The seasonal distribution of the two eastern U.S. species of embolemid wasps (Ampulicomorpha confusa and Embolemus nearcticus) in the Ouachita Mountains and Ozark Plateau of central and northern Arkansas is estimated from Malaise trap collections at 12 sites. In this limited study A. confusa appeared early in the season, whereas E. nearcticus was active during most of the summer season. Discontinuous morphological variation among the sampled male individuals of Embolemus was evident, possibly indicating the presence of undiagnosed species.
