Pearl-bordered and Small Pearl-bordered Fritillaries
COMPARISON PHOTOGRAPHS
 
Pearl-bordered Fritillary Clossiana euphrosyne, male. Compare the pattern of black markings in the median area of the hindwings with the Small Pearl-bordered Fritillary below :
 
Small Pearl-bordered Fritillary Clossiana selene, male. The submarginal markings take the form of contiguous black chevrons - compare with the crescents of euphrosyne ( top picture ).
 
Pearl-bordered Fritillary has reddish chevrons on the inner edge of the submarginal silver spots.
 
Small Pearl-bordered Fritillary has prominent black chevrons, veins and post-median spots. It also has additional silver spots in the median area of the underside hindwings.
 
Behavioural differences :
 
Pearl-bordered Fritillary nectars almost exclusively at bugle, but sometimes visits dandelions and hawthorn blossom.
 
Small Pearl-bordered Fritillary will nectar at bugle if the butterflies emerge very early, but normally prefers to visit ragged robin, thistles and wood spurge.
