Reasonably common across France, and commonly found at altitude, often in good numbers. The upperside can be differentiated from the High Brown Fritillary (A. adippe) by the indicators described on the adippe page.

 

The upperside can be differentiated from the Niobe Fritillary (A. niobe) by the rather heavier submarginal marks on both upf and unh of aglaja compared to niobe.

The undersides of each of the three species are quite different and easily distinguishable.

 

In some textbooks aglaja is spelt aglaia.

18040 M

a male puddling, the forewings held back in a pose that seems normal for aglaja when puddling. The orange seems rather dull compared to others on this page, but it is not clear whether this is natural or just the result of wear.

1120
26482 M a very fresh male. 1400
44156 M a male puddling, almost completely fresh and a beautiful deep orange colour, even with orange-ish fringes. 1600
7827 M

a male, based on the lighter markings, the albeit quite light sex brands on v2 and v3, and the just-visible body. Not 100% certain, though.

2100
44579 F a female, slightly unusual in that the upf post-discal spots are rather heavy. 1550
27084 F a female, slightly suffused. 2020
22597 F

a female as indicated by the heavier markings and confirmed by the absence of sex brands.

05_19-07 F

an old photograph of a very heavily marked and suffused female. It actually looked like this in real life. I have seen females like this on a few subsequent occasions.

 
18301 M a male puddling. 1120
33160 M a male, probably immediately after emergence. It is unusual in that much of the area surrounding the silver marks is brown rather than green, although it is rather greener in the lower regions of the hindwing. 1100
30842 M a male puddling. 1240
