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.
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.
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.
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.
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.
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.
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.
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. is described and illustrated based on a single male collected in Napo Province, Ecuador.
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.
