Most specimens of Stenomorphus and Pogonodaptus have been collected at light, and their microhab- itat preferences are not well known. Members of S. californicus rufipes apparently live in open habitats away from water such as pastures and cultivated fields, whereas Pogonodaptus are more strongly associated with the margins of water bodies, where they have been observed to burrow into mud flats (Larochelle and Larivière 2003). Nothing is known about the feeding habits of either genus.

The rarity of Stenomorphus in Georgia and the Carolinas suggests that the specimens collected are strays rather than members of established populations. In the southwestern United States, Stenomorphus are often extremely abundant at lights (Ball et al. 1991), yet only four specimens have been collected at light in the Carolinas. Two of the South Carolina specimens were found indoors, and may have been transported by commerce.

The discovery of Pogonodaptus in eastern Georgia was unexpected. The locality is only 3 km west of the South Carolina border, and P. mexicanus likely occurs in that state as well. The lack of any other records of the species between Georgia and 272 Louisiana is difficult to explain. While P. mexicanus Seago provided access to the CMNH, and Charyn is very distinctive, its relatively small size could Micheli and Torsten Dikow allowed access to the make it easy to overlook with the naked eye.
