Possible origination of wing patterns with more than six fasciae. a Ancestral wing patterns are comprised of dark bands straddling alternating veins, as in Micropterix, Sabatinca doroxena, etc. b Derived wing patterns include spots that straddle all veins at the costa, as in Sabatinca demissa. c Each spot along the costa could extend into a band that reaches the dorsum
