About a month ago on a morning walk to see the swallows
swooping over the Halibut Point quarry Kay and I found ourselves in a cloud of
dragonflies. Large emerald-sparked creatures tumbled and darted around us
intent on business we knew very little about. It happens that dragonflies are
another of Chris Leahy's specialties.

Chris Leahy making a
point |
We didn't actually need to snare anything to profit from an
orientation tour with Chris. He recognized Wandering Gliders, the most global of
all dragonflies, zooming around the periphery of a field at the Park entrance,
moving through on their extended migration. He suggested that our 'cloud' had
been composed of Common Green Darners, similarly massing for migration.

Green Darner on the wing |
Some of the Green Darners linger at Halibut Point, but
I'd never seen one at rest. They fly at speeds
up to 60 mph. Being green, they're hard to locate in a tree. You're much more
likely to see one take off than land. I staked out a pond to attempt a flight
photo.

Green Darner, pretty
good photo |
Focusing on a spot in their circuit, the shutter set at
1/2,000 of a second, I waited for a dragonfly to sprint through the frame at
just the right distance from my camera. After a morning's vigil I had one pretty
good photo that revealed something about the versatility of dragonfly flight.
Each wing works independently for maneuverability akin to aerial jackrabbits,
if jackrabbits could hover and dart backwards. Helicopter pilots can only
dream....

Newly emerged Green
Darner |
About this time I caught sight of a stationary Green Darner
still sporting the purple tint of a teneral, the soft-bodied muted-color phase
of a newly adult dragonfly.

Slender Spreadwing at
rest |
Close-up photographic quests revealed eye-popping
populations around the pond. In this setting my best option was to find a
comfortable perch in the muck and let them come to me, a guest in an intimate
world.

Eventually, from the comfort of home I ordered three library
books on dragonflies. It turned out that all three came from the Children's or
Young Adult sections. I pondered why.
|
Twelve-spotted
Skimmer |
Everything about a dragonfly's patterns and abilities seems
outlandish, made to order for young imaginations.
|
Yellow-legged Meadowhawk |
The names convey the whimsy of a young mind aligning
observation with fantasy.
|
Violet Dancer |
The masters of flight with translucent wings and vivid
markings draw substance from light, sparking the air.
|
Ruby or Cherry-faced
Meadowhawk |
While photographic pursuits sometimes interfere with direct
experience, the camera can magnify a dragonfly moment and retain a souvenir.
As an end in themselves the photos spurred my
search for novel sightings.
|
Spot-winged Glider |
Dragonflies have a notable place in folklore around the
world. The associations are often diabolical, perhaps alluding to their
seemingly supernatural life histories.
|
Slaty Skimmer |
Shamanic traditions link dragonflies with
transformation. A series of
metamorphoses takes them through their underwater years to their brief
fulfillment as aerial champions. At each step they set aside a tributary form
to adopt new skills and identities. This developmental pageant proceeds from a
tiny seed that evidently directs their mastery of successive environments.
|
Familiar Bluet |
Modern scientific tools have permitted insights to the
wonders of dragonfly anatomy, the interior hydraulic systems, the coordination
of 30,000 eyes within the eyes, the interactions of tissues and organs. You can
find a dynamic portrait in
The Dazzle of
Dragonflies by Forrest Mitchell and James Lasswell.

Painted Skimmer |
By taking to the skies dragonflies choreograph their
romantic fulfillment, find promising new habitats, and mesmerize their human
admirers.
