Overview of the 2006 Dragonfly Season

March 4, 2007 at 10:17 am (Uncategorized)

I was able to find twenty-seven new species to add to my New York life list this year. Fourteen of these were new county/species records! This brings the total count of new county/species records for Chautauqua and Cattaraugus counties up to thirty. Several of this year’s records were notable. The Double-striped Bluet (Enallagma basidens) has made its first appearance in western New York. It has been found further east, and its expected expansion into our area has now been confirmed. The Midland Clubtail (Gomphus fraternus), a species of interest for the New York survey, was found with healthy populations at two locations in our river system. The Blue-tipped Dancer, a species of interest found last year, was found again in abundant numbers around the major rivers and streams. In some locations it was the most populous damselfly.
I had some personal goals for this season that included finding more spreadwings and clubtails. I was also interested in looking for some of our bog species. Finally I was hopeful that this year I would be able to locate the American Rubyspot. I did not have as much luck as I would have wanted on the spreadwing front. I was able to find two new species. One of these, the Spotted Spreadwing, was only found once in Erie County.
I did much better with the Clubtails adding five to my list for a total of seven. This was partially due to my increase in survey locations on rivers and creeks. To further increase this number next year I will be adding the Allegany River to my list of survey sites, and I will attempt to raise dragonfly nymphs to find some of the more elusive species. I know of at least one species that I was not able to net this season.

The bog species was also a success story for me. I was most interested in find the Ebony & Ringed Boghaunters and the Elfin Skimmer. While I did not find these, I did find the American & Rack-tailed Emerald, several whitefaces, and some Darners I was not able to net. My bog surveying was mostly done at the Allenburg Bog. I think that the darners were not breeding at the bog, but at Waterman’s Swamp located a few minutes walk away. The darners I suspect I may have seen include both the Comet Darner and the Splatterdock Darner! I will be back net year 🙂

My rubyspot dreams fell victim to the September curse of school. It seems every year I am more determined to keep surveying into September and October only to have a tough class to deal with. There is always next year though!
