Common Blue (Polyommatus icarus) or Brown Argus (Plebeius agestis) ? Most of you suggested me the Common Blue, but finally, Alina (Alutka) posted a useful workshop with the comparison between the two species. Alina was right: it is a Brown Argus. Thanks a lot!

Plebeius agestis (Denis & Schiffermüller, 1775)
Family : Lycaenidae

Unlike most other "blues", the Brown Argus has no blue scales on its upperside, being primarily brown in colour as its name suggests, although it does exhibit a blue sheen when at certain angles to the light. Both sexes have beautiful orange markings on the upperside of both forewings and hindwings.
This species occurs in small, compact colonies, and is not a great wanderer, only travelling a couple of hundred metres, at most, from where it emerged.

Like its close relative, the Common Blue, this species will roost communally on grass stems at night. In fact, the two species are sometimes found roosting together.
The Brown Argus and Common Blue can be differentiated from their undersides, since the Brown Argus lacks a spot on the underside of the forewing that is present in the Common Blue.
The Brown Argus and female Common Blue can be difficult to tell apart from their uppersides. However, the Brown Argus is completely lacking in blue scales, but may have a blue sheen. The highly-variable female Common Blue, on the other hand, always has some blue scaling, especially close to the body. (UK Butterflies)

The butterfly's traditional habitats are chalk and limestone grassland, but it also occurs in a range of other habitats with disturbed soils, including: coastal grassland and dunes, woodland clearings, heathland, disused railway lines, road verges, and more recently set-aside fields. Sheltered sites or slopes facing south or west are preferred.

It is widespread and common across Europe as far north as Denmark and southern Sweden, across to the Middle East and Siberia, and also in North Africa. It has declined in a few western European countries. (Butterfly Conservation)

In Belgium, it is a rather rare species throughout Belgium. Vulnerable.
The adults fly in two generations a year: from mid May till mid June, and from early July till the end of September. (Lepidoptera of Belgium)

Witaj Catherine,
zrobiłaś zdjęcie Plebeius agestis ( Brown Argus ).

Wonderful capture of this common blue(I think).
Sharp, colours and POV is excellent.
Flower give a good note to this capture.

Hi Catherine,

Beautiful macro shot of the Common Blue!
To my knowledge, it is female Common Blue. Today, I have also contributed the same subject :)
The sharpness and POV are great in your shot, certainly better than I had. The colors are perfect and the colors of the butterfly are giving great contrast to teh blurred BG.
Great composition.

Thanks for posting.

Hello Catherine,
A very fine close macro of a Aricia agestis taken from a fine POV to show the closed wings with almost total sharpness against a pleasing OOF BG. Nicely composed on the marjoram flower too.
Thanks and have a good weekend,

Ciao Catherine, splendid composition with lovely little butterfly and beautiful flower, fantastic colors, good details and excellent sharpness, perfect focus and wonderful blurry BG, very well done, ciao Silvio
