Steve's nature Quiz #19

Last week's #CreteNature blog featured butterflies, dragonflies and hoverflies but which one of these is really a type of fly?


Butterflies have four wings covered in tiny scales and, together with moths, form the order of insects called the Lepidoptera (originally from the Greek meaning scaly wings). Dragonflies also have four wings and, along with damselflies, form the order Odonata (again, originally from the Greek, this time for tooth - as is dentist - referring to their rather formidable mouth parts). Hoverflies, house flies, mosquitoes, midges and a host of others have only two wings and form the order Diptera (from the Greek again; di + ptera meaning two wings). So, whenever you see an insect with only two wings you can be sure that it is a type of fly.

More insect facts, some beautiful flowers and scenery as well as some rare Cretan frogs as the #CreteNature blog wends it's way up to the mountain village of Orino. http://bit.ly/2xRJuLH

To the Village of Orino

Much as it grieves me to leave Nikki's kafenion in Schinokapsala and all those delicious grapes we shall press onwards and upwards to the village of Orino. As we leave the village, heading east, we are at about 1300 feet (400m). Where we are heading is over 2000 feet up in the Thriptis mountains and there is some pretty spectacular scenery upon the way. 

Ah, there's the turning for Mavros Kolimbos and just past here on the left is a little reservoir that's always worth a visit. No birds today, although a pair of ravens have just cronked overhead, but we have a couple of little friends taking a drink at the water's edge. Firstly we have a Keeled Skimmer of the Orthetrum genus. The males of this genus are easy to recognise by their powder blue colour (as opposed to the metallic blue of the much larger Emperors of the Anax genus). The other fellow taking advantage of the algal mat as a landing stage is an Oriental Hornet. This is an east Asian/north African species that appears to be spreading into southern Europe which is not good news for bee keepers as bee hives appear to be one of it's favourite food sources with the bees and their larvae providing protein and the honey providing carbohydrates. On the other hand, they're great pollinators and they are not aggressive (you can get up close and photograph them) although the sting is painful if you happen to sit on one.


As I promised there are lovely views up through the mountains. This is the top of Red Butterfly Gorge, the lower end of which we visited a few years back and just around the bend is Orino itself with its lovely pergolaed village square. And now I should like to introduce you to my wife Christina who will be my nose and ears for our excursions. I've been virtually anosmic for years and I'm pretty near deaf in one ear so I can never pinpoint where anything is. Christina, on the other hand, is virtually blind but between the two of us we can muster up a good set of senses. Anyhow, we'll leave Christina here chatting to a Chaffinch that she assures me is in that tree to my left and go and investigate the top end of the village square.

A nice little pool before the stream dips under the square with some Maidenhair Fern and what looks to be a little patch of Fleabane growing over there on the left. And right over there at the back, a Marmalade Hoverfly has just landed. Not the most spectacular of insects you may think but hoverflies are important biological control agents (this one's larvae eat aphids) as well as being great pollinators. They also migrate long distances and have their own monitoring scheme at Exeter University in the UK as we try to find out more about these little guys and how they help our agricultural efforts (before we destroy them all with insecticides). What I don't see here are any frogs. Maybe we'll have more luck on the other side of the square where the stream re-emerges.


Now, just across the road I see a little alleyway and with luck it will lead us down to the water's edge. Hmm, a lovely old tree and a lot of concrete. I think that we'll have to try and get further down. Tricky but 'do-able'. 

And worth the effort, no less than five Cretan Frogs taking the morning sun. Yes, I did say Cretan Frogs, you'll find them nowhere else in the world and they have a certificate to prove it. To whit: “The species status of Pelophylax cretensis is "confirmed" by short mtDNA sequences and a large number of private allozyme alleles not found in any other water frog.” so the IUCN Red List tells us. Unfortunately it also tells us that it is an endangered species. Like any species endemic to a particular island it is vulnerable to a major disaster such as Santorini blowing its top but in addition habitats like this are declining. Not only is this part of the island getting drier as the climate warms but what water there is gets forced down these ubiquitous plastic pipes for agricultural use downhill. And there's the rub; the human population of Crete needs agriculture to survive economically, the burgeoning world human population needs more and more agriculture to feed itself and the cost is biodiversity. What is particularly galling is the amount of water that gets wasted through leaky pipes and inefficient watering. The technology exists to ameliorate these problems but agricultural water is still cheap on Crete and technology is expensive. Back to simple economics again. The problem will undoubtedly solve itself. As water becomes scarcer it will necessarily become more expensive and better water control will become a viable option. But why wait until then? Better watering practices now will keep the water prices low as well as saving money in the meantime (water is cheap but not free). Meanwhile we'll enjoy the frogs while we still can and in case anyone is thinking “who needs frogs anyway?” guess who eats the cockroaches that invade the greenhouses, to say nothing of mosquito larvae. If you don't want Crete to be insect heaven then save water and save a frog I say.


The Extra Bit

There's a nice little kafenion in the village but unfortunately it is closed today so we'll mosey on back to Schinokapsala. Meanwhile lets see how Christina is getting on with her chaffinch.

What have you got there?”

A sweet lady came and gave me this bag of apples and walnuts to have with my coffee.”

(Cretans are very thoughtful and generous like that).

How lovely. I wonder what would happen if I sat you outside Lidl's with a hat?”

(Time to go I think).


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.

Red Butterfly Gorge



Pick up any brochure for the island of Crete and you will find near the top of the list of tourist attractions Samaria Gorge. And rightly so, at 18km long it is listed as the longest gorge in Europe and it is very beautiful. However Crete, being primarily made of limestone, has many other gorges, equally interesting and much less frequented so if you don’t fancy sharing your Cretan Gorge experience with coach loads of other tourists having the same idea come with me today and I will take you up the Gorge of the Red Butterflies.


We’ll start at the sea end, just west of the village of Koutsouras, where there is a small car park set amongst the pine trees. It is a beautiful February afternoon, there’s not a cloud in the sky and the temperature is a quite balmy 23 degrees centigrade. A pleasant track leads to the start of the gorge and the air is full of the hum of insects and the song of the chaffinch.


Red Admiral Vanessa atalanta
Almost immediately our attention is focused upon a pair of Red Admiral butterflies from which the Gorge takes its name. These magnificent butterflies are resident here and fly all the year round. The species name 'atalanta' derives from a huntress in Greek mythology who, like Eve, had a bit of a problem with apples. Unwilling to agree to her father's decision that she should marry she would only accept a husband who could beat her in a foot race. Losers would be killed. That got rid of a fair few hopefuls until a bit of a cad called Hipponomes came along with three golden apples obtained from Aphrodite, well known love goddess and greengrocer. Every time Atalanta got ahead Hipponomes lobbed an apple to distract her and so won the race and her somewhat reluctant hand in marriage.




Common Darter Sympetrum striolatum
Walking up the track and taking in the smell of the pines the mountain stream is gurgling away to our right and through the narrow belt of trees to our left we get glimpses of the huge escarpment through which the gorge is cut. More butterflies flit across our path as well as the occasional dragonfly. This one is a Common Darter which you can differentiate from similar looking species by the black spots on the penultimate two segments of his abdomen. After twenty minutes of slow meandering we turn sharp left and enter the gorge itself. 




The path is tricky in places but not too strenuous for anyone who is reasonably fit and agile. You don’t need hiking boots and crampons but neither should you attempt it in flip-flops. (I find an old pair of trainers perfectly adequate.) 

Here we lose the smell of the pines and the hum of the insects and enter a silent world where the air smells of solid rock. As we thread our way through narrow defiles the immensity of the walls to either side makes us feel as though we are setting out on a quest in some obscure chapter of Tolkein’s Lord of the Rings. One half expects to encounter goblins and dragons in some of the darker recesses and caves that punctuate the massive stone sides of the canyon.




Green serpentine rocks
To add to the illusion the ground beneath our feet is littered with strange green rocks. These are serpentine rocks named, I believe, by the Romans who likened their colour to serpents. They are formed when igneous rocks are pushed up from the Earth’s mantle below the crust and changed by the addition of water and a reduction in heat and pressure. This destablises the minerals within the rock in a process known as, not unreasonably, Serpentinization. (Thank you Geoman at Oregon University for guiding me through that one).


Cretan Sowbread Cyclamen creticum
But dragons and goblins aside here’s a flower I came specifically to see. Locally I’ve only found it growing here in this spot and only in the month of February although I am told that it is quite abundant in other parts of the island between March and May. It’s a Cretan/Karpathian endemic Cyclamen (i.e. it only grows on Crete and the nearby island of Karpathos). It is a shade loving plant which has either pure white flowers or, like these, white flushed with pink. 

Many flowers attract particular species of moths as food plants for their caterpillars. The Cretan Sowbread, to give it its common English name, is the host plant for a Noctuid moth called The Gothic which seems very apt for this dark and eerie place.






And now, having assured myself that they are still thriving here, I am going to turn back. You carry on if you wish. The way is well marked, just bear right at the fork in the track (no I didn’t bring it with me for a cheap photographic joke – honest) and in another couple of hours you’ll reach the little village of Orino where you can get a much needed drink and a bite to eat.

 

For those who don’t fancy the trek let’s see if we can find a few more butterflies on the way back through the pines.




Speckled Wood Pararge aegerea
Plenty of Small Whites and I’ve counted at least half a dozen more Red Admirals but here, flitting through the dappled shade, is another member of the Nymphalidae family; the Speckled Wood. 

This family of butterflies is recognisable by their forelegs which are rather small in most species and sometimes give the misleading impression that the butterfly has only four legs.

No time again to talk about the other things that we've encountered along the way such as the ants and the different species of Anemone but there's always more going on on our  facebook page: Steve's Naturalists Group 

 
Until next week – good hunting and I'll leave you with a couple more pictures of Red Butterfly Gorge:
