The larva of Epipleoneura manauensis is described and illustrated based on last-stadium larvae and exuviae of reared larvae collected in a black-water stream in Manaus, Amazonas State, Brazil. The larva of Roppaneura beckeri is described and illustrated based on exuviae of reared larvae collected from the water accumulated in the axils (phytotelmata) of Eryngium floribundum…
Dragonflies and damselflies (the Odonata) are among the most efficient flying insects. However, fragmentation of the landscape can increase distance between habitats and affect costs of dispersal, thus shaping phenotypic patterns of flight-related traits, such as wing shape, wing loading and wing size. Urban landscapes are highly fragmented, which limits dispersal among aquatic habitats. Hence,
The insects of the order Odonata have an aquatic larval stage and land-dwelling adults. These insects play an important role in aquatic ecosystems and are excellent bioindicators. The present study was based on a scientometric analysis of the research available on the Odonata, which aimed to identify the principal trends and gaps in the database…
