Great photo by David McClure, who captured this pair of Monarchs who may be ready to mate! Taken at DeKorte this past Sunday.

According to NJSEA naturalist Aleshanee Mooney:

Mating monarchs could stay connected all day, even when one of them flies around. The male is the one with its wings spread out. You can see the pheromone glands on the male’s bottom wings.
