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…
A previous study has shown that wing size in Coenagrion puella varied considerably along a latitudinal gradient in the UK. Using landmark data from wing images, patterns of shape variation were also determined along the same transect by geometric morphometric analysis of wing shape. Wing shape was uniform at all sites other than those closest…
The maintenance of female colour polymorphism in coenagrionids is still an open issue. Here we ask if the three different female morphs of Coenagrion puella represent different reproductive traits in terms of clutch and egg size. Therefore clutch size and egg morphometry of the three female colour morphs were examined. We found that female colour…
Two third stadium larvae of Coenagrionidae (probably Coenagrion puella or Ischnura elegans) were recorded in the bladders of U. australis sampled from a garden pond in Karlsruhe, Germany, in June 2010. These are the first records of odonate larvae as prey of carnivorous aquatic macrophytes.
Microsatellites have been infrequently used for genetic analysis of odonate species. Here, we report four microsatellite loci that are polymorphic in Coenagrion mercuriale. Furthermore, we examine the success of cross-species amplification of a panel of 19 microsatellite loci that were developed from C. mercuriale in seven other European odonate species. PCR with microsatellite primers is…
