Sedge-associated
Guides
Arundanus
Arundanus is a genus of leafhoppers in the family Cicadellidae, subfamily Deltocephalinae, established by DeLong in 1935. The genus is associated with grassland and wetland habitats, with species often found in association with sedges and rushes. It belongs to the tribe Deltocephalini, one of the largest and most diverse groups of leafhoppers.
Carectocultus
Carectocultus is a genus of moths in the family Crambidae, subfamily Schoenobiinae. The genus was established by A. Blanchard in 1975 and contains three recognized species. Members of this genus are associated with wetland habitats and are distributed across parts of North America. The genus includes the species Carectocultus perstrialis, which was described as early as 1831.
Cerodontha feldmani
Cerodontha feldmani is a species of leaf miner fly in the family Agromyzidae, described by Eiseman and Lonsdale in 2018. The genus Cerodontha contains numerous small flies whose larvae create distinctive mines within plant tissues. As a member of this genus, it shares the characteristic biology of grass- and sedge-associated leaf miners, though species-level documentation remains limited.
Cylindridia
Cylindridia is a genus of flower weevils in the family Curculionidae, containing seven valid species. The genus was established by Casey in 1920 and has a broad distribution from Canada to Argentina. At least four species are known to develop within the culms of sedges (Cyperaceae).
Livia caricis
sedge psyllid
Livia caricis is a psyllid species in the family Liviidae, first described by Crawford in 1914. It belongs to the genus Livia, which comprises psyllids associated with sedges (Carex spp.). The species is found in western North America, with distribution records from British Columbia, California, Colorado, and Idaho. Like other psyllids, it is a small sap-feeding insect with host-specific relationships to its plant hosts.
Nascia acutellus
Streaked Orange Moth
Nascia acutellus, commonly known as the streaked orange moth, is a small crambid moth native to eastern and central North America. First described by Francis Walker in 1866, this species inhabits wet grassy areas with sedges. Adults are active from late spring through summer, with a wingspan of approximately 22 mm. The larval stage likely feeds on Cyperaceae (sedge family) species.
Phlegyas annulicrus
Phlegyas annulicrus is a true bug in the family Pachygronthidae, distributed from the southern United States through Mexico to Central America. It inhabits marshy and wetland habitats, feeding on seeds of sedges (Cyperaceae), particularly Cyperus species. The species undergoes five nymphal instars before reaching adulthood.
Sphenophorus costipennis
Sedge Billbug Weevil
Sphenophorus costipennis is a species of weevil in the family Dryophthoridae, commonly known as the Sedge Billbug Weevil. It is distributed across North America, with records from Canadian provinces including Alberta, British Columbia, and Manitoba. As a member of the genus Sphenophorus, it belongs to a group of weevils commonly referred to as billbugs, which are associated with various grass and sedge host plants. The species was described by Horn in 1873.
Taphrocerus chevrolati
Taphrocerus chevrolati is a species of metallic wood-boring beetle in the family Buprestidae. It is found in North America, with records from New Mexico, Arizona, and Alberta, Canada. Adults are associated with sedges and grasses, though larval host relationships remain unclear. The species was described by Obenberger in 1924.
Taphrocerus leoni
Taphrocerus leoni is a species of jewel beetle (family Buprestidae) described by Dugès in 1891. The species was historically considered Mexican but has been documented in the United States, with confirmed records from upper Miller Canyon in the Huachuca Mountains of southeastern Arizona. Adults are associated with sedges and can be collected by sweeping vegetation in riparian areas. The species is distinguished from congeners by its larger size, shiny appearance, and distinct pubescent maculations.
Taphrocerus schaefferi
Taphrocerus schaefferi is a species of metallic wood-boring beetle in the family Buprestidae. The species is a leaf-miner whose larvae develop within the leaves of yellow nutsedge (Cyperus esculentus). It is found in North America with records from the United States and Canada including Alberta, Ontario, and Saskatchewan.
