End 2005 initiative was taken to gather an European atlas of dragonflies. The project is being supported by the dutch European Invertebrate Survey and coordinated by Vincent Kalkmann of Naturalis - National Museum of Natural History in the Netherlands.
The result of this project, spanning 41 countries, is going to be the atlas itself in form of a book. It will contain introductory chapters followed by species accounts for each of the 130+ species encountered in Europe. Each account containing a distribution map and brief information on taxonomy, life history, habitat, flight histograms and conservation status.

Recently a fair amount of my spare time has gone into sorting through the dragonfly collections kept at the Natural History Museum Aarhus. Some of the animals have been ID’ed by the collector and a lot are just tagged with a date and location and pinned. So the job so far has been to double-check identification and identify those that haven’t been given a name yet, note all the info on the collected animal, add co-ordinates and save the lot in a rapidly growing database.
It’s quite fun and a learning experience to sort through all this material. It provides a great opportunity to compare tricky traits between resembling species. (I’ll see if I can use some of those comparisions for a post later on.)
It’s also quite fascinating to see in how good shape some of the animals are, despite being collected back in 1896. (That’s like.. a very very… long time for something that was only meant to last a few months).
A larvae of the Blue Emperor (Anax imperator) awaiting unknowing prey to happen by. This exemplar was photographed in an aquarium early spring 2009 before being slipped back to its pond.
We’re soon done with the dry-collection. Next step; the alcohol preserved imagos and a few thousand larvae.
So far the schedule is to have a final database during this spring.
