Chalcopteryx rutilans Rambur, 1842 (Polythoridae, Odonata) is a species widely distributed in central Amazonia. Due to its sensitivity environmental changes, it bioindicator used evaluate the conditions of streams federally protected areas. By sequencing C. mitogenome, we report first whole mitogenome from Polythoridae family and an Odonata endemic South America. The entire has 15,653 bp contai...

Only 8% of the approximately 120 conservation units in Minas Gerais State collect information on order Odonata, which motivated this study. We aimed to survey communities insect group Environmental Protection Area Machado River hydrographic basin, southern State, Brazil. For purpose, 12 areas were sampled by active searching from September 2018 March 2019. Representatives 71 Odonata species bel...

Ponds are sites of high biodiversity and conservation value, yet there is little or no statutory monitoring of them across most of Europe. There are clear and standardised protocols for sampling aquatic macroinvertebrate communities in ponds, but the most suitable time(s) to undertake the survey(s) remains poorly specified. This paper examined the aquatic macroinvertebrate communities from 95 p...

The female of Navicordulia aemulatrix Pinto & Lamas is described and illustrated for the first time based on a single specimen from the same locality of the type series (state of Santa Catarina, [municipality of São Bento do Sul, 26°14'58"S, 49°22'59"W, railroad station] Rio Vermelho, 29.I.1952, in MZSP). In addition, further morphological notes for the male are provided based on three specimen...

Organisms in the order Odonata are highly predatory insects that have a wide distribution globally. To date, there has been zero evidence that odonates employ luring as a means of prey acquisition. However, in this study, we show that Aeshna palmata larvae use abdominal movements to lure larval Argia vivida, subsequently consuming the lured organism. We also present findings of a similar behavi...
