This video provides an up-close and personal view of dragonflies. See them fly in slow motion, eat insects, and breathe through spiracles (holes) in their abdomens.
Despite their name, dragonflies are not related to common flies. In fact, they are part of an entirely different group of insects. Dragonflies are part of the Odonata Order, which have roamed Planet Earth for approximately 300 million years.
Dragonflies are predators, feeding on creatures smaller than themselves. They are useful in controlling mosquitos. They have large multifaceted (compound) eyes that can see nearly 360 degrees. As far as insects go, dragonflies are among the fastest. Some species can fly up to 30 miles per hour and quickly and accurately change directions.

The video was filmed at The Spring Creek Greenway, Texas (Montgomery County Preserve, Old Riley Fuzzel Road Preserve, Pundt Park and Jesse H Jones Park). The Greenway is an important segment of the Sam Houston Trail & Wilderness Preserve, designed to connect and protect up to 12,000 acres of forest. See here for additional information.

One million UK dragonfly records!
Dragonfly atlas reaches 1,000,000 records
March 2013. The British Dragonfly Society (BDS) now has more than one million records of dragonflies in the UK! This stunning and remarkable achievement has been reached after a co-ordinated recording effort fuelled by the society’s atlas project. The project started in 2008 with the aim of mapping the complete distribution of dragonflies in Britain.
1 millionth record
During the five year survey period the total number of observations of dragonflies has almost doubled and the target of one million records has been achieved. This milestone was marked this week by a special award to Ingrid Twissell. Her record of a Ruddy Darter from Tewkesbury in Gloucestershire on 9th August 2012 was the one millionth entry to the BDS database. She was presented with a signed Richard Lewington print of a Ruddy Darter at the British Dragonfly Society’s annual Recorders’ Conference. This milestone in recording also coincides with the 30th anniversary of the BDS.
Scotland and Wales
Even more impressive than reaching the target of one million records has been the extent of coverage for the new atlas, particularly in Scotland and Wales. Here potential dragonfly habitat in virtually all under-recorded areas has been surveyed for records. This has only been possible through the dedicated efforts of a small team of volunteers coordinated by the British Dragonfly Society’s Dragonfly Recorder Network. Coverage has also been aided by recorders arranging dragonfly recording holidays to more remote parts of the British Isles. As a result, the atlas to be published later this year will provide a comprehensive picture of the current status of these fascinating insects and allow future changes to be monitored.
The British Dragonfly Society (BDS) started work on the new Atlas in 2008 when the database held 530,000 records. This was a good starting point, but coverage of Britain was patchy and a key aim was to achieve full coverage. As each year’s records were reviewed it was possible to identify areas still requiring more work by means of colour coded maps. These were used to encourage volunteer recorders to target the poorly recorded areas. This approach was very successful and at the start of the final year of recording (2012) only 14% of the 10km squares in the country did not have a recent dragonfly record and many of these did not contain suitable habitat, being rocky coasts or mountainous. The final tally of blank squares awaits the final analysis of records, but it is known to have reduced to below 8%.
Help from birders
Over recent years, bird-watchers have become increasingly interested in dragonflies and this has also helped the atlas project. Responding to this interest, the British Trust for Ornithology worked in partnership with the BDS in 2011 to add dragonfly recording to its Garden Birdwatch scheme. The following year dragonflies were also added to Birdtrack and these two systems now contribute thousands of sightings each year.
