About Deielia phaon
Deielia phaon is a member of Libellulidae in the order Odonata. Its recorded origin status on Kauaʻi is introduced.
Deielia phaon (Deielia phaon) is documented from Kauaʻi. Skimmer dragonflies have aquatic predatory naiads and aerial predatory adults. Many species are strong dispersers and use ponds, marshes, streams, or temporary water. On Kauaʻi, observations are most useful when they record waterbody, exuviae/naiads, adult sex/color phase, territorial behavior, and season. Where island-specific host, prey, breeding-site, abundance, or seasonal information is not yet firmly documented, those details should remain tied to direct specimens and field observations rather than inferred from populations elsewhere.
Deielia phaon is an introduced skimmer dragonfly documented from Kauaʻi under the historical name Deielia fasciata.
Kauaʻi occurrence evidence: Waimea River Kauaʻi survey lists legacy Deielia fasciata as introduced; ITIS treats D. fasciata as an invalid junior synonym of valid Deielia phaon and lists the valid species as introduced in Hawaiʻi.
The cited occurrence evidence does not by itself establish current abundance or population trend on Kauaʻi.
Life cycle
Egg; aquatic naiad; emergence/final molt; winged adult; no pupa.
Habitat
Freshwater pools, ponds, wetlands, slow streams, and surrounding aerial foraging habitat.
Food and ecological role
Naiads prey on aquatic animals; adults capture flying insects.
Reproduction
Adults mate near water and females lay eggs in or over suitable freshwater habitat.
Movement
Adults are strong fliers; naiads remain aquatic.
Ecosystem role
Predator in aquatic and aerial food webs.
Threats and impacts
Recruitment depends on freshwater habitat quality; introduced species may also interact with native odonates.
Monitoring
Record waterbody, exuviae/naiads, adult sex/color phase, territorial behavior, and season.
