CENTRAL FLORIDA CRITTER OF THE DAY: Salt Marsh Moth Caterpillar (Estigmene acrea)
Native hosts include Dogfennel and other potentially aggressive species.
Serves as a host for other species such as tachinid flies and Hymenopterans (Bees, Wasps and Sawflies) which parasitized the eggs/larvae.
Larvae feed on a variety of plants including “cash crops”, so not a favorite with farmers.
This is an early instar.
Coloring can be highly variable: http://mothphotographersgroup.msstate.edu/species.php?hodges=8131
Shown on Florida Native Plant: BLUEJACKET; OHIO SPIDERWORT (Tradescantia ohiensis)
