Baltimore Checkerspot (Euphydryas phaeton)

Great Spangled Fritillary (Speyeria cybele)

The Great Spangled Fritillary is the most common Fritillary on southern Ontario. As with many species of butterflies and wildlife in nature, you sometimes need to get different views of the individual before you can make a positive identification. Jim Fairchild was able to get a couple of good pictures, which when combined, allows you to identify this butterfly as a Great Spangled Fritillary, as opposed to any other Fritillary. The most compelling field mark of the GS Fritillary is the broad ligher coloured postmedian band on the underside of the hindwing.

Silver-bordered Fritillary (Boloria selene)

The Silver-bordered Fritillary is a less common species of Fritillary in Ontario. It is smaller, about the size of a Pearl Crescent. The field marks to look for when trying to identify this species are the diagnostic median and marginal silver-coloured spots on the underside of both wings. Also in the HW cell area is an egg shaped silver spot above a dark area with an eyespot. The Bog Fritiallary is similar, but is white spots in the postmedian band, whereas the Silver-bordered Fritillary had black spots. The Silver-bordered Fritillary's habitiat is bog, wet meadows, wet prairies, marshes, as well as open fields in mid to late summer.
