Insects are strange, wondrous beings. Butterflies can see parts of the light spectrum that are invisible to human eyes and use these ultraviolet patterns to find their way to tasty plants. Moths use the Earth’s magnetic field to orient themselves on journeys of hundreds of miles. Bees waggle their butts to tell their hive-mates where to find a juicy stash of nectar. Insects live in our world—or humans live in theirs—yet we inhabit completely different sensory universes.
But just as we are starting to understand insect senses, something is shifting in the way we treat these creatures. Insect farming is booming in a major way. By one estimate, between 1 trillion and 1.2 trillion insects are raised on farms each year as companies race to find a high-protein, low-carbon way to feed animals and humans. In terms of sheer numbers of animals impacted, this is a transformation of a speed and scale that we’ve never seen before.
The researchers tested tomato plants and tobacco plants by depriving them of water and by cutting their stems and then recording their response with a microphone placed ten centimeters away.
In both cases, they found the plants began to emit ultrasonic sounds between 20 and 100 kilohertz, which they believed could convey their distress to other plants and organisms in the immediate vicinity.
When a tomato plant’s stem was cut, the researchers found it emitted 25 ultrasonic distress sounds over the course of an hour, according to Live Science.
Tobacco plants sent out 15 distress sounds when their stems were cut.
When the researchers deprived each plant of water, the tomato plants emitted even more distress sounds, 35 in one hour, while the tobacco plants made 11.
Last year, another study found that some plants registered ‘pain’ after having their leaves plucked or even touched, which caused the release of a foul tasting chemical across their leaves, believed to ward off insects.
Cochineal Red: How Bugs Created One of the World’s Most Expensive Colors.
Food for Thought: You’re Eating Bugs!
Not limited to clothing, cochineal (or carmine, as it’s also called) is used to give alcoholic beverages, cosmetics, shampoo and pharmaceuticals a bright red color.
It’s also used in food. In 2012, cochineal made headlines when Starbucks faced a public relations furor. Vegetarians and others who didn’t like the idea of eating bugs learned that the source of the red color in popular food items such as their Red Velvet Whoopie Pie and Strawberries and Crème Frappuccino contained insect guts. But the U.S. Food and Drug Administration has tested and approved cochineal as a food coloring.
To make this more appealing to consumers, it's often listed by other designations. So the next time you’re picking up something at the store, watch out for these ingredients, which are all other names for cochineal or carmine: E120, carminic acid, crimson lake or natural red 4 — because, really, what’s more natural than bugs?

People eat bugs all the time if they eat something with red food colouring in it.
Screws with the Vegetarians when you educate them on Cochineal Bugs.
