A lunchtime visit to Milton Country Park on the northern periphery of Cambridge this week to look for dragonflies turned out to be an hour well spent. For the first 10 minutes they were conspicuous by their absence but then a brown hawker appeared over a small pond, very distinctive with it’s rufous wings shimmering in the sunlight. I tried to photograph it in flight but it proved beyond my talents. Even though there were three or four whizzing around the pond at any one time I moved to a place under a tree which was overhanging the water and knelt down and waited. Within a couple of minutes a female brown hawker alighted on a log floating in the water and started ovipositing:
She seemed to be completely unfazed by my presence and busily worked her way along the log probing below and above the waterline for a suitable crevice to secrete her eggs.
She was there for around 10-15 minutes in total and every so often she took off but seemed to always to return either to her log or to a spot on the pond bank 5-6 feet from me. Even when my friend, Joe, came to see she still went about her business taking little notice of us.
She eventually departed along with all the other hawkers so we strolled along to a different location which was a wooden jetty protruding into another of the lakes. It’s surrounded all the way by dense rushes and has previously been a good place to see dragons. And that didn’t let us down either. We saw only two species, a pair of blue tailed damselfy and numerous common darters. All males. The males of this species are easily distinguished from the female as they are a glorious red and gold compared to the less vibrant green of the female.
The male of the species…
…and the lady:
There were several male common darters perched along the wooden jetty (the female above was snapped in Histon a couple of weeks ago), they were also happy to let us get up close and would occasionally dart away suddenly to chase a prey insect before returning to the same spot.
When I was out for a stroll with my friend, David, who’s a bit of a dragonfly expert, last weekend, we found a dead migrant hawker dragonfly. We were marvelling at the complexity of the compound eye and he told me that a chap in the States had counted the facets in the eye of an American species, and apparently he got up to around 28000! He must have had a string of long winter evenings to fill. But dragonflies are amazing creatures and I can see how they inspired him to want to do it.
I also took a couple of nice bird photo’s on this trip but I’ll save those until next time.
