Bembix rugosa
Bembix rugosa is a species of sand wasp in the family Crabronidae, described by J. Parker in 1917. As a member of the genus Bembix, it shares the characteristic behaviors of solitary digger wasps that excavate burrows in sandy substrates and provision nests with paralyzed flies for their larvae. The species occurs in North America, though specific details about its biology and distribution remain limited compared to better-studied congeners such as Bembix americana.
Habroscelimorpha dorsalis
Eastern Beach Tiger Beetle
Habroscelimorpha dorsalis, the eastern beach tiger beetle, is a coastal tiger beetle species found on sandy beaches along the Atlantic and Gulf coasts of North America, ranging from the northeastern United States through Florida and into Mexico. Adults are active during summer months, foraging in intertidal zones for small invertebrates. The species has a two-year life cycle with larvae that construct vertical burrows in beach sand. One subspecies, H. d. dorsalis (Northeastern beach tiger beetle), is federally listed as threatened due to habitat loss from coastal development and recreational disturbance.
Habroscelimorpha dorsalis dorsalis
Northeastern Beach Tiger Beetle
The Northeastern Beach Tiger Beetle is the largest subspecies of Habroscelimorpha dorsalis, endemic to sandy Atlantic coast beaches of the northeastern United States. Listed as threatened under the U.S. Endangered Species Act since 1990, this diurnal predator has experienced severe population declines due to habitat loss from coastal erosion, shoreline development, and human recreational activity. Adults are active from mid-June through July, while larvae overwinter in deep sand burrows. The species serves as an indicator of beach ecosystem health and requires specific habitat conditions including medium-coarse sand and minimum beach widths of 6.5 feet for successful reproduction.
