Guides
Choroterpes
Choroterpes is a genus of mayflies in the family Leptophlebiidae, distributed across the Americas, Europe (excluding the British Isles), Africa, and Asia. The genus contains multiple subgenera, including the nominate subgenus Choroterpes and Neochoroterpes (North America). Nymphs are typically found in streams and rivers, often associated with leaf litter. The genus has been subject to taxonomic revision, with some species reassigned to new genera such as Tikuna.
Leptophlebia cupida
Early Brown Spinner, Black Quill
Leptophlebia cupida is a pronggilled mayfly species native to North America, commonly known as the early brown spinner or black quill. The species exhibits a univoltine life cycle with egg diapause during summer months. Nymphs develop through approximately 20-34 instars over 10 months, with emergence occurring from late April to mid-May. Adults are short-lived, non-feeding, and mate in swarms near streams.
Leptophlebia intermedia
Leptophlebia intermedia is a species of pronggilled mayfly in the family Leptophlebiidae. It was described by Traver in 1932. The species is found in North America.
Leptophlebia nebulosa
prong-gilled mayfly
Leptophlebia nebulosa is a species of prong-gilled mayfly in the family Leptophlebiidae. It is found in North America. The species belongs to a group characterized by their forked or prong-like gills, a distinctive morphological feature of the family Leptophlebiidae.
Neoleptophlebia assimilis
Southeastern Prong-gilled Mayfly
Neoleptophlebia assimilis is a species of prong-gilled mayfly in the family Leptophlebiidae. It is known from the southeastern United States. The species belongs to a genus characterized by gills with divided, finger-like lobes. Mayflies in this family are typically associated with running water habitats and serve as important indicators of water quality.
Neoleptophlebia mollis
soft prong-gilled mayfly
Neoleptophlebia mollis is a species of prong-gilled mayfly in the family Leptophlebiidae. The species was first described by Eaton in 1871. It belongs to a genus characterized by forked gills on abdominal segments, a trait reflected in the common name "prong-gilled mayfly." The specific epithet "mollis" (Latin for "soft") likely refers to some aspect of the species' morphology or texture.
Paraleptophlebia debilis
mahogany dun
Paraleptophlebia debilis, commonly known as the mahogany dun, is a species of pronggilled mayfly in the family Leptophlebiidae. It was first described by Francis Walker in 1853 under the basionym Baetis debilis. The species is found in North America, though specific details about its ecology and biology remain limited in available sources.
Paraleptophlebia guttata
dappled prong-gilled mayfly
Paraleptophlebia guttata is a prong-gilled mayfly in the family Leptophlebiidae. Adults are known from southeastern Canada, northern Canada, and the eastern United States. The species is part of a diverse genus of stream-dwelling mayflies characterized by forked gills on abdominal segments.
Paraleptophlebia helena
pronggilled mayfly
Paraleptophlebia helena is a species of pronggilled mayfly in the family Leptophlebiidae. The species was described by Day in 1952 and is known to occur in North America. As a member of the Leptophlebiidae, it possesses the characteristic forked gills (pronggills) that give the group its common name.
Paraleptophlebia strigula
streaky prong-gilled mayfly
Paraleptophlebia strigula is a species of prong-gilled mayfly in the family Leptophlebiidae. It was described by McDunnough in 1932. The species occurs in North America. As a member of Leptophlebiidae, it possesses the characteristic forked gills on abdominal segments that give the family its common name.
Paraleptophlebia vaciva
pronggilled mayfly
Paraleptophlebia vaciva is a species of pronggilled mayfly in the family Leptophlebiidae. It is found in southwestern Canada, the northwestern United States, and Alaska. As a member of Leptophlebiidae, it possesses the characteristic forked gills on abdominal segments that give the group its common name.
Thraulodes speciosus
Thraulodes speciosus is a species of mayfly in the family Leptophlebiidae, described by Traver in 1934. It belongs to the order Ephemeroptera, an ancient group of aquatic insects with brief adult stages. The genus Thraulodes is distributed across the Nearctic and Neotropical regions. Like other leptophlebiid mayflies, this species has aquatic nymphal stages and terrestrial adults that do not feed.
