Summary: The habitat preference of Libellula angelina was determined through field surveys, and the potential distribution and impact of climate-land cover changes were simulated using the MaxEnt model. The results showed that L. angelina prefers small inland wetlands, and the potential habitat area may increase in the future but is also at risk of loss due to wetland decline.

Summary: This study compared the body size of the endangered dragonfly species Nannophya koreana in two wetlands with significant differences in water temperature. Contrary to Bergmann's rule and the temperature-size rule, it was found that larvae in the colder water temperature region were smaller in size. The study highlights the importance of considering detailed factors such as habitat type when studying temperature-size responses in organisms.

Summary: This study assessed microplastic contamination in an edible aquatic insect living in rice fields and found microplastics in different parts of its body. The findings suggest that eating edible aquatic insects could be a pathway for humans to ingest microplastics.

Summary: The wing morphology of Trithemis dragonflies reflects environmental influence more than phylogenetic influence. It is important to carefully consider the sampling method in morphometric analysis, and if no prior information is available to guide sampling strategy, digital images or scans that represent the morphology comprehensively should be obtained.

Summary: This study found that the populations of Sympetrum species in South Korea should be considered as a single species based on morphological and molecular data. However, further research is needed to determine the independent species status in other countries.

Summary: This study used molecular and morphological analyses to determine the specific identity of dragonflies in the Galapagos Islands, identifying them as a continental species Tramea calverti rather than the previously considered T. cophysa. This shows that the species named after Darwin is a valid species inhabiting both the Galapagos islands and continental America.

Summary: The larva of Brachygonia Kirby, 1889 is described and illustrated for the first time based on the larvae of Brachygonia oculata (Brauer, 1878) discovered and successfully reared in Singapore, showing its similarity to species from the genus Brachydiplax Brauer, 1868.

Summary: Pantala flavescens, the most abundant and widely distributed dragonfly in the world, has a highly migratory capacity, making it an important model system for studying insect migration. The first complete mitochondrial genome of P. flavescens from a population in Tanzania was reported, providing insights into the evolutionary base of winged insects.

Summary: This study analyzed the records of Sympetrum genus from Thailand. It confirmed that the unidentified Sympetrum sp. reported from Chiang Mai and Loei provinces is S. hypomelas (Selys, 1884), and additional provincial records of this species were provided. A new species, Sympetrum thailandensis sp. nov., was described and illustrated based on adult specimens from Nakhon Nayok province, Central Thailand. It belongs to the infuscatum-group and is most similar to S. darwinianum (Selys, 1883), but differs in morphological and coloration characters. A key to Sympetrum species known from Thailand is also presented.

Summary: The mitochondrial genome of Neurothemis fulvia, a dragonfly of wet forests, was sequenced and analyzed in this study. It is 15,459 bp long and contains 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes. Most protein-coding genes in N. fulvia start with ATN codons and end with TAA or TAG codons, except for cox1 and nad1. Phylogenetic analysis revealed a close relationship between N. fulvia and Tramea virginia.

Summary: Environmental alterations resulting from shifts in land use can impact the behavioral diversity of adult odonates. Some sites impacted by anthropogenic changes show a loss of behaviors, while certain morphological and behavioral traits of odonates vary under specific environmental conditions. Consideration of behavioral traits is highlighted as crucial in conservation strategies to address specific extinction pressures faced by species with unique behavioral repertoires.
