Provincial Status:
CDC rank: S4
Widespread south of 52° N; not known
from northern British Columbia, but records from the Yukon and Northwest
territories indicate that this species is probably sparsely distributed
throughout the northern half of the province. Columbia-Kootenay
Distribution
Known from five localities in the southern half of the region, but
is undoubtedly more widespread.
Global Distribution
Yukon east to Manitoba, south to Missouri, Oklahoma, Colorado and
California (Bick and Mauffray 2000). Faunal element: Western (see
Appendix 2).
Biological information
S. madidum develops in a variety of still-water habitats,
including sedge fens and grassland ponds and marshes; these sites
are often ephemeral. Cannings (1980b, 1981) described the
larva and the ecological preferences of S. madidum on the
Chilcotin Plateau. The flight period in British Columbia ranges
from 26 May to 9 September (Cannings and Stuart 1977), but the known
Kootenay dates are much more restricted -- 19 July to 29 August.
