Looking out for the little guy: species distribution modeling and conservation implications of the elfin skimmer Nannothemis bella (Odonata: Libellulidae)
Nannothemis bella Uhler, 1857 (Odonata: Libellulidae), the smallest dragonfly in North America, inhabit bogs and sedge fens across their distribution, spanning from Quebec (Canada) south to Florida and west to Minnesota and Louisiana (USA).
A new species of Philosina Ris, 1917 (Zygoptera) from China
A new species Philosina nigromacula Yu & Jin, 2024 is described from Sichuan, southwest China, with paratypes from Sichuan and Jiangxi, east China. The new species is generally similar to Philosina buchi Ris, 1917 but has a different abdominal color pattern.
Melanoneura agasthyamalaica sp. n. (Odonata, Platycnemididae) from the Western Ghats, India
Melanoneura Fraser, 1922 is a genus of damselflies which was, to date, regarded as monotypic. It is represented by the nominate species, Melanoneura bilineata Fraser, 1922 which is endemic to the Western Ghats in India.
Odonata assemblages at two urban wetlands in West Bengal, India
Adult Odonata represent valuable indicators of natural habitat quality, ecosystem integrity, and pollution status in freshwater ecosystems. This study aimed to investigate how varying climatic condition, sub-habitat types, and physicochemical ambience of wetlands impact Odonata diversity.
Urban stormwater ponds can support dragonfly reproduction akin to natural ponds
Stormwater ponds are constructed to receive urban runoff and regulate flooding of built areas. As a result, they can be more stressful habitats for aquatic organisms than natural ponds.
Land use and beyond: unraveling environmental determinants of odonate assemblages in northeastern Algeria
Freshwater ecosystems, recognized as hotspots of biodiversity, are under increasing threat from human activities. Odonata, the iconic inhabitants of these ecosystems, are highly sensitive to changes in habitat morphology, hydrology and land-use dynamics.
A decadal-scale qualitative comparison of lotic Odonata nymph surveys in northwestern Pennsylvania, USA, reveals possible assemblage restructuring
Detecting long-term changes to Odonata assemblages requires repeated sampling at fixed locations over decadal periods. However, few such biomonitoring efforts exist for Odonata, especially at low taxonomic resolution and immature life stages.
Demography and natural history of the damselfly Mesamphiagrion gaudiimontanum (Coenagrionidae), a Páramo endemic species in the Colombian Andes
The páramos are high mountain ecosystems in the tropical regions of the New World, and they are particularly threatened by climate change. The Belmira páramo
complex in Colombia is home to Mesamphiagrion gaudiimontanum, an endemic and endangered damselfly species.
Commented checklist of the Odonata from Colombia
Colombian odonatological history was scarce until two decades ago. Here, we present an updated, thoroughly vetted, and refined checklist of taxonomic and geographical records of Colombian odonates, built upon the previous publication in 2011.
Reproductive behavior of Erythrodiplax abjecta (Rambur, 1842) from Andean Mountains
Research about the behavior of Neotropical species is crucial to understand how the rapid environmental changes in the Neotropics affect the reproduction of various organisms. The reproductive behavior of insects in tropical ecosystems, such as those belonging to the order Odonata, is as yet scarcely known. In this article, the reproductive behavior of Erythrodiplax abjecta is described from several localities in the Colombian Andean Mountains.
Evaluation of speculated reproductive habitat for Somatochlora calverti (Corduliidae), a rare and range-restricted dragonfly
Globally, freshwater ecosystems and the organisms that depend on them are at risk. Dragonflies and damselflies (collectively, “odonates”) have a history of being used as bioindicators of freshwater habitat quality due to their wide range in environmental sensitivities across species and because they are relatively accessible.
Geographical variation in size of the three final stadia of Cordulegaster boltonii (Donovan, 1807) larvae in the Iberian Peninsula (Odonata: Cordulegastridae)
A two-variable analysis of male and female Cordulegaster boltonii larvae (head width and hindwing sheath length) in specimens from five Iberian populations was carried out with the objective of ascertaining whether these traits differ between populations.
Paleoecological niche modeling of Epiophlebia (Epiophlebioptera: Epiophlebiidae) reveals continuous distribution during the Last Glacial Maximum
Disjunct biogeographic patterns of similar species remain enigmatic within evolutionary biology. Disparate distributions typically reflect species responses to major historical events including past climate change, tectonics, dispersal, and local extinction.
Rare and endangered Odonata of Lebanon – an update with a discussion on the vanishing Levant endemic dragonfly fauna
The Levant is a hot spot of biodiversity, even for Odonata. Approximately 90 Odonata species were recorded for the Levant and 48 from Lebanon. Lebanon, as a central part of the Levant, was visited in 2022 and 2023 for searching dragonflies.
Increased geographic sampling suggests incomplete lineage sorting and recent introgression between Pyrrhosoma nymphula (Sulzer, 1776) and P. elisabethae Schmidt, 1948 in the Western Palearctic
We analysed COI and ITS sequences from a total of 69 European Pyrrhosoma nymphula (Sulzer, 1776) and three P. elisabethae Schmidt, 1948 to explore species boundaries and phylogeographic patterns in their Western Palearctic distributions.
Description of Phylloneura rupestris sp. n. (Odonata, Platycnemididae) from the Western Ghats, India, with notes on its reproductive behaviour
Phylloneura Fraser, 1922 is a genus of damselflies that, to date, has been regarded as monotypic, represented solely by Phylloneura westermanni (Hagen in Selys, 1860) which is endemic to the Western Ghats of India.
Gomphomacromia signata sp. n. from the Andes Mountains in Ecuador (Odonata: Synthemistidae)
Gomphomacromia signata sp. n. is described and illustrated based on a single male collected in Napo Province, Ecuador.
The final-instar larva of Bayadera strigata Davies & Yang, 1996 from Yunnan, China (Odonata: Zygoptera: Euphaeidae)
The final instar of Bayadera strigata Davies & Yang, 1996, from Yunnan Province, China, is described and illustrated for the first time. This study confirms several characters as being typical of, or unique to, the genus Bayadera and discusses them in comparison to other genera.
Life cycle and seasonal regulation of Onychogomphus forcipatus unguiculatus in the Seybouse River, Algeria (Insecta: Odonata)
Understanding the seasonal regulation and life cycle patterns of Odonata is critical to identifying the factors that influence their voltinism. While the life history and seasonal regulation of Odonata, particularly gomphids, has been studied extensively, few studies have focused on North African gomphids.
