Agabus audeni
Agabus audeni is a predaceous diving beetle in the family Dytiscidae. It was described by Wallis in 1933 from a single type specimen collected in south-central British Columbia, and remained known only from that record until its rediscovery in the eastern foothills of the Rocky Mountains in southern Alberta. The species is morphologically similar to A. browni, with which it can be confused without careful examination.

Cicindelidia floridana
Miami Tiger Beetle
Cicindelidia floridana, the Miami Tiger Beetle, is a critically endangered species endemic to pine rockland habitat in Miami-Dade County, Florida. Rediscovered in 2007 after being presumed extinct since the 1940s, it is one of the rarest tiger beetles in North America. Adults are diurnal predators with brilliant coppery-green coloration, reduced elytral maculation, and distinctly punctured elytra with dense lateral pronotal setae. The species shows extreme habitat specificity to open sandy patches within fire-maintained pine rocklands, making it exceptionally vulnerable to urban development.

Cixius yufengi
Cixius yufengi is a species of planthopper in the family Cixiidae, described by Tsaur in 1993. The species belongs to a genus of small, often inconspicuous insects that feed on plant sap. Very little specific information is available about this particular species.

Dryotribus mimeticus
A weevil species first described by Horn in 1873, with a complex biogeographic history involving native North American populations and apparent human-mediated dispersal to Pacific islands. The species was considered extinct from 1986 until rediscovered in the Dominican Republic in 1997, with additional records from Montserrat in 2002. Its association with drift logs suggests a capacity for oceanic dispersal.

Panorpa floridana
Florida scorpionfly
Panorpa floridana, the Florida scorpionfly, is a rare endemic species in the family Panorpidae known only from two counties in northern Florida. Described as "cryptic" yet distinctive in appearance, it remained unrecorded for 28 years until its rediscovery in 2010 from a photograph taken at Gold Head Branch State Park in Clay County. The species is considered one of the most geographically restricted scorpionflies in North America.

Stonemyia velutina
velvety stonian horsefly, Volutine Stoneyian Tabanid Fly
Stonemyia velutina is a rare horsefly endemic to California, first described in 1892. The species was not observed between 1942 and 2023, leading to a premature declaration of extinction in 1996. Its 2023 rediscovery confirmed continued survival, though knowledge of its biology remains limited. The species belongs to the family Tabanidae, a group of biting flies whose females typically require blood meals for egg development.
