Toujours aussi beau et photogénique ce petit Argus bleu, mais le plus extraordinaire c'est son cycle de vie.!
Après avoir pendu ses oeufs et l'éclosion de ces derniers, les larves se nourrissent de la plante hôte puis se laissent tomber par terre sur le chemin des fourmis, qui les prennent pour des leurs, les amènent dans la fourmilière et les nourrissent copieusement.!
Mais le jour J quand le papillon sort de sa chrysalide et doit sortir de la fourmilière à l'air libre, il a intérêt à faire vite avant que les fourmis ne s'aperçoivent de la supercherie.!
Sinon il finira au menu du jour.
Always so beautiful and photogenic this little blue Argus, but the most extraordinary is its life cycle!
After hanging eggs and hatching, the larvae feed on the host plant and then fall to the ground on the path of ants, which take them for their own, bring them into the anthill and feed them copiously. !
But on D-day when the butterfly comes out of its chrysalis and has to get out of the anthill in the open air, it is better to do it quickly before the ants can see the trickery!
Otherwise it will end at the menu of the day.

I know I've posted a shot of this before , because this 1956 model is one of the nicer cameras ever made at the Argus Camera company, pride of my hometown. The styling does seem a little unsettled, with the body harkening back to the 1940s and the lens looking forward towards the 1960s.
A couple of additional details, though:
I've learned that the formula for the 4-element Tessar-type lens was computed using "MIDAC," one of the earliest digital computers ever built in the midwest, and operated by the University of Michigan (this is reported on pg. 16 and 18 of the Sept. 1956 Popular Photography).
The designation "high-index, rare-earth crown glass" can be a bit of a red flag, namely that it might contain radioactive thorium in the melt. I don't have any information about that, but closely examining the Cintagon it does seem to show a trace of "browning" of the kind you sometimes see in radioactive glass.
It can be unclear whether you should style this camera's model designation as C44 or C-Forty-Four (or all in lowercase) or C-44. But our local library has scanned many issues of the Argus in-house newsletter and put them online; and these seem pretty consistent in printing it as "C-44" (with the hyphen).
Although the sound is a little funky, you might enjoy this 27-minute industrial film about how Argus cameras were made.
Autre nom pour ce papillon est l'Azuré des anthyllides
Nom binominal : Polyomatus semiargus
Heureusement, ne paraît pas menacé de disparition en Suisse.
A tiny (approx 25-30mm wingspan) butterfly of the same family as the blue butterflies.
Unlike most other "blues", the Brown Argus has no blue scales on its upperside, both sexes being primarily brown in colour as its common name suggests, although the butterfly does exhibit a blue sheen when at certain angles to the light. Both sexes have beautiful orange spots 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.
Such a tiny butterfly the Brown Argus delighted to find this one today at my local reserve.
Many thanks to you ALL for the views, faves and comments you make on my shots it is very appreciated.
Another brown argus from this summer. Almost all of the photos I had taken until recently were brown argus, I'm not sure what happened to the common blues early on but they have started appearing now
The Argus C3 was a low-priced 35mm rangefinder camera mass-produced from 1939 to 1966 by Argus in Ann Arbor, Michigan, United States. The camera sold about 2 million units, making it one of the most popular cameras in history. Due to its shape, size, and weight, it is commonly referred to as "The Brick" by photographers (in Japan its nickname translates as "The Lunchbox"). The most famous 20th-century photographer who used it was Tony Vaccaro, who employed this model during World War II taking most of his images with an Argus C3, even developing the images in soldiers' helmets. This camera had a 50mm/3.5 coated screw-mounted Cintar lens.
Status: works. Focus wheel is very stiff.
A new-to-me Argus C-3 rangefinder. From the serial number and its location, this camera appears to date from 1945-46. Everything on it seems to work, but we will see.

One clamp lamp w/ daylight-balanced CFL camera left, gloss white background to rear. Sitting on glass over black craft paper.
A very low end 127 roll film camera. It has a self cocking shutter, meniscus lens, and 2 aperture settings: f11 & f16. It also has a bulb setting on the shutter for long exposures. These originally came with a battery powered flash that used AG-1 flashbulbs.
I think it looks cool though.
