Epiophlebia is the only known taxon of Odonata that is neither part of the damselflies (Zygoptera) nor dragonflies (Anisoptera). Previously, two species of Epiophlebia were recognized, restricted to areas in Japan (Epiophlebia superstes) and the Himalayas (Epiophlebia laidlawi). Recently, the group gained attention with the description of new species from China – Epiophlebia sinensis and Epiophlebia…
We used next-generation sequencing to characterise the complete mitochondrial genome of the damselfly Mnais costalis (Odonata, Calopterygidae). Illumina paired end reads were mapped against COI and 16S sequences from M. costalis and then extended using an iterative de novo map procedure. The final assembly was a contiguous sequence of 15,487 bp, which contained all standard mitochondrial…
We marked and released 276 F-0 larvae of Ophiogomphus rupinsulensis in the fall of 2008 in a 99-m riffle (marking riffle) of a small, serially discontinuous, northern Wisconsin river (USA). We then recovered marked exuviae via exhaustive collecting on the banks of a 272-m sampling reach in which the marking riffle was located during spring…
Paired extra-abdominal processes (ap) were found in the pleural region of abdominal segments 6–9 in adult Odonata for the first time. They are unsegmented bulge-like or rod-like structures of different size, degree of sclerotization and movability. A short search across odonatan families has shown that ap are inherent for all studied Aeshnidae and for some…
Oviposition in odonate females is usually considered finished when the female leaves the oviposition site. However, considering that many species lay their eggs within a set of bouts it is difficult to distinguish between the end of the oviposition bout and the end of the oviposition episode because the females can change the oviposition site…
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…
By means of slow-motion film analysis we found new female refusal behaviour patterns against male harassment in a variety of Odonata species. Often, females could escape simply by flying faster than males. Due to the morphological preconditions, there were differences in the two suborders. In Anisoptera, several behavioural specialities were analysed: (a) females of Aeshna…
While phylogeographic data provide valuable information to inform conservation plans, there are comparatively few Odonata phylogeographic studies. This lack of research is partially due to a lack of independent DNA markers with appropriate levels of polymorphism that PCR-amplify in a range of species. We followed an exon-primed, intron-crossing (EPIC) PCR strategy to develop five new,…
The present study provides the first odonate survey for the Brazilian Caatinga, including species habitat information. Specimens were collected during five days in both dry and rainy seasons of 2011 in the municipality of Itatira, state of Ceará, located in the semi-arid region of northeastern Brazil. Adult individuals of 37 species were documented, the highest…
Little is known about the ability of adult dragonfly individuals to survive into or over the winter in the Cape Floristic Region (CFR), a significant biodiversity hotspot in South Africa. Dragonfly species richness and abundance were recorded throughout winter and into spring in Jonkershoek Nature Reserve. Several environmental variables were also measured. Individuals of eight…
