Rediscovery of Pogonomyrmex badius (Latreille) (Hymenoptera: Formicidae) in Mainland Mississippi, with an Analysis of Associated Seeds and Vegetation

Pogonomyrmex badius (Latreille)was considered to be a relatively common species in central and southern Mississippi before the introduction of the imported fire ants, Solenopsis invicta and S. richteri, and before subsequent area wide control measures, but it has not been reported from the mainland since the mid 1930's. Recent collections in a relic sandhill community in Smith County have resulted in the rediscovery of this species in central Mississippi. Colony characteristics and microhabitat of P. badius are described. Observations of P. badius and other ant species found walking on the P. badius craters are provided. Seeds found in middens and caches were identified, and charcoal pieces found on the mounds were identified and measured.
