Within the last hour or two, hordes of dragonflies have started passing
through/over the Tokeland peninsula -- millions upon millions, from the
looks of it. Last time we observed this phenomenon here, two or three
years ago, Dennis Paulson enlightened Tweeters with the details of how
these particular dragonflies are born up here, migrate to Central or
South America, lay eggs and then die -- leaving their offspring to
migrate miraculously back, where those then breed and die; their
offspring head back south with no guidance from previous journeys or
parents.

Dennis, I would appreciate it if you would please tell us again what
species they are and correct/refine my recollections above. And do they
breed/live together up here in relatively close proximity to each other,
or just gather from far flung places into one large stream when it's
time to migrate?

Last time we witnessed this, it only lasted two days, with many more the
first day than the second.
