Population size in Epitheca bimaculata varied considerably with time in northeastern France. However, emergences were always synchronised with an EM50 percentile ranging from four to eight days, irrespective of the population size. The sex ratio of all exuviae collected at one locality varied from ca 0.7 to ca 1.0, depending on the year. Larval dev...

Dragonflies and damselflies are some of the most beautiful, fragile and resilient insects found in the natural world. With their complex behaviours, astonishing aerobatic skills and preference for freshwater habitats, they are a very rewarding group of animals to observe in the field. Dragonflies and Damselflies of Britain and Western Europe featu...

Based on numerous records of Orthetrum ransonnetii from south-eastern Arabia, the Middle East, the Maghreb and the Canary Islands in recent decades, the range of this species is characterised in relation to climate and habitat parameters. The species is mostly found in hot, arid, rocky environments. Its flight period extends year-round, with an app...

Seven species of damselflies of the genus Ischnura are found in the Middle East. The species can be hard to identify and show considerable variation within individuals. The purpose of this paper is to provide identification for these species with particular reference to those from Oman and the United Arab Emirates. Simply relying upon colour patter...

A new Israeli population of Pseudagrion torridum, discovered in summer 2013 near Tel-Aviv, Israel, is described. This population is highly heterogeneous, with individuals resembling the nominotypical subspecies and others, particularly females, resembling the subspecies P. t. hulae. The infraspecific taxonomy of P. torridum is critically discussed.

North African odonates are facing conservation challenges, not only by increased degradation and loss of habitat, but also by having poorly understood taxonomy. Coenagrion puella is a widely distributed damselfly but there is debate about the taxonomic status of North African populations, where the species is very rare. We evaluate the genetic dist...

The exuviae of all four species of Urothemistinae known from the Arabian Peninsula (Macrodiplax cora, Selysiothemis nigra, Urothemis edwardsii and U. thomasi) were collected on recent surveys in UAE and Oman.
