerabus southwards. This is exciting news so keep your eyes peeled!

Seashell Workshop

Do you enjoy a walk on the beach? Do you find you can’t resist collecting seashells? Do you wonder what they all are?

I have been inspired since working on the display of shells at the Islay Natural History Trust (INHT) visitor centre many years ago to build up a collection of shells, most gathered from Islay.  So far I have recorded just over 110 species from Islay’s beaches and 129 in total from across the UK.  These range from the big Iceland Cyprina (up to 12 cm) which can live up to 100 years, the small but beautifully ornate Pheasant Shell to the tiny yet common Turtonia minuta (barely 2mm) which you probably unknowingly are walking all over, mixed up in the sand under your feet. 

I will be running a workshop and short talk at the Islay Natural History Trust centre on Sunday 4th September from 2-4pm (donations welcome). If you have an interest and would like to learn about some of the shells you have found anywhere in Britain, bring them along and get some tips on identification techniques. There’ll also be an opportunity to use microscopes and the chance to get your hands stuck in shell-sand. We’ll be looking at other beachcombing finds too – so bring along your other strandline treasures as well.

Why not go beachcombing at your leisure sometime before and bring along your specimens?

If you have a collection of your own from Islay or further a field then please do get in touch (  I would very much like to compare specimens and see if you have species missing from my list.  I am looking at photographing as many species as possible of all qualities, as a representation of all conditions likely to be found which will help aid identification.

Flora and Fauna at Killinallan, 29th August 2011

Only two people for today's windy ramble. Think we'll need to improve the advertising for next year. It's been interesting going back to Killinallan over the past few months and seeing the annual floral cycle take place. The orchids are now all gone and instead of being awash with pinks and purples, the dunes are a carpet of blues with Harebells and Devil's-bit-Scabious in profusion. Fungi is sprouting up all over the place as well - and so we welcome autumn!

Curlew, Raven, Oystercatcher, Great Black-backed Gull, Common Gull, Eider, Meadow Pipit, Reed Bunting, Pied (White) Wagtail

Grey Seals (singing)

Xanthoria parietina, Anaptychia runsinata, Lecanora Gangloides, Ramalina sp.

Lots of species - to be identified we hope!

Stone Age man on Islay

Red Admiral

There have been very few of these around this summer compared with past years - just two in my garden in the last two weeks. We'd love to hear of more records, and of Painted Lady, so please send us details via our Biological Records website (link at the top of the page).

Fungal Foray

We're breaking the record for the number of posts per day,but I don't want to leave anyone out and it's great having so many folk send in their records. Please keep them coming!

This latest batch is from Alistair Hutchison, a local man, and is more evidence I'm afraid of the onset of autumn - a veritable fungal foray. I'm afraid I don't know what the fungi are, but will seek help from the experts! NOW DONE AND IDENTIFIED. Thanks, Alistair!
Hygrocybe conica  - Blackening Waxcap

Volvariella gloiocephala

Polyporus squarmosus - Dryads Saddle (sorry-looking specimen)

Hygrocybe conica  - Blackening Waxcap

Carabus clatratus - Golden-dimpled Ground Beetle

I've been waiting for definitive identification of this previously misidentified (by me!) beetle. I'd thought it was Carabus arvensis, but it is in fact the superb Carabus clatratus, which for once has an English name - and a rather lovely and fitting one at that - Golden-dimpled Ground Beetle.

Moths from the Lawson family

The Lawson family are regular visitors to Islay and keen naturalists. They have borrowed the moth trap this week and sent us these photos. Thanks everyone!

Ear Moth sp.

Chevron - Eulithis testata

Burnished Brass - Diachrysia chrysitis

Autumnal Rustic - Eugnorisma glareosa

Rosy Rustic - Hydraecia micacea

Narrow-bordered Bee Hawk Moth

A representative of Butterfly Conservation Scotland was over last week surveying Marsh Fritillary caterpillars. He really liked our butterfly display! He's going to send more records, but for now sent in this great photo of a Narrow-bordered Bee Hawk Moth larva. Thanks Paul!

Walk to Stremnishmore

Whilst Fiona was exploring moorland at Upper Killeyan yesterday, I was not too far away, walking to Stremnishmore, a deserted farmstead on the Oa. There was a lot to be enthused about (despite lack of good lighting for photography), but I was particulary excited about these Marsh Fritillary caterpillars. These butterflies seem to have had a poor year, not helped no doubt by THE storm of 23rd May, so it was encouraging to see these critters swarming about. I only saw one web though.

Also saw this common ground beetle, Pterostichus niger.

Moorland Magic at Kintra

Fiona sent in this piece about yesterday's magic moorland session:

Moorland magic this Tuesday was attended by 10 very enthusiastic participants on a small area of moorland just 100m from the RSPB Upper Killeyan car park on the Mull of Oa. We investigated the hidden range of colour to be found if you get down low and really look, moorland is definitely not dull and boring. The Ling Heather is just beginning to bloom, but despite many flowering plants having set seed there was still a rich range of greens, yellows, pinks and autumnal browns but a distinct lack of blues.
A search for animal life revealed a great variety of invertebrates, spiders, leafhoppers, centipedes, beetles and some impressive grasshoppers including both common green and meadow grasshoppers. Unfortunately the weather was a bit cool and densely overcast so no butterflies although a moth was captured. We also found round-leaved sundews an insectivorous plant.
I am looking forward to next week, (unfortunately), the last activity of the summer when it will be beachcombing on Uiskentuie Strand.

Bumble Bee Blunder

Oops, how embarrassing! But no-one picked it up yet so it can't be that bad! The first bumble bee picture I posted is in fact NOT a bumble bee, but the hoverfly Eristalis intricarius. This is a large, furry hoverfly which resembles a bumble bee. Its colours are variable.

Basking Sharks

We've not had many reports of Basking Sharks yet this year, but here's one from some visitors - received by email with thanks.

On our first visit to Islay, we saw two basking sharks in the channel between Port Wemyss and Orsay Island on Saturday 13th August 2011. Wonderful experience, wonderful place.

Bumble Bee Foray

My latest thing is bumble bees but, despite the fact there's relatively few species found on Islay, I'm still finding it difficult to identify them! Yesterday I went for a bit of foray along the road to the Machrie Hotel. The verges abound with Black Knapweed and the air was full of the gentle buzzing of bees. I snapped away happily and managed to photograph two species of bumble bee. I've printed off some credit-card sized ID guides if anyone is interested or download from

Pond Dipping

It was pond dipping yesterday and it sounds like they had great fun.
Fiona writes:
A very good pond dipping activity today, 9 children, 2 families (visitors and locals), despite inclement weather. Some great catches, mainly from one lad who managed to catch two Greater Water Beetles and a fabulously sizeable Horse Leech which we had looping over our hands (see photos). Lots of water scorpions, greater water boatman, lesser water boatman, pond snails and right at the beginning a lovely little toad which was spotted before anyone trod on it!
We observed all the beetles and boatman breathing through their bottoms and baby leeches sticking to the white trays.
A very enjoyable afternoon with very enthusiastic youngsters.
