A high-resolution photographic library of wings of Australian dragonflies and damselflies. Using specimens from the Australian Museum and other collections, images of wings of both male and female dragonflies and damselflies found in Australia are available for identification and research. Volume 1. Anisoptera (dragonflies) https://doi.org/10.6084/m9.figshare.11845230 Volume 2. Zygoptera (damselflies) https://doi.org/10.6084/m9.figshare.12579959 Both male and female wings of 318 species of dragonfly and damselfly wings, order Odonata, have been photographed with a specialist set-up using identified museum collection material. Each image shows a pair of right wings, a scale, an identifying taxonomic name and gender. Images hold extensive embedded metadata: 1. Metadata associated with the camera and photograph – embedded as Exif metadata 2. Metadata about the specimen – embedded as IPTC metadata o Registration number o Institution o Taxonomic name, according to the Australian Faunal Directory o Georeference, extracted from any occurrence data held by Atlas of Living Australia o Gender 3. Title and caption metadata – embedded as IPTC metadata. Caption information includes common name, taxonomic name, institution and specimen registration number. 4. Other general metadata to enable harvesting of images – embedded as keywords o Country o Taxonomy o Image descriptorsPurpose
An open resource for identification and researchSampling Description
Quality Control
Each image shows a pair of wings on a white background with a scale bar and identification. Size: 9008 x 5067 pixel (ratio 16:9) Colour palette: 24 bits per pixel Scale: Most dragonfly and damselfly wing images were photographed at a resolution of 1357 pixels per centimetre, or about 7 µm per pixel. Some larger wings were photographed at a resolution of 1000 pixels per centimetre, or about 10 µm per pixel.Method steps
- These high-resolution images were made by John Tann at the Australian Museum using identified collection material from that museum and other Australian collections.
Additional info
For some species undamaged right wings were not available and left wings were used as substitutes. When this occurred a mirror image of the left wing was created in software so as to appear like a right wing. This modification is noted in the image metadata.Taxonomic Coverages
