A rheophile is an animal that prefers to live in fast-moving water.
Troides hypolitus, the Rippon's birdwing, is a birdwing butterfly endemic to the Moluccas and Sulawesi. It is not significantly threatened, but it is protected.
Elattoneura caesia is a species of damselfly in the family Platycnemididae known commonly as the jungle threadtail. It is endemic to Sri Lanka, where it is distributed across the central and southern parts of the island. It lives in streams and springs in primary rainforest habitat. It is considered to be vulnerable because of the destruction and degradation of local rainforest habitat.
Elattoneura, the African threadtails, is a genus of damselflies in the family Platycnemididae. They were formerly placed in genus Prodasineura, but form a distinct clade. The adults are smallish and delicately built damselflies, and their males have very wide heads. The adults are typically found in sheltered locations beside or over running water, though a few prefer calmer water with much detritus. There appears to be two groups with differing habitat preferences. Those with pruinose faces and mostly blue eyes occupy watercourses in open terrain, while those with black or brightly coloured faces are found along forested streams.
Elattoneura glauca is a species of damselfly in the family Platycnemididae. It is known also as the common threadtail, the grey threadtail or gewone draadstertjie. It is native to the southern half of the African continent, where it is widespread. It lives in shady areas along rivers and streams.
Elattoneura leucostigma is a species of damselfly in the family Platycnemididae known commonly as the smoky-winged threadtail. It is endemic to Sri Lanka, where it is known from only one location. It has not been found in any recent surveys. It is known from streams in dense forest habitat, and the area has undergone habitat destruction and pollution of local waterways.
Elattoneura nigra is a species of damselfly in the family Platycnemididae known commonly as the black threadtail. It is native to Central Africa, where it is widespread. It lives along streams and rivers.
Elattoneura pasquinii is a species of damselfly in the family Platycnemididae. It is endemic to Ethiopia. It is known from only three sites along streams and rivers.
Prodasineura flavifacies is a species of damselfly in the family Protoneuridae. It is endemic to Zambia.
Prodasineura, the Asian threadtails, is a genus of damselflies in the family Protoneuridae. All the Afrotropical species formerly in this genus are now placed in Elattoneura, the African threadtails. Dijkstra et al. (2014) moved the genus from Protoneuridae to Platycnemididae based on molecular phylogenetic research.
Elattoneura frenulata is a species of damselfly in the family Platycnemididae known commonly as the sooty threadtail or Roetswartdraadstertjie. It is endemic to South Africa. It is a localised endemic of montane areas of the Western Cape, marginally expanding into the western parts of the Eastern Cape. Though it has a restricted distribution, it is locally common. It lives near slow-moving rivers with abundant vegetation.
Elattoneura oculata is a species of damselfly in the family Platycnemididae known commonly as the two-spotted threadtail. It is endemic to Sri Lanka, where it is a rare species known from a few locations in the southern and central parts of the island. It lives along streams in primary rainforest habitat, an ecosystem threatened by habitat destruction and degradation.
Elattoneura centralis is a species of damselfly in the family Platycnemididae known commonly as the dark-glittering threadtail. It is endemic to Sri Lanka.
Elattoneura tetrica, the black and yellow bambootail, is a damselfly species in the family Platycnemididae. It is endemic to Western Ghats in India.
Elattoneura souteri is a damselfly species in the family Platycnemididae. It is endemic to Western Ghats in India.
Sphacophilus cellularis is a species of sawfly in the family Argidae.
