Migrant Hawker

On Saturday morning, for want of something better to do, I wandered down to College Lake Reserve to pass a couple of hours. The weather was cool and breezy but there were still a Common Blues and the odd Small White on the wing. There were also a few dragonflies out and about including Ruddy and Common Darters basking in the weak sun and this inquisitive Migrant Darter Aeshna mixta aggressively patrolling its territory. Migrant Hawkers are great hoverer's and this male often came close as he gave me the once over, giving me a chance to grab some flight shots. I haven't quite nailed them but they are easily the best I've managed after years of trying!

Migrant Hawker

Migrant Hawker Aeshna mixta is now a familiar sight at ponds, gravel pits and reservoirs in the southern half of England but up until the 1940's was only seen as a scarce migrant, hence the name. A small population established in the south east and spread rapidly north and west and now the large resident population is regularly boosted by big influxes from the Continent. This attractive medium sized Hawker is on the wing from late August until well into October and can often be seen in large numbers flying at tree top height in woodlands and parks and often visits garden ponds along with the larger Southern Hawker. Migrant Hawkers are slightly smaller than the other Hawkers and to me appear neater, flying with the abdomen conspicuously tilted upwards. They seem very inquisitive often flying quite close to investigate, hovering motionless for a few seconds before darting away.

I spent over two hours in the hot late afternoon sunshine at College Lake Nature Reserve last Friday photographing these colourful dragonflies with some success as they were frequently perching up on reeds, the leaves of Yellow Flag Iris pseudscorus and Purple Loosestrife Lythrum salicaria which grow profusely at the waters edge. The picture below shows the diagnostic 'golf tee' marking on abdominal segment two, and the blue band at it's base.

Its always a challenge photographing Dragonflies, but because Migrant Hawkers frequently hover, one of my aims was to try and take some flight shots, but frustratingly all my efforts came to nothing with the results either slightly out of focus or much too distant. So I have had a rummage in the archives for some slightly more successful pictures, taken at the same small pool at College Lake back in September 2008.
