Flight of the dragonflies and damselflies
This work is a synthesis of our current understanding of the mechanics, aerodynamics and visually mediated control of dragonfly and damselfly flight, with the addition of new experimental and computational data in several key areas. These are: the diversity of dragonfly wing morphologies, the aerodynamics of gliding flight, force generation in flapping flight, aerodynamic efficiency, comparativ...

متن کاملA Feature-based Classifier for Dragonflies and Damselflies
Unique patterns present in the wings of dragonflies and damselflies can be used to determine their family, genus, and species. A method for classifying dragonflies and damselflies using a particular pattern known as the triangle was developed using scanned images of the wings. Digital image processing techniques, such as image segmentation and feature detection, are used to determine properties...
متن کاملDragonflies (Odonata) from South-Eastern Iran
Twenty-seven species of Odonata were collected in the present survey in the freshwaters of South-Eastern Iran, Kerman province, in contrast to 11 species that were recorded previously from this region. In this study, 528 specimens were collected from more than 30 sites in Kerman province during 2006-2008. It seems that in this region due to its special biogeographic conditions, species diversit...
متن کاملPhylogeny affects host's weight, immune response and parasitism in damselflies and dragonflies
Host-parasite interactions are an intriguing part of ecology, and understanding how hosts are able to withstand parasitic attacks, e.g. by allocating resources to immune defence, is important. Damselflies and dragonflies show a variety of parasitism patterns, but large-scale comparative immune defence studies are rare, and it is difficult to say what the interplay is between their immune defenc...
