Cheetah-bug!

July 8, 11:30 am: Dragonflies animate the field

What: Dragonflies, possibly Halloween Pennants, their yellow and black patterned wings made my colleague exclaim, "Cheetah-bug!"
Where: Walker Open Field—iron stakes and caution tape protect the new sod. Scanning the perimeter, every stake is claimed by a dragonfly. What could be the reason? Heat? Vantage point? I must have seen 20 individuals and I wondered if they would be around at all if not for the stakes offering a feature on the landscape.
