When we think of ferocious predators among animals we likely think of sharks and grizzly bears, big creatures with teeth. But I remember as a kid watching ladybugs on a rose bush moving through aphids like a combine through wheat. They can consume thousands in their brief life span.
Another small and notably
efficient hunter is the order Odonata – dragonflies and damselflies. I spent a day in an upstate New York marsh with a neuroethologist, a
biologist who studies how an animal’s nervous system determines its behavior. Odonata
was his specialty. His
research showed their kill rate for insects, most often mosquitoes, topped
ninety-seven percent. Eighty percent of a dragonfly’s brain is devoted to
vision, and their field of vision is 360 degrees. Like ladybugs they are harmless
to humans.
I remembered that day when reading the Louisiana poet David Middleton’s “August into
Autumn” (Time Will Tell: Collected Poems (Texas Review Press, 2025):
“It happens every year
almost the same
And always late in August
when we pause
Just long enough to see
what time has done,
Sly changes nearly
imperceptible
Moment to moment holding
us at last
While molting birds gone
quiet watch the stars
And summer moves to its
appointed end.
“The mated dragonflies,
whose months are years,
Their eggs already
floating in the reeds,
Now glide more slowly over
lake and blade,
The great blue skimmer,
eastern amber-wing
Still hunting for
mosquitoes, dusk and dawn,
But farther off as the
dense swarms grow thin
And crickets call all
night through cooling trees.”
Middleton describes the slow
change of seasons in the South, with none of the North’s drama or unambiguous demarcations.
Autumn is little different from summer here if you’re not paying attention.
Temperature changes are incremental. No gaudy red or yellow explosion among the maples
(we have few maples). We’ll see more hummingbirds here in September as they
migrate south. For a transplanted Northerner, autumn in Texas and Louisiana can
be a disappointment. In “The Dragonfly,” Louise Bogan describes the insect’s “ceaseless
movement, / Unending hunger . . .” In the poem’s final lines she is almost
clinical: “And you fall / With the other husks of summer.”
