Thirty-five dragonfly species are reported from Mongolia and Inner Mongolia. Three are first records. A non-parametric test is used to determine the total number of species to be expected. It suggests that the current number of 62 may be asymptotically complete, except for some specific zones like the Bulgan valley in the south-west, and the…

The microdistribution patterns of larval Gomphus graslinii and Oxygastra curtisii in three rivers in southern France were studied. While G. graslinii was caught mainly in sandy reaches covered with leaf litter, O. curtisii was found almost exclusively clinging to alder roots at the river margins. Preferences of habitat structure were determined from habitat selection experiments…
Predation of aggregated, ovipositing tandems of Sympetrum sanguineum and S. vulgatum by the hornet Vespa crabro was observed in Belarus. The same species of hornet was seen killing territorial males and copulating females of Calopteryx haemorrhoidalis in Italy. Numerous remains of these odonates at the oviposition sites suggest that attacks occur frequently. A short review…
The range of Macromia splendens, a rare anisopteran, includes SE France and some scattered localities on the Iberian Peninsula. During 1996-1998, I made an exhaustive search for the characteristics of the species’ larval and adult habitat, flight period and adult activity in NW Spain. Nine populations were found, greatly increasing its known range. Adults were…
