Mariposas is a board game by Wingspan designer Elizabeth Hargrave (see "Rolling for Initiative--The 'Wingspan' Thing") about the migration of monarch butterflies across the eastern North American continent. This game progresses through three seasons where the players' butterflies attempt to travel north in spring, disperse to different regions in the summer months, and then, migrate south in fall. Through the seasons players collect butterflies as they mind the movement of their family of butterflies. Each season has a scoring round, and the game ends in fall where the player with the most victory points worth of butterflies wins the game.
Elizabeth Hargrave has been an in-demand designer as of late, and she also sold a design to Pandasaurus Games (see "Exclusive: Pandasaurus Games Acquires New Game from Elizabeth Hargrave").
