examination of the markings is required when identifying most European fritillaries,
including the Marbled Fritillary Brenthis daphne. This Butterfly
Conservation European Butterflies reference: http://www.european-butterflies.org.uk/downloads/EURO%20FRITS%20GUIDE.pdf offers excellent guidance, and it
should enable most European fritillaries to be identified from clear
photographs – if the appropriate features can be seen. It is easy to get them
wrong as the markings may be almost identical, albeit variable, for closely
related species, and since he discovered it, the author has been carefully cross-checking
old photographs for misidentifications – including the images shown above – and
by doing so he has identified a couple of species that he didn’t know that he
had photographed! There have been some recent reclassifications in the light of
DNA sequence analysis too, sometimes of insects that would have been correctly
identified according to the contemporary references. There are many beautifully
illustrated books available for students of for butterflies but looking at a high-resolution
PDF enlarged on a computer screen offers distinct advantages when making any direct
comparisons with the details in photographs. The upperside
illustrations on this page show the absence of sex-brands on the forewings of the
male Marbled Fritillary (note also, the bright orange ground colour) and these
photographs and the first picture of the underside (of a different individual) are
good matches for the illustrations highlighting the significant differences between
this butterfly and its close relatives in the on-line reference material
referred to above. The photographs were taken in Switzerland.
