General Description
fourni par University of Alberta Museums
Superficially similar to the other checkered skippers, but this little skipper (wingspan 16 - 22 mm) inhabits only prairie habitat, along with the Common Checkered Skipper (P. communis). In addition to its smaller size, the white markings of scriptura are much smaller than those of communis.

Life Cycle
fourni par University of Alberta Museums
No data relevant to Alberta are available, and the early stages are undescribed. This species is likely double-brooded in Alberta, since there are two flights (May and July to mid August) in the northern U.S. (Layberry et al. 1998). The only other Canadian record, from Saskatchewan, is from May 19 (Layberry et al. 1998). This species is easily overlooked because of its small size, light colouration and fast flight (McCabe & Post 1977).

Trophic Strategy
fourni par University of Alberta Museums
The larval hostplant in the US is Alkali Mallow (Sida hederacea) (Layberry et al. 1998). Other herbaceous mallows such as Scarlet Mallow (Sphaeralcea coccina) are likely hosts in Alberta, since Sida spp. are not known to occur here (Moss 1992).
