Small Pearl-bordered Fritillary

Boloria selenePhotoWingspan: Male 41mm, female 44mm 

To separate the Small Pearl from its larger cousin you need to look at the underside of the hindwing. The six or seven whitish silver pearls at the outer edge of the wing are bordered by black chevrons, whereas those on the Pearl are orange-brown. More noticeable are the more numerous (up to six) silver patches on the Small Pearl (there are only two on the Pearl).
