Abstract
Thirteen Speyeria nokomis apacheana (Edwards) (Nymphalidae) population s from the western Great Basin were assayed for isozyme variability us ing starch-gel electrophoresis. Eight of the 25 presumptive isozyme lo ci analyzed were found to be polymorphic. Collections made in 1991 and 1992 allowed for between-year comparisons of heterozygosity and the e stimation of effective population size for five of the sampled populat ions. Speyeria nokomis apacheana populations exhibit lower mean hetero zygosity levels than other nymphalids. This may be attributed to genet ic drift in apparently isolated populations with small effective sizes .
