Your butt is glowing: the most beautiful deathtrap of the glow worm

Glowworms (found primarily in New Zealand and Australia) live on the ceilings of caves and spin threads of silk covered with a sticky mucus. They cause these strings to glow, but triggering a chemical reaction with their butts. Which is kind of awesome.
After 6 to 12 months of eating whatever they can ensnare, the larvae transform into adults, which lack mouths and never eat. Their only job, in the final few days of their lives, is to mate and create the next generation of glowing-bottomed, trap making juveniles.Finally:

“And if you give them good vibrations, they’ll, er, get the excitations. There are some tours in New Zealand, Merritt tells me, where guides will deliberately hit the water or cave walls with an inflated inner tube; in response, the field of living stars will double in brightness. Merritt can achieve the same effect in his lab by pressing a vibrating cellphone against the aquarium where his captive glowworms live. “They really brighten up intensively if they detect vibration,” he says. “I’m not sure of the function.””

Birds Beware: Of the Praying Mantis?

“Tom Vaughan, a photographer then living in Colorado’s Mancos Valley, kept a hummingbird feeder outside his house. One morning, he stepped through the portico door and noticed a black-chinned hummingbird dangling from the side of the red plastic feeder like a stray Christmas ornament.

At first, Mr. Vaughan thought he knew what was going on. “I’d previously seen a hummingbird in a state of torpor,” he said, “when it was hanging straight down by its feet, regenerating its batteries, before dropping down and flying off.”

On closer inspection, Mr. Vaughan saw that the hummingbird was hanging not by its feet but by its head. And forget about jumping its batteries: the bird was in the grip of a three-inch-long green praying mantis.

The mantis was clinging with its back legs to the rim of the feeder, holding its feathered catch in its powerful, seemingly reverent front legs, and methodically chewing through the hummingbird’s skull to get at the nutritious brain tissue within.

“It was staring at me as it fed,” Mr. Vaughan said. “Of course, I took a picture of it.” Startled by the clicking shutter, the mantis dropped its partially decapitated meal, crawled under the feeder — and began menacing two hummingbirds on the other side.”
