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 (more...)

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.
