5 Awesome Facts About the Atlas Moth

We know what you’re thinking: You’d like to torch every one of those pesky bugs buzzing around your porch light and banging into your windows.

But forget those white-winged summertime pests that come to mind. An Atlas Moth would eat them for breakfast … if it had a mouth. A native of Southeast Asia, the Atlas Moth rivals any butterfly with its beauty and grandeur, and it’s time to show this insect the respect it deserves. Why? Here are five facts about its life that we find impressive.  

1. It’s the largest moth in the world in terms of wing surface area.

Ready for this? The wingspan of a female Atlas Moth can reach up to 12 inches with a surface area of 62 square inches. Go ahead and hold up a ruler … that’s one big bug.

2. The word “Atlas” in its name has many meanings, referring to its “mapped” patterns, “titanic” size, and the snake-tipped edges of its wings.

Many see the word “Atlas” as a reference to the bold and distinct lines that form the map-like pattern found on its wings, the different colors representing different geological formations.

A second theory is based on Greek mythology. The moth is said to be named after “Atlas,” the Titan condemned by Zeus to hold the sky upon his shoulders. The reference is more about the large size of the moth than the idea that they are bearing some sort of burden.

Lastly, in China, the Cantonese name for the moth translates into “snake’s head moth,” referring to the outer tips of the wings that look very similar to the head of a snake. You can see this very clearly in just about every photo of an Atlas Moth.

While all three theories have some ground to stand on, we think the Chinese are most on-point in their observation. Those tips sure do look like snakes!

3. In Taiwan, the cocoons of Atlas Moths are used as purses.

Seriously! The cocoons are very durable and spun from broken strands of brown silk known as fagara, which local communities non-commercially collect and turn into useable products, including purses. Some vacated cocoons don’t need to be deconstructed—they can be used “as found” as small pocket-change purses by simply installing a zipper!

4. They have no mouths.

You don’t have to worry about the Atlas Moth munching on the clothes in your closet. Despite their large size, they have no mouths and don’t eat once emerging from their cocoons, relying on fat storage from their immature stages of life.  

5. Once they emerge from their cocoons, Atlas Moths have a very short lifespan.

After spending about a month in their cocoons, Atlas Moths emerge as the beautiful creatures we’ve been describing above. Unfortunately, this state is short lived as the adult moths typically die within a week or two of spreading their wings.

Japanese Artist Crafts Intricate Insects Using Bamboo

Noriyuki Saitoh

Not everyone finds insects beautiful. Some people think of them as scary, disturbing, or downright disgusting. But when Japanese artist Noriyuki Saitoh looks at a discarded cicada shell or a feeding praying mantis, he sees inspiration for his next creation.

Saitoh’s sculptures, spotted over at Colossal, are crafted by hand from bamboo. He uses the natural material to make some incredibly lifelike pieces. In one example, three wasps perch on a piece of honeycomb. In another, two mating dragonflies create a heart shape with their abdomens.

The figures he creates aren’t meant to be exact replicas of real insects. Rather, Saitoh starts his process with a list of dimensions and allows room for creativity when fine-tuning the appearances. The sense of movement and level of detail he puts into each sculpture is what makes them look so convincing.

You can browse the artist’s work on his website or follow him on social media for more stunning samples from his portfolio.

A Simple Way to Prevent Bed Bugs: Do Your Laundry While on Vacation

Bed bugs are perhaps nature's worst house guests. Not only do they, y'know, feed on your blood while you sleep, but the critters also mysteriously sneak their way into our abodes without warning, only to turn around and invite all their friends over for a slumber party. Since they won't be dissuaded by an empty fridge or an expired HBO subscription, what steps can one take to ensure their home stays free of these dreaded visitors?

For starters, do your laundry while traveling, according to a new study spotted by Gizmodo. Published in the journal Scientific Reports, its authors found that bed bugs are twice as likely to convene on and inside tote bags with dirty clothes as those containing clean clothes. They discovered this after creating a mock bedroom with cotton laundry bags—one filled with "dirty" worn clothing, the other with clean items—and observing which of the two a cageful of unleashed bed bugs preferred.

Researchers know that bed bug populations have surged around the world thanks in part to the rise of cheap air travel. They also have theorized that they're attracted to human scent, which can linger on clothing for at least a few days. Still, they didn't quite know how, exactly, the critters make the jump from the outside world and into our abodes—especially since these insects are relatively sedentary and rarely leave their feeding places. These new findings suggest that the bugs could be stowing away in attractive-smelling suitcases—which after traveling through hotels, airports, and taxis, end up right back in our bedrooms.

Since some bugs, like mosquitos, are attracted to carbon dioxide (it indicates the exhalation of a nearby animal or human—a.k.a. a food source), researchers checked to see if increases of the gas made bed bugs more or less likely to congregate on the dirty laundry bags. This ended up prompting foraging behavior, but the insects weren't any more prone to hanging out on the soiled clothing heap than they were before. 

Keeping your luggage free of bed bugs while traveling can be relatively simple, study author William Hentley, an entomologist at the UK's University of Sheffield, told Science. Since not everyone has ready access to a washer and dryer on vacation, avoid the bugs in the first place by placing your suitcase atop the metal luggage racks commonly found in hotel rooms, even if you've already given the room a precautionary sweep. (Bed bugs can't climb up smooth surfaces.) If your room is sans rack, seal your dirty clothes inside an airtight bag to keep the insects from getting a good whiff, or wrap up your entire suitcase if it's frequently been home to unwashed garments in the past.

That said, not all is lost if you arrive home from a long vacation with a bag full of well-worn outfits. Take your clothes immediately to a washer/dryer and run them through a hot cycle. That should be enough to kill invading bed bugs before they've even had the chance to learn how comfortable your couch is.
