Results of Fourth Annual Dragonfly Count

Howard County, Maryland

July 25, 2009

 

The weather was perfect for this year's dragonfly count - sunny, upper 80's and light winds. Our weather timing was perfect, too. Thunderstorms started two hours after the count ended!

Thirty-two people participated, including fifteen who were new to the dragonfly count. Six of the newcomers were volunteering as part of President Obama's "Summer of Service Program".

We tallied 44 species of odonates comprising 9200 individuals.

Some of the better finds were Slender Bluet (which set a new late date), Swamp Spreadwing, Swamp Darner, and Swift River Cruiser.

Two normally common species were incredibly abundant this year: Citrine Forktail with an estimated 4000 individuals and Eastern Amberwing with an estimated 2200 individuals.
