The Estigmene acrea is an interesting species of moth found in several regions of North and South America and Africa. These moths were named salt marsh moths due to being commonly found in salty marsh habitats, as well as in other open regions. It is part of the superfamily Noctuoidea, which also includes the garden tiger moth.

These moths appear white in color with yellow-orange abdomens and black spots. The larvae are quite hairy and appear reddish-brown, yellow, and black. The salt marsh moth mating ritual involves males releasing pheromones to attract females and adult moths leave their pupa during the spring season. Salt marsh caterpillars act as pests and destroy important crops like cabbage, potato, and tobacco. Particularly, in Ontario and Quebec in Canada, they have caused extensive damage to crops. Insecticides are used by people in order to stop the destruction inflicted by these creatures.

The eggs hatch after four or five days and larvae come out which go through between five and seven instar phases. These insects can spend up to 45 days as caterpillars before making their own cocoon with the silken hairs on their body. They spend the winter in the pupal stage and emerge in the spring season, following which the same life cycle repeats itself.
