Frosted Orange

I've commented before on the sometimes very appropriate and sometimes downright weird vernacular names given mainly by the Victorians to our moths. One I caught last night definitely belongs to the former category, even if it does nowadays sound rather like a delicious sweet! The Frosted Orange moth may not be a sweet but its name is a fitting description of this very attractive little insect. This is only the sixth record for the vice-county (Islay, Jura, Colonsay) and the fourth for Islay. The first two were trapped on the RSPB Loch Gruinart reserve in September 2010, then one was caught on Colonsay in August 2011, followed by another there in August 2013. In the same month, David Wood trapped one on the RSPB's The Oa reserve here on Islay.

Sunday rAmble - 24th August - Geology walk at the Oa

After a long run of wet and windy weekend weather our programme of Sunday rAmbles have been severely washed out. So this weekend with hopefully dry weather we are hopeful that this Sunday's fascinating geology inspired walk around the monument at the Oa and Dun Athad will attract interest from many quarters. David Webster led a fascinating walk at Kilchiaran last month and will interpret the billions of years of rock formation, some of the oldest rocks in the world are on Islay, formed over the South Pole!
Come along, meet at the RSPB Oa car park at 2pm on Sunday.
Cost £4/person; £10/family; £2 INHT members

Killinallan family activity 08/08/14

So it was a blustery and rainy day last Friday but against the weather the family activity continued. Although pollinators were few on the ground (although one common frog was very happy with the weather) in the rainy weather we were able to find many wildflowers still showing well, including eye bright, ragged robin, water mint, meadow sweet and harebells.

Out in force in the short grass were the grass of Parnassus flowers bobbing in the wind and looking none the worse for the rain. Although my ID skills helped me through most of the plants on offer at Killinalan I was lost for a few names to species I now remember so to correct that here are a few photos with their names below, forgive the image quality it was a rather miserable day and so I could only do the best that I could.

Basking Shark Tag

A Basking Shark tag had come off a shark affectionately known as Finly. Several people, including Lorna and I went in search of said tag - it was near Smaull Farm. The search area covered about 1 km of potentially dangerous terrain though and we did not risk going too far, although we had a thorough, futile scour of part of the safer area. Apparently the tag has been located (by satellite) on its way north - perhaps (and hopefully) Colonsay - so let's hope it turns up somewhere more accessible next time!

Butterfly Fun Day 2014

We had the best turn out ever for our indoor activities at our annual Butterfly Fun Day, but the poor weather put budding counters off for the big butterfly count at Killinallan. Those that did turn up were keen however and the final scores revealed that, for the first year in 3, the Meadow Brown came out as our most numerous butterfly, beating the previous years' contender (Common Blue) by about 15 to 0!

At the Centre we made delicious butterfly cakes, designed butterflies and made caterpillars and learnt about the lifecycle of a butterfly, aided by the Cinnabar Moth caterpillars which are growing well in our pavilion, having been bred from last year's chrysalises!

Many thanks to all for coming and especially to Niall and Lynda and Maggie for baking, enthusing and clearing up!

Swallow-tailed Moth

Only the fourth record for Islay (one each in 2000, 2001 and 2003), this beautiful moth with a 3-cm wingspan entered my trap last night, and, after being photographed, was released back into the garden.

Geology Ramble - Kilchiaran 20th July

A small band of budding geologists gathered for an insight into Islay geology, super old rocks and a fascinating explanation of how they were formed and how they got here, once formed over the South pole! David Webster provided the answers and managed to make confused brains understand how it all fitted together. A million years difference in the geology of the rocks south of Kilchiaran Bay and those to the north.

A new moth for Islay

In my trap last night was a Scallop Shell, an attractive moth which has not turned up on Islay before, while the only previous record for any of the three islands is one caught on Colonsay in July 2013.
With my thanks to Danny Arnold for correcting my original incorrect identification!

Kilnaughton flora and hoverflies

How come I've never really explored Kilnaughton dunes before? I was overwhelmed by how beautiful they are and found the most gorgeous display of Meadow Cranesbill and Meadowsweet I've ever seen. What a delight it was to hear the constant humming of bees and hoverflies enjoying the rich nectar of the bountiful flora of these dunes.

Sanaigmore rAmble - 13th July 2014

Last Sunday's ramble was a bright and sunny afair with a sociable mix of members and visitors. We did not roam far but enjoyed a host of flowers and butterflies. There was a broad spectrum of knowledge amongst the group, with botany, birds, invertebrates, inc. butterflies (which were enjoying the heat of the sun), fungi and geology.
Flowers: Monkey Flower; Bird's Foot Trefoil; Eyebright; Self Heal; Common Centaury; Autumn Gentian; Frog Orchid; Field Thistle; Fairy Flax; Hawkbit; Devils Bit Scabious; Bog Pimpernel; Lady's Bedstraw; Lesser Meadow Rue; Thrift. Invertebrates: Soldier Beetle; Dung Beetle larvae; Common Blue butterfly; Meadow Brown; Ringlet; Tortoiseshell; Dark Green Fritillary. Birds: Gannet; Chough; Oystercatcher; Arctic Tern; Rock Pipit; Ringed Plover. Geology: Flint; Gneiss. Looking forward to today's geology walk at Kilchiaran at 2pm. Fiona MacGillivray (Chair) This is the first time I have managed to get access to blog to post (via my old computer, new one doesn't like it) so apologies to those who like hearing about the rambles. This has taken an age to post so hope it works!

A Pond of Wonders

So a slightly delayed post about our pond dipping activity day at Bruichladdich. last Friday we met down at the Bruichladdich pier before traveling up to George's pond, a great little spot which became a great pond dipping experience. Before nets even got wet a few keen eyed pond dippers spotted some tiny froglets just in the grass around the pond, followed swiftly by a tiny toadlet, sparking discussion about the difference between the two, unfortunately these little fellas made an escape attempt whilst we were distracted by the other wonders we found. The activity started slow as the weather was hot and all the mini-beasts headed to the deeper regions, but a few clouds saved the day and with a few keen eyed netters we soon had trays over flowing with key species and a few monsters of the pond.
                                                                                                       












                                                   
So our first finds were the typical water boatmen, mostly greater water boatmen but these were soon overshadowed by the first water scorpion of the day, after which we would find a handful more including this monster specimen who probably should of had his own bucket as these veracious predators see everything on the menu including tadpoles fish and even our tiny froglets. This one soon made quick work of one of our damselfly nymphs another top predator of the pond with the alien like hinged bottom jaw similar to their dragonfly cousins, they hunt by ambush grabbing anything that strays too close.

One of my personal favorites from the day was this brilliant water beetle, One of my favorite things to find in ponds; their larvae rival the water scorpion for top dog in most ponds. Alongside the usual groups of beetles and insects this was already a good haul until a shout went up for an eel. A great find Immediately followed by another great find, a leech, these two together where unexpected and we were incredibly luck.

These capped our pond dipping day and after releasing the critters back to the pond it was back to the centre to return some very muddy nets, and to let clean some very muddy wellies.

Down on the shore in Port Charlotte

I have often been too pushed for time to properly get down on my hands and knees and delve in to the rocky exposed shore next to Port Charlotte beach. However, one sunny day last week, the opportunity arose. Apart from finding an abundance of  Dahlia Anemones, and releasing a deadly looking jellyfish into the open sea, we uncovered many exciting creatures, photographed below.

Mum's favourite, the Broad Clawed Porcelain Crab. Both these individuals were missing a claw each, testament to their fragile nature. Not often seen, this species is found at very low tides often under rocks under rocks! They are very good at clinging onto surfaces with their back legs, including your hand when it is time to return them!

Not two, but one Piecrust Crab which has recently moulted, leaving its old, paler armour behind. Be careful when handling crabs at this time of year, as moulting is in full swing and the shells take a while to harden, making them very vulnerable.

Sea Lemon. We found two on this occasion, both feasting on Breadcrumb Sponge, their favourite food.

Sea slug, possibly Grey Sea slug, which along with many other sea slug species, are busy laying eggs under rocks and seaweed at this time of year.

Camping and caves at Bagh an Da Dhoruis

Wow! What a trip this was! Two days away from toil and trouble; days when you have to pinch yourself to know you're still human and living on earth and not on some amazing Paradise. Of course, Islay can be utopian, or almost (there are always midges and clegs and tics to remind us of its earthly status). Those aside, however, and you're left with something so idyllic you want to invent a new word for the occasion. Walking from Bunnahabhain northwards and inland, we descended very steeply to the beautiful Bagh an Da Dhoruis where the sunshine and clegs welcomed us and the caves beckoned. Armed with a good torch and the gung ho attitude of our youngest two members, we set off to explore Islay's inner core. The intrepid need not read on. It was a belly crawling experience in parts with the wonder of stalactites and stalagmites, spiders, dead goats and cave pools bathed in sunshine. We went in about 200 metres to the rear of the cave's chamber where you could stand up in complete darkness and be afraid - very afraid! We emerged from the cave's birth canal onto sun-kissed sand and sea, gathered wood and had a banana BBQ before hitting the pillow. Of course we saw lots of flora and fauna en route:
