Paracoenia
shore flies
Paracoenia is a genus of shore flies (Diptera: Ephydridae) found in aquatic and semi-aquatic habitats. Species within this genus are associated with thermal springs, saline or alkaline lakes, and pond margins. Larvae develop in moist substrates at water edges, while adults and larvae feed on microorganisms including filamentous blue-green algae. The genus serves as an intermediate host for parasitic water mites and has been studied as an indicator of ecosystem stability in thermal environments.
Tethininae
Beach Flies
Tethininae is a subfamily of tiny acalyptrate flies within Canacidae, comprising over 115 species across seven genera. Formerly treated as family Tethinidae, the group is now recognized as paraphyletic. These drab-colored flies are strongly associated with maritime habitats, particularly intertidal zones and rotting seaweed accumulations. Despite their global distribution across all zoogeographic regions, many tropical species remain poorly documented.
