ALL HAIL THE MIGHTY FEATHERWING BEETLE!
Gotta zoom in. Okay. NOW: All hail the mighty featherwing beetle!
It’s one of the smallest insects on the planet.
It’s as small as an amoeba.
Here’s how small it is.
It would take . . . .
More than 25 featherwing beetles standing on each other’s heads to reach the length of a ladybug, end-to-end
And more than 475 to reach the length of an unsharpened #2 pencil
About 1672 to reach the top of a goldendoodle’s head
And more than 4,088 to reach the top of an average woman’s head.*
Though they be small, they be mighty. Usually, insect flight speed depends on its size. The bigger the bug, the faster the acceleration. Not so with the featherwings! They can fly with accelerations up to THREE TIMES their size.
HOW? First, their little beetle underwings look more like feathers than like the membrane paddles of most beetle wings. This helps maintain lift while reducing drag.
Next, they perform their own aerial version of a line dance. Here are the steps.
Brakes are no problem for these miniature speed demons. They use their tough outer wings, called elytra, to put the stops on that ultra momentum. Now that’s some fancy flight-work!
*As adorable and marvelous as featherwing beetles are, they’re not even the smallest insects that we know of! They dwarf some Megaphragma wasps, which are half their size.
