As high winds continue to affect S. Sweden I had to look for an image in my archives. The standard of my images is now reduced but I thought this one of the Mazarine Blue, Polyommatus (Cyaniris) semiargus was worth posting mainly because my previous posting of this species shows the underside.

This reminds one that many butterflies are best identified by looking at the underside. The Mazarine Blue is one of the European species that lacks any orange spots on the underside. This fact helps to reduce the number of blue butterflies to differentiate it from.

Looking at the upper surface one can see that the purplish blue of the wings changes to a light powdery blue near the body, while the margins of the wings are bordered by black and white bands of about the same width. On noticing this in fresh males it easy to ID it from other blues that fly in the same habitat at the same time. A look at the underside can then confirm the ID.

The Mazarine Blue is widespread and locally common in most of Sweden and Europe, though it is rarer in the west and absent from the UK. It thrives in flowery meadows, a declining habitat that has led to a decline in this species.
The larval host plants are various species of Leguminous plants, mostly clovers like Trifolium pratense.

This was taken with the camera hand-held at a distance of about two meters. After moderate cropping and size reduction the image was selectively sharpened and some noise remains.

Hej Ivan,
a very fine picture and it was worth posting, it's a really
summer reminder. Lovely colours and nice lighting.
Well composed with good DOF and fine details.
Beautiful work.

Soligt men blåsigt häruppe.
Har fortfarande en släng av influensan kvar, hostig och lite febrig så det blir till att hålla sig inne idag också ;-((
Micke och jag hade planer på att åka upp till Lavskrikan idag
men det blir skjutet på framtiden.


Another of your super-fine tele-macros from your seemingly bottomless archive Ivan, an egoistical thinking maybe my friend but I become almost happy when your weather conditions worsen, for then I know that we will receive something nice and sunny from your archives! Thank you for sharing this sweet blue with us my friend.

Hi Ivan

Sounds like your having a lousy winter, well we've a very wet and cool summer this year. I've only ybeen out a few times since I got back from overseas.
Anyway this is a great one from the archives. I really like blues and the northern hemisphere one seem to have a strong hue and better define veins than the ones we get here. I think the sharpness is good and its on a prety good background.


Ciao Ivan,
una splendida immagine di C. semiargus.
In effetti, l'identificazione è più facile osservando il lato inferiore.
Tuttavia il colore blu violaceo scuro con bordo nero più o meno ampio e le tracce di nero lungo le nervature è caratteristico di questa specie e permette di distinguerla, con un certo allenamento, anche osservandola da sopra.
Complimenti per la bella composizione.

Hi friend Ivan,
A perfect shot of this beautiful butterfly!
Good exposure and focus achieved the perfect sharpness, nice colour and details.
TFS and Cheers,

Splendid photo Ivan!
You've frozen this beautiful butterfly in time with expert skill.
Composition, POV, DOF, focusing, exposure, lighting, sharpness, clarity, colours... all are spot-on.
Exceptionally well done.

Hi Ivan,
a very clear, precise focus has given this an almost 3D feel. The DOF adds to this effect and composition is flawless. A great piece of work, very well done.

Hello Ivan, well done on that great butterfly, the sharp details, the great composition and the very good exposure made this shot a great one ! Thanks!



An excellent shot that is well composed, with good POV, DOF, BG, Sharpness and detail.

You have shown us the blues very frequently and this one is yet another great image, Ivan.
Superb colours and a fantastic blurred BG.
TFS and regards.

Hi Ivan
Beautiful shot. Great vivid green, blue and yellow. Perfect sharpness, great OOF background and good composition with butterfly on the left
I like it very much

You certainly know your butterflies Ivan. Add to that the sharp image and the very pleasant relaxing colour of this creature and you have a very pretty picture....I do believe I will add this to my blue theme. It gives a sense fo what I feel and how comfortable with this particular shade.

Hi Ivan,
The blue color of this Blue is so fresh. Sharp focus and nice color clarity. Great pov and composition. TFS,

Hi Ivan,
Outstanding shot of this beautiful blue butterfly with immaculate sharpness and colours. Great lighting and a precise DOF isolates it from the BG. Wonderful pose captured and I like this diagonal composition. Kudos.

Hi Ivan,

Lovely colours and the butterfly have much details also good of sharpness.
Good exposure and dof can right by his wings a little more.

Como en muchas de tus tomas, sencillez y practicidad, con unos colores que se asimilan mucho a la realidad.

Hello Ivan,
the focus on the body and the left wings and the achieved sharpness is pretty good (you have not to excuse for lower quality)!
The particular blue of the species is nicely reproduced.
Furthermore, the picture is well composed.
Best wishes, Peter

Hi Ivan

Sorry to hear that weather up there is not on your side, my friend :(
Here it is still mostly sunny but from what i've heard, it will change to worse in the upcoming days...

Anyway, this is a very beautiful shot from you archives! You really do have an impressive collection of these :)
I love the details that you manage to capture on this little fellow and the very nicely visible hairs. The DOF is almost perfect here - it creates an amazing bokeh in the BG and it keeps the butterfly in very good focus...all but one wing tip :)
But even with that, i can appreciate this beautiful shot because of its charming colors, great composition and - as usual - very good note.

Bravo and TFS

Hello Ivan,
A very beautiful pose of the butterfly!
Best DOF to achieve the perfect sharpness, beautiful colouration and details in the shot
as good as ever from any of your posting
have a wonderful weekend

Superb shot Ivan, very beautiful. This butterfly is unknown to me and it is such a nice one with the blue fur. To my point of view, the standard of your pictures is absolutely not reduced as it is always so well photographed, with perfect light and sharpness, beautiful background. Lovely,


merhaba Ivan,
a perfect closed up one of your Blues with excellent sharp focus, wonderful POV/DOF and composition. Coloration superb with mainly green, yellow and blue nicely contrasting. Great notes always.
Many thanks for sharing and your kind e-mail.
Have a wonderful day

Good morning Ivan, thank you so much for your most comprehensive ID notes. I shall keep this photo in my favourites, as a reference. You have said, "The standard of my images is now reduced ...", if this is so, I can only express admiration. Beautiful clear image, with very fine markings on the wings.
