About the Project | TOWD Project
The Targeted Odonata Wing Digitization (TOWD) Project is part of an NSF-funded, multi-institutional effort to develop ODOMATIC, software for automatically identifying Odonata from images. Initiated in 2016, the TOWD Project aims to digitize the world’s dragonfly and damselfly species, starting with the approx. 466 North American species.

So the wing vein patterns in dragonfly wings are directly correlated with flight style. [Dragonflies swoop and hover over a sunlit field.] WARE: We generally group dragonflies into two styles—fliers and perchers. [A split screen shows a stocky, hovering dragonfly on the top, and a dragonfly with boldly striped wings perched on a twig on the ...
The damping and structural properties of dragonfly and damselfly wings ...
2021年6月15日 · A growing body of research on wing biomechanics gives an increasingly clear picture of the influence of the design and material properties of insect wings on their deformations under typical ...
The secret of dragonflies' flight - Phys.org
2014年11月25日 · By tracking the body and wing orientations using high-speed video recording of this rapid roll in high resolutions, the team uncovered how dragonflies were altering the aerodynamics on their...
At a glance, you can see that a dragonfly has a prominent head, an elongated body, and two pairs of slender wings extending to each side. As it takes off, the wings appear as a blur. In air, the dragonfly dances in unpredictable steps, hovering briefly then quickly moving to a new location.
Dragonflies use vision, subtle wing control to straighten up and fly ...
2022年5月13日 · That visual cue triggers a series of reflexes that sends neural signals to the dragonfly’s four wings, which are driven by a set of direct muscles that modulate the left-wing and right-wing pitch asymmetry accordingly. With three or four wing strokes, a tumbling dragonfly can roll 180 degrees and resume flying right-side up.
How dragonflies use ultrafast wing movements to flip over in flight
2022年5月12日 · Dragonflies use a combination of visual cues and precise control of their wing pitch to perform aerial acrobatics. The four-winged insects can rapidly right themselves from an upside-down...
How dragonfly wings get their patterns - ScienceDaily
Leonardo di Vinci, famously inspired by dragonfly flight, sketched dragonfly wings in the early 1500s. Dutch biologist Jan Swammerdam made extraordinarily detailed illustrations of wing...
How do dragonfly wings work? — Worldwide Dragonfly …
Dragonfly (Anisoptera) wings represent an extreme example of this automatic shape control among flying insects. The functionality of the wings results from complex interactions between several structural components of which they are composed.
The structure and mechanical properties of dragonfly wings …
2012年1月1日 · The wings of dragonflies are mainly composed of veins and membranes, a typical nanocomposite material. The veins and membranes have a complex design within the wing that give rise to whole-wing characteristics which result in dragonflies being supremely versatile, maneuverable fliers.
