General Description

By Nora Bryan

The Atlantis Fritillary is on the wing in July and August across Alberta. It prefers forested areas over the prairies and can be found nectaring at flowers.

The large Atlantis fritillary has a wingspan of 60 to 70 mm (2 ? to 2 in.). The upper wing surfaces have the characteristic orange and black markings that are typical of fritillaries, overall often darker than other fritillaries. The forewings and often the hind wings have a solid black border. The underside of the hindwing sports many silvery spots against a purplish brown background. There is a yellow band between the outer row of spots and the inner ones but it is not as wide and clear as that of the Great Spangled Fritillary.

The velvety black caterpillars sport grey or brown stripes with orange spines, and like most of their kin munch at night on violet leaves.
