[green lacewing vibrating] woop-woop woop-woop woop-woop woop-woop A mating call that pulses like a heartbeat.

[green lacewing vibrating] woop-woop woop-woop An alfalfa field full of potential.

In the search for green lacewing love ... ... which romances will bloom?

and which ... will wither?

Here in California’s Central Valley, this lacewing  bachelor is single and ready to mingle.

[green lacewing vibrating] woop-woop woop-woop Sure,  he’s a looker with those glassy wings  and shimmering eyes.

But it’s his vibes that really matter.

Which we can hear because scientists have amplified them.

[green lacewing vibrating] woop-woop woop-woop He shakes his abdomen to announce he’s on the market.

[green lacewing vibrating] woop-woop woop-woop His vibration travels through the plant he’s perched on.

But no one’s around to appreciate it.

He tries again on a different leaf.

[green lacewing vibrating] woop-woop [green lacewing vibrating] woop-woop woop-woop woop-woop This time, she’s feeling it.

“Will you accept this vibration?” “I will.” [green lacewing vibrating] woop-woop But even when they find each other, their songs  don’t guarantee they’re a match.

[green lacewing vibrating] woop-woop "Is she here for the right reasons?"

[green lacewing vibrating] woop-woop To find out, they enter this leafy fantasy suite.

They touch antennae and taste each other.

They’re headed for their  most intimate moment yet.

That escalated quickly!

But sometimes more than one lacewing responds  to a call, and the drama heats up.

With two ladies here, one is certainly going home.

Please take a moment to say your goodbyes.

[green lacewing vibrating] woop-woop Male and female lacewings of the same species  sing each other essentially the same romantic song.

It's encoded in their DNA.

One lacewing species sounds a bit like a purring cat.

[green lacewing vibrating] purr [green lacewing vibrating] purr Another one more like a growling stomach.

Look who’s arrived, a baby!

Yes, it is theirs.

It’s so cute!?

And so hungry.

Each lacewing larva devours hundreds  of aphids and other orchard pests each week.

It liquefies their insides and slurps them up.

That’s why gardeners and growers love these babies born of romantic vibrations.

The larva will need that energy to transform   into a beautiful adult ... ... that will put its own heart ... and vibration ... [green lacewing vibrating] woop-woop on the line.
