"My Favorite Museum Exhibit" is a series of posts aimed at giving BoingBoing readers a chance to show off their favorite exhibits and specimens, preferably from museums that might go overlooked in the tourism pantheon. I'll be featuring posts in this series all week. Want to see them all? Check out the archive post. I'll update the full list there every morning.
You've seen a lot of good taxidermy this week, but nothing quite like this. Renee Mertz sent me this photo of a diorama at Vienna's Naturhistorisches Museum, which depicts a group of butterflies greedily feeding off the carcass of a dead piranha.
This is not a spot of whimsy, people. This kind of thing really does happen. In fact, you can watch a real-life example (with a less-threatening fish substituted in for the piranha) in a video taken in Alabama's Bankhead National Forest.
The good news: The butterflies are not really carnivorous, per se. The bad news: What they're actually doing is still pretty damn creepy.
It's called "puddling" or "mud-puddling". The basic idea works like this: Butterflies get most of their diet in the form of nectar. They're pollinators. But nectar doesn't have all the nutrients and minerals butterflies need to survive, so they have to dip their probosces into some other food sources, as well. Depending on the species of butterfly, those other sources can include: Mineral-rich water in a shallow mud puddle, animal poop, and (yes) carrion.
When butterflies puddle over a dead fish, though, they aren't biting off chunks. Instead, they're essentially licking the dead fish—going after salt and minerals that seep out of the dead animal as it decomposes. Bonus: Some butterflies also like to lick the sweat off of humans. And a few species of moth have been documented sucking blood and tears for living animals, including humans.
Despite Trump’s denial of climate change the the ghastly attacks on climate science and mitigation in the new proposed budget, the Carbon Bubble — which overprices hydrocarbons and the industries that rely on them, as though we’ll be burning all of them with impunity — is about to pop.
South American polka dot tree frogs are pretty cool, but Julián Faivovich and Carlos Taboada found out they are even cooler when an ultraviolet flashlight is trained on them. They fluoresce. Many animals can see beyond the spectrum visible to humans, and these frogs adapted with this trait. From the abstract: Fluorescence, the absorption of […]
A small (51 men aged 24 +/- 3 years) study published in Neuron tasked experimental subjects with practicing the ancient Greek mnemonic technique of “memory palaces” and then scanned their brains with functional magnetic resonance imaging, comparing the scans to scans from competitive “memory athletes” and also measuring their performance on memorization tasks.
The Lightning port has thus far resisted the cruel fate that befell the headphone jack, and despite rumors that it may be disappearing come iPhone 8, for the present and foreseeable future, Lightning cables are a hot commodity for iPhone users. As such, we must make do in this strange time in which long, glorified […]
All the filters in the world won’t save your smartphone pics from a shaky hand. To really step up your mobile photography game, you’ll need some kind of mount to hold it steady. You could buy a smartphone attachment for a conventional camera tripod, but who wants to carry that kind of gear everywhere they […]
The forced transition from analog to digital TV signals was probably met with relative indifference from people with Netflix subscriptions and the “I don’t even own a TV” snoots. But anyone living in the vast swaths of the country that don’t have guaranteed high-speed internet, broadcast TV is a perfectly valid (and 100% free) way […]
