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 کاملNew Eocene damselflies and first Cenozoic damsel-dragonfly of the isophlebiopteran lineage (Insecta: Odonata).
The study of a new specimen of Petrolestes hendersoni from the Eocene Green Formation allows a more precise description of the enigmatic damselfly and the diagnosis of the Petrolestini. Petrolestes messelensis sp. nov. is described from the Eocene Messel Formation in Germany, extending the distribution of the Petrolestini to the European Eocene. The new damsel-dragonfly family Pseudostenolestid...
متن کاملDamselflies (Zygoptera: Odonata) of Pakistan: Part 1
The present study is an effort to document bio-geographical distribution for Zygoptera of Pakistan. Damselflies were collected throughout the country and territory of Azad Jammu and Kashmir during 2004-2009. A total of 2692 specimens were collected yielding 9 families, 21 genera, and 48 species and subspecies. Three of these species, Libellago lineata lineata (Burmeister), Elattoneura atkinsoni...
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 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...
