Acrobatic insect sex in an Oakland County osprey nest!

The date: July 12, 2013. It was mid-morning; the time will become significant as you read on.
data to be gathered will enhance our understanding of the habits and migratory travels of
osprey, amazing fish-eating raptors that dive into the water to catch their prey.
the camera's shutter button I noticed a blur of movement; and then forgot about it. Back home I became intrigued by the mystery object ( enlarged below) and quickly discovered I had captured
an image of a pair of mating dragonflies. That in itself was kind of neat, but after positive ID
was made by a friend with a passion for and great knowledge of insects, especially dragonflies,
the story became more intriguing. I had captured an image of Halloween Pennants mating.
She had long hoped to even photograph one. She was thrilled that I captured them in their
sexual acrobatics perched on a stick in an active osprey nest. But there is more to this tale ----
wings with black bands and the fact that when perched on a stick they sway in the wind like a pennant. The species is a year round resident of Florida with Michigan and Ontario being
their northern range. But it is the mating habits and natural habitat that caught my attention.
Published research shows that " Sexual activity normally occurs between 8 and 10:30 am and males will normally wait for for females to come to them around the edges of ponds."
My pair was right on time and in the perfect wetland habitat to carry on the species!
The female is lured into the male's habitat by his flight pattern. They then begin the mating
process. The male grasps the female by the head with clasping hooks at the end of his abdomen.
So connected they fly together to find the perfect location practicing this lock-and-key technique with the male on top. According to the University of Michigan's Animal Diversity Web:
the female in back.The female bends her abdomen to reach the male's abdomen.
This is when the mating chain becomes the mating wheel.
After this, the male and female reproductive organs separate but
The female lays her eggs in dead vegetation in the water.
She descends into the water, with the male still attached and breathes via
a protective coat of air which is trapped by the fine hairs on both groups of legs."
As a naturalist I look at the image my lens captured and I do not see what entomologists call a "mating wheel". I see a heart. Take a look! Be it love or lust in the osprey nest the lucky photographic capture of these dragonflies mating next to the osprey will long be remembered.
