Odontomachus relictus
Florida Scrub Trap-jaw Ant
Odontomachus relictus is a species of trap-jaw ant endemic to Florida, where it inhabits endangered scrub habitat on ancient sand ridges. It was described by Deyrup & Cover in 2004. Research suggests that populations on separate sand ridges may represent distinct species, which would make them among the rarest ants in North America. The species possesses the characteristic spring-loaded mandibles of the genus Odontomachus.
Ospriocerus
robber flies
Ospriocerus is a genus of robber flies (family Asilidae) containing approximately 17 described species. These large, predatory flies are primarily associated with grassland and prairie habitats across western North America. Several species exhibit mimetic coloration resembling spider wasps (Pompilidae), with black bodies and red or orange abdominal markings. The genus has been documented as far north as Canada and south into Mexico. Species such as O. abdominalis represent significant range extensions when found in eastern localities, highlighting the importance of remnant prairie conservation.
Tetraopes quinquemaculatus
five-spotted milkweed beetle
Tetraopes quinquemaculatus is a milkweed-associated longhorn beetle (Cerambycidae) described by Haldeman in 1847. It is native to North America and is one of several species in the genus Tetraopes that specialize on milkweeds (Asclepias). The species is considerably less common than the widespread T. tetrophthalmus and has been documented from sand prairie and dry sandy habitats in the Mississippi River Alluvial Basin. Adults are visually distinctive and larvae develop as root borers in living milkweed plants.
