|scientific name Euptoieta claudia |
common name Variegated Fritillary
Prairie and alpine meadows, pastures, and roadsides; migratory and ubiquitous.
Migrants arrive in June, and their offspring emerge mid July to mid August, occasionally into Oct.
Unlike the Speyeria fritillaries, the underside lacks all silvery markings. The elongate forewing shape is also unique. There are no described subspecies.
The pale green or cream-coloured eggs are laid singly (Scott 1986). Grown larvae are reddish with black and white bands and black spines (Layberry et al. 1998). The strikingly ornate pupa is shiny greenish-cream with small black dots and gold tubercles (Scott 1986).
Not of concern.
Scott (1986) lists many larval hosts in 10 different families, some of which are strictly tropical. Potential hosts that occur in Alberta include violets (Viola), plantain (Plantago), flax (Linum) and stonecrop (Sedum). Gary Anweiler observed a female ovipositing on a tiny, unfurling violet leaf on a campground gravel pad near Trochu.
The distribution is centered on central America, ranging south to Argentina and occasionally migrating as far north as southern Canada. A single record from Churchill, Manitoba (Scott 1986, Layberry et al. 1998).
