Dragonflies and damselflies are hosts to a variety of parasites and pathogens. However, very few studies have investigated which viruses infect dragonflies and damselflies. Here, based on next generation RNA sequencing of RNA from Leucorrhinia dubia (Libellulidae, Anisoptera) and Coenagrion puella (Coenagrionidae, Zygoptera) larvae, data on putative viruses present in odonates are reported. In both…
The Palaearctic libellulid Leucorrhinia pectoralis is generally considered to be a species inhabiting fish-free water bodies. Yet, a long-term monitoring study of 38 water bodies in NE Germany resulted in 16 species offish being recorded in reproductive habitats of L. pectoralis, with Rutilus rutilus and Carassius carassius as the most numerous and widespread fish species.
I compared males of Leucorrhinia intacta collected at two permanent and two previously dried ponds to assess whether males colonizing formerly dried sites differed in morphology or level of mite parasitism from males at permanent sites. Males colonizing sites that had local extinctions in the previous year due to pond drying were more similar to…
The final-stadium larva of Leucorrhinia patricia Walker is described from six exuviae with associated teneral adults collected in northern British Columbia. L. patricia belongs to the group of nearctic Leucorrhinia that has larvae with three ventral stripes. The larvae are very similar to those L. hudsonica (Sélys) larvae that are small and lack dorsal spines….
A brief account is presented of mass dragonfly migrations observed previously in Russia and West Siberia in particular. A mass migration in Libellula quadrimaculata is described in detail. It occurred on 1 July 1981 in the south-western part of the West Siberian Plain in the valley of the Ishym River. From 1968 to 2008 we…
