|scientific name Euphydryas anicia |
common name Anicia Checkerspot
Montane, subalpine and alpine meadows
One yearly flight peaking in June to July, depending on elevation and snowpack.
The upperside is checkered in orange-red and cream with black lines and spot-rows; the underside has a similar pattern but with very little black. Anicia is similar to Edith's Checkerspot (E. editha), but is larger with brighter markings, particularly on the hindwing underside. The forewing outer margin has a slight point below the apex in anicia, but is evenly rounded in editha. Edith's occurs only in the Cypress Hills and well above treeline in the Rockies. Specimens of uncertain identity can be determined using genitalic differences (eg. see Guppy & Shepard 2001).
No life history data are available for Alberta populations. A large number names have been applied to this group, and some authors consider this complex to be one, extremely variable species, E. chalcedona (Layberry et al. 1998).
Not of concern.
Host plant unrecorded in AB; likely beard tongue (Penstemon spp.) and / or paintbrush (Castilleja spp.) here, as these are common hosts in the western US (Scott 1986).
Alaska to northern Mexico, east tot the Cypress Hills and Nebraska (Scott 1986).
