Minibeast Monday - Butterflies

 


One of the great delights of the Spring is the emergence of the butterflies. A moving kaleidoscope of colour amongst the freshly blooming flowers. Down around the Mediterranean you can find Plain Tigers and Swallowtails as well as a host of others. 


This is a gallery of the species that I observed in Crete over the many years that I spent there.



Up here in Cumbria, they are beginning to appear too. Some of them have overwintered, like the slightly battered looking peacock, but some have newly hatched, like these Small Tortoiseshells which are already courting. #courtship is one of the themes in this month's European Nature Almanack so I'd love to see your pictures.


Look out also for caterpillars. You will often find them on specific food plants. Swallowtails, for instance, simply adore fennel, whereas Small Tortoiseshells prefer a diet of stinging nettles.

If butterflies are your thing then here are a couple of books that you may like to take a look at, and an item that no entomologist should be without: a sweep net!  Butterflies and moths are also featured in The Quick Guide To Creepy-Crawlies on pages 40-41.






All of the books featured on my posts are now available to view, by category, on one page: Build Your Own Nature Library




All the best,


Steve

Glasson Moss and The Other Fossil Fuel

 


We all know the three major fossil fuels; coal, oil and gas but today we're off to a peat bog. Peat is sometimes referred to as the forgotten fossil fuel and is rarely used outside of Scandinavia and the British Isles. It's an amazing material formed by partially decayed organic matter and, what's more, it's terrific at storing carbon. So terrific that the International Union for the Conservation of Nature have calculated that peatlands store more carbon than all other vegetation types in the world combined. The important plant in this ecosystem is this Sphagnum moss. The green bits that you can see contain the usual photosynthesising plant calls, but underneath they have special, barrel shaped cells that soak up water like a sponge, thus creating the bog. Bogs are very acidic and only certain plants, like the Hare's-tail Cottongrass that you can see dotted about, can tolerate these conditions.




Another plant that loves these acidic conditions is Heather which is why we're seeing a lot of Oak Eggar caterpillars about. Despite its name (which derives from the fact that its coccoon is said to resemble an acorn) its preferred caterpillar plant foods are Heather and Bilberries. We also have a Wall Brown butterfly making a flying visit and a small moth hiding in the heather that I can't identify.





To stop our feet getting wet, volunteers have laid hundreds of metres of boardwalks, and as these warm up in the sun, Large Red Damselflies and Viviparous Lizards come out to bask. How do you tell a damselfly from a dragonfly? Dragonflies rest with their wings outstretched, damselflies fold them back in line with their bodies. (One of the many tips to identification that you'll find in
The Quick Guide to Creepy-Crawlies).




As we come to the edge of the bog we come into a small patch of Silver Birch. On some of the dying stumps of trees we have Birch Polypore bracket fungi growing. These grow almost exclusively on birch trees and are also known as the razorstrop fungus because that was what they were traditionally used for. And for those of you who don't remember the days before the disposable safety razor, razor blades used to resemble single blade penknives and had to be regularly sharpened by whetting the blade, back and forth on a strop. We also have a number of small beetles on the leaves. I haven't had them confirmed as yet, but I think that they are Heather Beetles, Lochmaea suturalis.




I haven't mentioned birds yet, but they've been about. Mainly Chaffinches and a few Blackbirds but for most of the morning we've been accompanied by the call of a cuckoo, the first I've heard this year. And for those of you who only read this blog for the birdie bits, here's a Wood Pigeon taking a bath on the track into the nearby village of Glasson.

Series 14 Springtime in Cumbria

 


Welcome to a new series of The Crete and Cumbria Nature Blog. Still in Cumbria, thanks to the necessary travel restrictions still in place, but I'm not complaining. Cumbria is a wonderful place to spend the Springtime. So, let's celebrate by looking out for the first signs of Spring, such as newborn lambs, primroses bursting through last years fallen leaves, trees and woody shrubs budding and flowering, and insects pollinating the plants as their blooms burst forth.



Continuing our railway theme from last week's imaginary trip on The Cockermouth Circle Line, our journey today starts at Keswick station and follows the old railway line towards Threlkeld. The line, which used to link Penrith to Cockermouth, was axed in the Beeching cuts of the 1960s, and is now a tarmacadamed walk/cycle track suitable for wheelchair users. Just listen to Spring beginning around the station with this symphony of birdsong.



The River Greta (which means stony stream in Old Norse) will be our constant companion on this walk, as it zigzags back and forth across our trail. There's a Woodpigeon down there, collecting sticks for what he laughingly thinks of as a nest. Whereas some birds construct intricate structures of grass, moss, wool and other materials, pigeons just seem to launch twigs at a tree and see what sticks. How their eggs and chicks remain aloft is one of nature's great mysteries.




There are ponds along the side of the trail, with Marsh Marigolds bursting forth. These are predominantly insect pollinated and have an unusual method of seed dispersal. When the seeds have matured they are surrounded by a 'splash cup'. When a raindrop hits the splash cup the seeds are bouced out. They are also surrounded by a spongy lifejacket so they simply float away from the parent plant. Like their relatives, the Lesser Celandine, which we have been seeing a lot of in recent weeks, their leaves are edible when cooked but poisonous when raw. (see Longlands Lake). And clumped together on the bottom of the pond we have frogspawn. You can tell that it's frogspawn and not toadspawn because of the way it clumps together; toads lay their spawn in long strings.




You'll have noticed that all the bridges, the tunnel and much of the infrastructure on this trail are brand new. In 2015, Storm Desmond produced such a torrent of water that all the old railway bridges were destroyed. Seeing the river so calm and peaceful today, it's hard to imagine the scale of the flood that could have wreaked such havoc. It took five years to repair the damage and the trail was only reopened at the end of last year. I've included a few pictures of fungi and lichens, not because they are signs of Spring, for they are with us all the year round. I just didn't want them to feel left out.


We also have caterpillars crawling about and this one features in my new series on
Steve's Nature Plus called Minibeast Monday in which I tell you a little bit more about the insects and other creepy-crawlies that appear in my blog posts. Much of the information is taken from The Quick Guide To Creepy-Crawlies which tells you who is related to whom, how to identify them in their various stages of life, and plenty of other interesting facts (like whether they are likely to bite or sting you). Everyone tells me that it's a very interesting and informative book but modesty precludes me from agreeing with them wholeheartedly. I still refer to it when I come across something I've never seen before.





I'll leave you with this beautiful picture of the River Greta flowing through the Lakeland pastures with a little Grey Wagtail bobbing around on the boulders. See you through the week on Steve's Nature Plus.


Happy Springtime,


Steve

Steve's Nature Quiz #29

Here's a butterfly that many of you will be familiar with, the Cabbage White, Pieris brassicae, but which of these is NOT a food plant for its caterpillars?

a) Cabbage, Brassica oleracea

b) Black Mustard, Brassica nigra

c) Caper, Capparis spinosa


If you answered c) Caper, Capparis spinosa, then up until the end of last month you'd have been correct but that was before the #CreteNature blog visited Sklavoi – Village of the Slaves. It was there that we observed the caterpillars of this butterfly happily munching away on Caper leaves and added a new piece of information to our knowledge of this very common butterfly. So now the answer is ALL are food plants for its caterpillars.

I can't promise you new discoveries every week but there's usually something to make you say "Gosh! I never knew that," as well as some beautiful scenery and a few laughs along the way. So why not join us as we stroll around the countryside of Crete poking our noses into bushes, streams and under stones to unearth some of the many wonders of nature? Just follow the #CreteNature blog.

Sklavoi – Village of the Slaves

When you look at a map of an area there are often a number of exciting looking places to investigate but at first glance Sklavoi does not appear to be one of them. Which is why I want to go there for I often find the most interesting things where they are least expected. For instance the connection between this little church down here, grasshoppers and the bomb disposal squad. The church is dedicated to St. Barbara, a young lady of Christian persuasion who's father was an out and out pagan. When he learnt of her conversion he went at her with a sword whereupon the wall of the tower (in which he kept her) exploded. Babs finished up, unharmed, in a mountain gorge alongside two very surprised shepherds. Her father pursued her, one of the shepherds betrayed her and he was turned to stone for his treachery. Not only that, his entire flock was turned into grasshoppers (which seems to have been quite popular in the past – see Chrysopigi - Source of Gold). She was caught and tortured and about to be beheaded by her father as a final punishment when he too was detonated by a bolt of lightning and Barbara escaped. In honour of her going out with a bang as it were, she is now the patron saint of all those who work with explosives.

I am also intrigued by the village name for Sklavoi is Greek for slaves and Crete was never big on slavery. What slaves there were seem to have been reasonably well treated and it was here in Crete that the tradition of the 'servants-day-off' where the slaves were waited upon by their masters probably first originated [1]. We are not the only animals to indulge in a bit of slavery. These ants down here are workers busy dismembering a dead gecko. These particular ants were born in the colony but the Blood Red Ant of Northern Europe, the U.S. And Asia will raid the nests of other ants and kidnap the pupae and larvae and enslave them. I sometimes wonder if we humans were ever the first to do anything.






Let's wander down out of the village and see if we can find any autumn flowers. Quite a variety in the environs of this magnificently twisted old olive tree. Quick quiz: look closely and see if you can spot the odd one out. Did you spot the little Mirid Bug peering over the edge of the right hand petal of the yellow Squirting Cucumber? How about the Southern Green Shieldbug nymph nestling between its fruits below? Or the pair of beetles investigating the centre of the Autumn Crocus to the left? A little Autumn rain, the flowers come out, the insects appear and nature's larder is re-stocked once more. The only one without an entomological attendant appears to be the budding Autumn Squill.





This really is a delightful little stroll and beautifully warm for the time of year and I see that we have caper bushes in great abundance. I still haven't tried pickling the leaves as they do in Italy but the little flower buds are delicious on a bit of fish or a pizza. Seems like I'm not the only one who likes capers. A brood of caterpillars. These are Large Whites. Traditionally they are associated with cabbages or other brassicas but although their preferred food plants do indeed tend to be members of the Brassicacae family they have quite a range of host plants from different families.

What a wealth of life we have along the roadside here. I told you that Sklavoi would be interesting. Down on the road we have another of those Huntsman Spiders that we found up in Praesos and sitting on a leaf a little Crab Spider that's recently migrated from a yellow flower and hasn't got round to changing colour yet. Plenty of wasps around the ivy flowers, mainly the common European Wasps which the Americans call Yellowjackets, but also this red and black one which is a Spider Wasp. The adults feed on nectar but their young dine on live spiders. When the female lays an egg she'll seal a spider in with it that she's previously paralysed with her venom. The spider has to be large enough to feed the youngster until he's large enough to fend for himself so the little Crab Spider is probably safe but I'd advise the Huntsman to keep at least one of his eight eyes on the sky above him. And finally... one of those tall plants with small flowers that may be overlooked. Pity really because their flowers are quite charming and the plant, which is a Verbascum or Mullein, contains high levels of Rotenone which we use to treat head lice and scabies. Apparently the US government also uses it to kill fish in rivers but why they should wish to do this is beyond me.

This little track seems to lead back up into the village so that will make a nice circular walk. 

The Extra Bit


So far on the bird table we've had birds, cats and a black rat but this is one animal that I was rather surprised to see, especially as the bird table is only four feet from my bedroom window. It's an endemic Cretan Stone Marten which lives only here and on a few islands in the eastern Mediterranean. It is slightly smaller than the European Stone (or Beech) Marten of which it is a subspecies. It's not totally unusual to find them around human habitation at night but even so, four feet is quite close. I'm taking it as the ultimate proof that I do not snore like a chainsaw (whatever Christina might say).

Photographic Bit

Many of you have asked me what photographic equipment I use so here's a quick rundown on the cameras used for each picture. For details of aperture settings, shutter speeds etc. my pictures will be on Flickr within a few days and that has all the geeky stuff.
