Why Are Moths Attracted To Lights?

For many years it was thought the moon did have something to do with the attraction of moths to light. The so-called light-compass theory held that moths used the moon as a navigational beacon. By keeping it at a constant angle to their direction of travel, they were supposedly able to fly in a straight line. The trouble (for the moths) came when they made their sightings on a close-up light source like a candle flame. Instead of heading in a straight line, they flew around the flame in an ever-narrowing spiral until finally, phhhht, moth flambé.

But this theory had more holes in it than a moth-eaten sweater. The main problem was that moths simply don’t fly around lights in spirals. This was shown by an ingenious bug researcher named Henry Hsiao. He tethered moths to little styrofoam boats in a tiny artificial pond — I love guys like this — and tracked their flight as they headed toward a light source. He found the moths flew more or less straight at the light until they got up close, at which point they veered off and circled around it at a more or less constant distance. They seldom actually touched the light.

A number of other theories have also been discredited. Some claim that, to the moth, bright lights mean open space and open space means safety. But moths are nocturnal, and the night sky has no light sources anywhere near as bright as a porch light. Besides, why should the moth feel compelled to fly around the light in circles? Others argue that moths associate light with warmth. Yet ultraviolet lamps, which are much cooler than incandescent bulbs, attract more moths.

Henry Hsiao to the rescue. He said moths exhibit two kinds of behavior. When they’re distant from a light source (they’re drawn to light from as far as 200 feet away), they make a beeline straight toward it. Why, nobody knows. Maybe they’ve tumbled to the fact that lights mean people, and people mean: Wool sweaters! On an even more basic level, a light means: Other moths! Par-ty!

However, when the moths get close to the light, a different kind of behavior takes over. Instead of being attracted to the light, the moth is actually trying to avoid the light. When you think about it, this is only natural. To a creature of the night like a moth, daylight and by extension any bright light means danger. The moth doesn’t fly directly away from the light due to a peculiarity of vision called a Mach band. A Mach band, which apparently is common to all sighted creatures, is the region surrounding a bright light that seems darker than any other part of the sky.

Hsiao conjectured that the moth’s atom-sized brain figures the darkest part of the sky is safest. So it circles the light in the Mach band region, usually at a radius of about one foot, depending on the species. Eventually either its momentum carries it away or it finds a dark corner to hole up in.

In short, moths like some light but not too much — just like other creatures I could name. Nobody wants to get burned, naturally, but at some point in our lives, aren’t we all attracted to those bright porch lights?

Why Doesn’t Honey Spoil?

 

Compliments of Jonus Luster:

For something to spoil there has to be something to spoil it. Honey is almost unique among organic compounds in that it constitutes a “perfect storm” or attributes against spoilage:

Most honey is a supersaturated, the rest is a saturated solution of sugar. Sugar acts hygroscopic, that means it attracts water. Bacteria and some other microorganisms that come in contact with this solution are being desiccated (water is drawn from them into the solution) and explode (ok, ok, they kind of just shrivel, but I like the idea of them blowing up) and die.

This supersaturation of sugar also inhibits the growth of yeast and other fungal spores.

Its pH is 3.26 to 4.48, a killing field for bacteria. Combined with the above-mentioned supersaturation you have both a pH that weakens bacterial walls and a hygroscopic environment. Them bacters don’t stand no chance.

And if all that isn’t enough, bees process honey by means of an enzyme called glucose oxydase which modifies sugar into gluconic acid ( D-glucono-δ-lactone, a contributor to the above-mentioned pH) and hydrogen peroxide. You might know glucose oxidase from something else: it used to be called “Penicillin A” and is now known as Notatin. Poor bacteria, eh?

This is, by the way, why you should never leave a jar of honey standing open. The supersaturated sugar solution will absorb moisture from the air and gradually become weaker, losing its anti-bacterial properties.

One last warning: honey is, as we discover above, rather safe. It does, however, sometimes contain inactive spores of Clostridium botulinum, the bacterium responsible for botulism. Healthy humans don’t get sick from that but infants whose intestinal tract dilutes the honey without digesting it quickly can get sick from it. There is honey that has been radiated with gamma rays to kill those spores dead for good that can be purchased for lots of money. Just wait until the kid is a year old or so and you’ll be safe.
