Cerodontha scirpi
Cerodontha scirpi is a leaf miner fly in the family Agromyzidae. The species name 'scirpi' refers to its association with sedges (genus Scirpus). Larvae mine between the layers of grass blades and leaves of sedges and rushes. It is recorded from North America and Europe.
Dolerus versus
Dolerus versus is a species of sawfly in the family Tenthredinidae. The genus Dolerus comprises medium to large sawflies commonly associated with grasses and sedges. Like other members of the subfamily Dolerinae, adults are typically active in spring and early summer. The larvae feed on monocotyledonous plants and can be distinguished from lepidopteran caterpillars by having six or more pairs of prolegs rather than five or fewer.
Haplaxius crudus
American Palm Cixiid, palm leafhopper
Haplaxius crudus is a cixiid planthopper and the primary known vector of lethal yellowing phytoplasma, a devastating disease of palms. The species has a complex life cycle split between two distinct host groups: nymphs develop on grasses and sedges, while adults feed exclusively on palms. This host alternation makes management challenging, as nymphs and adults occupy different habitats. The species is economically significant across the Caribbean, Florida, and tropical America, where it has caused millions of palm deaths and substantial agricultural losses.
Schoenobiinae
Schoenobiinae is a subfamily of grass moths (Crambidae) established by Duponchel in 1846. The group comprises approximately 30 genera including Schoenobius, Scirpophaga, Donacaula, and Catagela. Many species are stem borers of monocot plants, with larvae feeding internally in stems of grasses, sedges, and rushes. Some genera contain significant agricultural pests, particularly of rice and other cultivated cereals.
