Habitats and Life History
Habitats: Rehn and Hebard (1915) described obesa as "restricted to low, blackish, water-soaked ground covered with low bog plants (sun-dews, pitcher plants, etc.), in pine woods (long-leaf pine at all of the localities except Yemassee, where the forest was composed of the short-leaf species which is sometimes found in this region near swamps, so that even in it- limited range it- distribution is markedly discontinuous." Hubbell (1925) collected it at the margin of a dry cypress pond surrounded by pine woodlands in northern Florida. In Georgia, he found it in a patch of swampy woods with Swamp Blackgum, also bordered by a grove of Longleaf Pines. Hancock (1902) mentions one specimen collected from along a riverbank in Florida and "in the neighborhood of a swampy place." From these descriptions, this species appears to inhabit the shorelines of wetlands embedded within pine savannas, including depression ponds but possibly also including pocosin ecotones.

Comments: All of our records for this species appear to be more than 100 years old and were few in number to begin with. Rehn and Hebard (1915) found it as far north as New Bern but the majority of the records for this species are from Florida. Surveys need to be conducted in order to determine its current status as a resident species in North Carolina and to determine its range, abundance, and habitat preferences in our state.
