Orthetrum coerulescens (Karinalı Yusufcuk) [Eng. ‘Keeled Skimmer’]

Today, I am presenting a “love wheel” position of a pair of dragonfly species which I captured during my Black Sea Region trip in Çayeli (Rize province) in 2009.

TFL and Have a nice weekend!
Cheers,

*****************************


Karinalı Yusufçuk, benzer olan Güney Yusufçuğu O. brunneum ve daha da güneydeki diğer bazı benzer türlerle birlikte, Akdeniz havzasında akarsularda yaygın ve küçük Orthetrum türlerinden biridir. 36-45 mm toplam uzunluk (Abdomen uzunluğu: 23-38 mm, açılmış arka kanat genişliği 28-33 mm) ile yaklaşık Sympetrum striolatum boyutlarındadır. Pek çok alanda, ergin erkekleri O. brunneum hariç, tamamı pudramsı abdomeni ve sarı pterostigması ile diğer bütün libellulidlerden ayrılır. Bununla birlikte, genç erkekleri ve dişileri çoğu kez Sympetrum cinsine dahil türler ile karıştırılır.

O. coerulescens oldukça küçük boyutu, dereceli şekilde giderek incelen abdomeni ve büyük (yaklaşık 4 mm uzunluğunda) pterostigmaları ile karakterize olur. Benzer türlerden farklı olarak, erkeklerinde toraksda çok az pudramsılık gelişir ve kahverengi bir yüze sahiptir. Bu nedenle de tamamen mavi olmaktan çok, iki renkli görünürler. Thoraksın ön tarafında, çoğunlukla iki soluk şerit bulunur, ancak yanlar tekdüze renktedir. İki alttürü bilinir. Güney alttürü ssp. anceps, önceden O. ramburii olarak da anılmış ayrı bir tür olarak kabul edilmiştir. Ancak bu durum büyük alanlardaki ara durumda bulunan bireyleri açıklamaktan uzaktır. Tipik alttür ssp. coerulescens erkeklerine yandan bakıldığında, abdomen eksenine neredeyse dikey duran bir ön laminaya (yapraksı ince tabaka) sahip oldukları görülür. Apeksi şişkince ve yuvarlağımsıdır. Tipik ssp. anceps ise daha sivri ve üçgenimsi bir ön laminaya sahiptir ve geriye doğru yönelimlidir. Güneyli erkekler (haliyle ssp. anceps’i içerecek şekilde) daha koyu ve daha çok pudramsı olmaya meyillidirler ve tamamen mavi görünebilirler.

Normal olarak bitkiler üzerine, çok nadir olarak da yere konar. Uçuşu oldukça ürkek ve sık olarak bulunduğu yöreden fazla uzaklaşmaz, çok sık konar. Zayıf uçuşlu gibi görünmesine karşın, sudan oldukça uzun meseafeler uçabilir. Bir yere tutunduğunda kanatları öne doğru tutulur.

Karinalı Yusufcuk Akdeniz havzasında yaygın olmakla beraber, genel olarak orta ve kuzey Avrupa’da yerel şekilde bulunur. Tipik alttürü, ssp. anceps K Afrika, Asya (K Hindistan’a kadar), Sardunya ve güney Balkanlar’da dağılış gösterir. Ara formlar İber yarımadası, Sicilya ve GD Avrupa’nın büyük bir kısmında görülürken, tipik alttürlerinden, ssp. coerulescens Rusya’ya giriş yapacak şekilde marjinal dağılışlıdır. Nisan’dan Kasım’a, ama en bol olarak da Haziran’dan Ağustos’a kadar uçuş halindedir.

*****************************

Keeled Skimmer is a common, small Orthetrum of flowing water around the Mediterranean found with the similar O. brunneum (Southern Skimmer) and several other look-alikes in the far south. It is about the size of Sympetrum striolatum with a total length of 36-45mm (Abdomen length: 23-38mm, Hind wing spans: 28-33mm). In most areas, the mature male is separated from all libellulids, except O. brunneum, by the all-pruinose abdomen and yellow pterostigma, but young males and females are often confused with Sympetrum.

O. coerulescens is characterised by its rather small size, fairly slender tapering abdomen and large pterostigmas (around 4mm long). Unlike similar species, the mature male develops little pruinosity on the thorax, and has a brown face. It thus appears two-coloured, rather than all-blue. Usually, two pale stripes on the front of the thorax are visible, but the sides are a uniform colour. Two subspecies are recognized. The southern ssp. anceps has been considered a good species, formerly often called O. ramburii, but this is unjustified as intermediate individuals occur in large areas. Seen from the side, typical ssp. coerulescens males have the anterior lamina standing nearly perpendicular to the abdominal axis. Its apex is inflated and rounded. Typical ssp. anceps has a more pointed and triangular anterior lamina, which is directed more backwards. Southern males (thus including ssp anceps) tend to be more densely and extensively pruinose and may seem totally blue.
It is normally sits on vegetation, seldom on the ground. Its flight is quite skittish, with frequent hovering, and it lands often. It can fly quite a distance from water, despite its seemingly weak flight. When it perches, the wings are held forward.

Keeled Skimmer is common around the Mediterranean, but generally local in central and northern Europe. Typical ssp. anceps is found in N Africa, Asia (to N India), Sardinia and the S Balkans. Intermediate forms predominante in Iberia, Sicily and large parts of SE Europe. Elsewhere, typical ssp. coerulescens is found, marginally entering Russia. It flights from April to November, most abundant from June to August.

A Note On Mating and Breeding Behaviours of D-flies:

In breeding period, the first step is the capture of a female by a male. Males typically grab females by the thorax in flight with their legs, then shift them around so the male's terminal abdominal appendages are holding the female by the head in dragonflies or behind the head (the prothorax) in damselflies. Both insects are facing the same direction, the female behind and below the male. The pair, said to be "in tandem", will continue to fly this way until actual fertilization takes place. Many species will fly to a perch for the next step, and others will continue in flight.

In order to transfer the sperm from the male to the female, whether perched or in flight, the female will curl the tip of her abdomen up to meet the accessory genitalia of the male. The pair is now in “wheel position, and females often reach up with their legs to grasp the male's abdomen. In the more flexible damselflies, the wheel position may be likened to the shape of a heart.

After several mating sessions many males bear marks on their abdomen near segment 7, where the females have been holding on. Several important steps are now taken. Using a set of paddle-like structures unique to odonates and some spiders, the male literally "scoops" away sperm left over from previous matings by this female. After that, the male deposits his sperm into the female. This process can take from just a minute or so up to an hour or more in some species. In perched species, observers can see visible pumping as this process is concluded. The female receives enough sperm in anyone mating session to fertilize all her eggs during her adult life, but if she gets captured by another male the whole process will occur again. During both the tandem and wheel positions other males often try to snare the female for their own breeding attempt.

Merhaba hocam,

Bu mavimsi yusufçuklarımızı kalbi duygular içinde:) görüntülemişsiniz. Aşk seli serisini bitirdiniz herhalde, başlık farklı çıkmış. Gitmediğiniz vatan köşesi kalmamış. Oraya kadar gitmişken koca başlı su yılanımızı (Hemşin yılanı) da çekseydiniz:))
Selam ve sevgilerimle
Ömer.

This one looks like he should be ARRESTED:-) GREAT shot of the blues..I love the blue ones...fine saturation. Good show and a tip of my hat to you kind sir.

Hello Bayram,
Great capture of this mating pair of dragonflies. Wonderful exposure allowing us to see the light powery blue colors and nice detail. I have to be honest and say their positions sure don't look to be very comfortable, but then I'm not a dragonfly. Great presentation as always!
Ron

Bayram..ne kadar guzel bir ask sahnesi:) gercektende tekerlek gibi olmuslar..ellerine saglik canim kardesim.. iyi bir gun diliyorum.. hepimizden selamlar.

Recreaste de manera insólita a esta pareja de libélulas poco vistas por aquí.
Supiste "introducirte" e "introducirnos" en la escena, lo que habla también
de la habilidad del fotógrafo.

That's what I call passion....but what I love the most here is the marvellous color-combination blue and green, one of my favourites. How beautiful also the attitude of the female! Excellent focus on her eyes and legs.
Great shot!
Have a nice weekend
