Texas, USA November 2007 By Stephen Burch, England Introduction During these five days, I became increasingly aware of insects as well as birds, with colourful butterflies particularly obvious in places like Santa Ana NWR. However, dragonflies are my main interest in the insect world, so I sometimes turned my attention and the camera lens onto them, instead of birds. Maybe because of the warm conditions, some dragonflies were on the wing almost all the time, even early morning and in cloudy as well as sunny conditions. I was certainly surprised by the numbers and variety of species so late in the year. During the trip, I bought "Dragonflies through Binoculars" by Sidney Dunkle, from the Sabal Palm visitor centre. This covers all dragonflies seen in the USA, but none of the damselflies. The illustrations are all rather small photos - not nearly as good as the meticulous drawings by Richard Lewington in his recent UK & European guides, but they were adequate enough to identify most the species I managed to photo. For the ID of the others, I have benefited from help from various Internet correspondents - see acknowledgments section at the end of this page. There was a larger and more expensive tomb on just the dragonflies (and presumably damselflies) of Texas, but I didn't get it - too heavy for the flight back! Looking through "Dragonflies through Binoculars", I was surprised how few of the USA species occur in Texas! Of these, I reckon I must have found, and photographed, a good fraction of them. There are various good websites for USA dragonflies, most notably the excellent Odonta Central run by John Abbott. Photos Unlike virtually all the pictures in "Dragonflies through Binoculars", none of those given below were artificially 'posed'! Santa Ana 11 November
So this is probably by far the rarest wildlife species I saw on this trip!
At Santa Ana, there were also several dragonfly species, mainly seen along the trails. These included the widespread Common Green Darner (rather like a Lesser Emperor), the localised Band-winged Dragonlet and more widespread Eastern Pondhawks:

Atascosta 13 November Unfortunately, the weather during my visit here was somewhat mixed, with much cloud and even a few spots of rain to start with. I spent some time on the viewing platform waiting for conditions to improve for photography, which they eventually did, to an extent. However, when warmer, flight shots were impossible as the dragonflies just belted around much faster! The track back from the pond to the car was also good with settled Marl Pennant, and Variegated Meadowhawk.
Sabal Palm 14
November I also took several pics of a small dragonfly, which has turned out to be a notable find - the scarce and very localised (in the USA) Three-striped Dasher. Many thanks to John Abbott for his help with identifying this. Although the pic below isn't brilliant, it is definitely worth showing - certainly the rarest dragonfly species of the trip. I took following pics, which included some females which were more difficult to identify.

Note that there was not 100% agreement amongst the above in all cases! Nevertheless, I am now reasonably confident that the IDs on this web page are correct! I would of course be happy to hear from anyone who disagrees... |
