2021’s big content and usability update
Many new photos and usability improvements

Time for a large update, including lots of new content as well as large improvements in website usability!

Over the past months I’ve added a lot of new pictures to the already large collection. This update was long overdue: the new photos aren’t just from 2021 but 2020 as well. Among the many new additions are:

But that’s not all that’s new. A lot of effort was put into making this website more navigation- and search friendly.

  • Species pages now have secondary titles with Dutch, German and French common names;
  • Search results now show thumbnail pictures;
  • A new search option was added to the main menu.
  • A checklist of all European species was added. This checklist is basically a large searchable table with colums for family, scientific name, European English name (as used in K.D. Dijkstra’s excellent field guide), British and Irish name, Dutch name, German name and French name.

These additions may not look like large improvements but they provide a way better usability, especially for visitors who don’t know all the species by their scientific names.

More usability improvements and some large content updates are in the works. They’re planned for this winter. Enjoy and feel free to contact me if you want to provide feedback on these changes!

Greece – several species added

A trip to Greece in July of this year adds several species to this website. The total number of European species shown is now 112.

Species added in this update:

Pyrrhosoma elisabethae, one of the rarest Odonata species of Europe.

Vagrant Emperors, the story continues

Last June, The Netherlands were flooded with large numbers of Vagrant Emperors (Anax ephippiger), a dragonfly species primarily found in Africa and the Middle East. This influx was unique for more than one reason: the number of Vagrant Emperors was higher than all previous sightings combined, ever, and it was the first time we saw a real influx before summer. Mating and oviposition was witnessed on many Dutch locations. Now, in August, we see the results: for the first time in history, Vagrant Emperors emerge in The Netherlands.

Vagrant Emperors everywhere!

Right now The Netherlands are witnessing their largest known influx ever of Vagrant Emperor (Anax ephippiger). Vagrant Emperors are commonly found in Africa and southwest Asia but they are highly migratory and capable of travelling very large distances. There are several records from Iceland and even the Caribbean!

For the last week more Vagrant Emperors have shown up in The Netherlands every day and on many locations more than one individual was found. They show reproductive behaviour including ovipositing. The picture below was taken near the city of Weert in the south of The Netherlands. For more pictures of this stunning and interesting species, click here!
