Crepusculans from Latin, of dusk, active at sundown or before daybreak, and in the half light of moon-lit nights. Remarks. The Zululand topotypical population of crepusculans is seasonally (May to late August/September) greatly outnumbered by wintering examples of nominate pectoralis from further south. McLachlan & Liversidge (1970) record that eggs of what they refer to as C. p. fervidus (but probably — C. p. crepusculans) are smaller than those of nominate C. pectoralis: x (n=6), versus x and x 20 (n=2) mm.
