A very common, especially in the south, and extremely variable, fritillary. The male is usually a strong shade of orange-red but can be almost brick red. The female is paler and often suffused greyish and more heavily marked. The female is especially variable.

 

It could only be confused with the Lesser Spotted Fritillary (M. trivia) but not in France, as the trivia distribution is principally the Iberian peninsula and the Balkans.

Most, if not all, of these shots are of the subspecies meridionalis, which is the normal form in southern Europe, characterised in the male by the fiery red colour and strongly crescented black uph submarginal spots which are not attached to the marginal band, and generally cleaner feel. The female can occur in darker forms especially at altitude, 33074 being a rather extreme example.

alt. m
18267 M

a heavily marked male, probably intermediate between the nominate form and meridionalis.

1120
6554 M

a beautifully marked male of the subspecies meridionalis, the strong black borders contrasting well with the bright red-orange of this fresh specimen.

220
15437 M

another male of the subspecies meridionalis.

35
35869 M a darker, less orange male from a higher altitude. 1200
45609 M a particularly dark male, especially at the borders, probably an altitude effect, 45689 being from the highest altitude of those on this page. The discal mark in upf s1 is also notably large and dark. 1830
36457 F a rather orange and lightly marked female from the Rhône. 180
13733 F

a very typical female, very similar to 9393.

750
9393 F

a female, naturally and unusually pale, not through wear. This is reflected (literally!) in the underside 9394.

780
18197 F

the dark form of the female, with only a trace of orange.

1200
33074 F a particularly dark female, perhaps the darkest I have ever seen. It did appear to be perfectly fresh, though. 1000
19955 M

a beautifully marked male underside, probably just emerged. Incredible subtlety of design.

10
2890 M

a male underside, a beautiful combination of cream and orange markings, with strong submarginal black crescents matching the upperside pattern.

60
44481 M a male underside, very pale and white, the orange marks being greatly reduced and almost vestigial in the discal region. 1550
9394 F

the underside of 9393, as delicately marked as the upperside. Fabulous light orange markings on a pale cream base.

780
31932 LARVA a larva, in its final stages. 20
