Variation

See dedicated page: Variation


Adults are sexually dimorphic.[1]

The shape and color of the wings change at the beginning of the migration and appear redder and more elongated than later migrants.[2] Wings size and shape differ between migratory and non-migratory monarchs. Monarchs from eastern North America have larger and more angular forewings than those in the western population.[3]

Female Male Description

Adult male.

Males are slightly larger than females[3][4] and have a black patch or spot of androconial scales on each hindwing. The male's black wing veins are lighter and narrower than those of females.[1]

D. p. plexippus form nivosus chrysalis.
 
D. p. plexippus form nivosus adult.

Known informally as the "white monarch", but called nivosus by lepidopterists. It is grayish white in all areas of its wings that are normally orange and is only about 1% or less of all monarchs, but populations as high as 10% exist on Oahu in Hawaii. Also observed in Australia, New Zealand, Indonesia and the United States.[5]
