Social insects like bees demonstrate a remarkable range of behaviors, from working together to build structurally complex nests (complete with built-in climate control) to the pragmatic division of labor within their communities. Biologists have traditionally viewed these behaviors as pre-programmed responses that evolved over generations in response to external factors. But two papers last week reported results indicating that social learning might also play a role.

The first, published in the journal PLoS Biology, demonstrated that bumblebees could learn to solve simple puzzles by watching more experienced peers. The second, published in the journal Science, reported evidence for similar social learning in how honeybees learn to perform their trademark “waggle dance” to tell other bees in their colony where to find food or other resources. Taken together, both studies add to a growing body of evidence of a kind of “culture” among social insects like bees.

“Culture can be broadly defined as behaviors that are acquired through social learning and are maintained in a population over time, and essentially serves as a ‘second form of inheritance,’ but most studies have been conducted on species with relatively large brains: primates, cetaceans, and passerine birds,” said co-author Alice Bridges, a graduate student at Queen Mary University of London who works in the lab of co-author Lars Chittka. “I wanted to study bumblebees in particular because they are perfect models for social learning experiments. They have previously been shown to be able to learn really complex, novel, non-natural behaviors such as string-pulling both individually and socially.”

Watch these glassy-winged sharpshooters fling pee bubbles with anal catapult

Insects called glassy-wing sharpshooters have an “anal stylus” capable of flicking pee droplets at very high speeds.

The glassy-winged sharpshooter drinks huge amounts of water and thus pees frequently, expelling as much as 300 times its own body weight in urine every day. Rather than producing a steady stream of urine, sharpshooters form drops of urine at the anus and then catapult those drops away from their bodies at remarkable speeds, boasting accelerations 10 times faster than a Lamborghini. Georgia Tech scientists have determined that the insect uses this unusual “superpropulsion” mechanism to conserve energy, according to a new paper published in the journal Nature Communications.

A type of leafhopper, the glassy-winged sharpshooter (Homalodisca vitripennis) is technically an agricultural pest, the bane of California winemakers in particular since the 1990s. It feeds on many plant species (including grapes), piercing a plant’s xylem (which transports water from the roots to stems and leaves) with its needle-like mouth to suck out the sap. The insects consume a lot of sap, and their frequent urination consumes a lot of energy in turn, because of their small size and the sap’s viscosity and negative surface tension (it naturally gets sucked inward). But the sap is about 95 percent water, so there’s not much nutritional content to fuel all that peeing.

“If you were only drinking diet lemonade, and that was your entire diet, then you really wouldn’t want to waste energy in any part of your biological process,” co-author Saad Bhamla of Georgia Tech told New Scientist. “That’s sort of how it is for this tiny organism.”

Nearly 17 percent, or 22.5 million square kilometers, of the world’s land now falls within protected areas. Countries have established laws that safeguard these parcels of land—or in some cases, aquatic areas—to ensure that the natural ecosystems and their respective species and functions remain in good health. Creating protected areas has clearly helped some species, like the Asian elephant, survive.

But protected areas around the globe—at least as they stood in 2019—are failing to account for some of the world’s smallest, most vulnerable, and most fundamentally icky denizens: insects. New research sheds light on this issue, suggesting more than three-quarters of known insect species are not adequately protected by current dedicated conservation areas.

According to Shawan Chowdhury, a conservation biologist at the German Centre for Integrative Biodiversity Research and one of the paper’s authors, there are also likely many more species of creepy crawlies we don’t know about and that are likely also being failed by existing protected areas.

Mosquitos are the bane of many people’s existence, especially since their bites aren’t just annoyingly itchy; they can also spread potentially deadly parasitic diseases. Even the larvae of certain species can be formidable. While most mosquito larvae feed on algae or bacteria and similar microorganisms, some predatory species feed on other insects—including the larvae of other mosquitos. A team of scientists has captured the unique attack methods of these cannibalistic predators on high-speed video, revealing how they capture their prey with lightning-fast strikes, according to a recent study published in the journal Annals of the Entomological Society of America.

Co-author Robert Hancock, a biologist at the Metropolitan State University of Denver, became fascinated by predatory mosquito larvae when he first watched them strike their prey under a microscope during an undergraduate entomology class in college. He was impressed by the sheer speed of the attacks: “The only thing we saw was a blur of action,” he recalled. Scientists have long studied these larvae because they are so efficient at controlling the populations of other mosquito species. Just one predatory larva can devour as many as 5,000 prey larvae before reaching adulthood.

Hancock first attempted to capture the striking behavior of the larvae on 16-millimeter film by jerry-rigging a setup with a microscope and camera back in the 1990s—a process he said resulted in a lot of wasted film, given the blistering speed of the strikes. Now as a college professor, he was able to exploit all the advances in video and microscope technology that have been made since his undergraduate years to learn more about the biomechanics involved.

Online retailers are offering rare, endangered bugs

Image of a website that has a specific category for selling rare insects.

When a rare species is a product.

Alive or dead, rare or mundane, bugs are weirdly easy to find for sale online. However, in some cases, the insects or spiders sold through the various e-commerce sites, both niche and large-scale, may be of dubious provenance. Some may be bred and reared in sustainable programs. Others might be taken from wild populations that are at risk, according to new research out of Cornell University that was published last week.

“It’s not always clear… if they’re sustainable or not,” John Losey, a Cornell entomology professor and one of the paper’s authors, told Ars. “There are sites out there that are definitely not providing documentation that what they’re selling is being done sustainably.”

According to Losey, some websites will provide no documentation or proof showing that a rare pinned butterfly specimen or pet tarantula was collected in a way that doesn’t pose a risk for wild populations. Some of them could very well have been reared in a sustainable program, Losey said—there’s just no way to tell.

“Evolution can occur really, really rapidly”

When we think of evolution, we often think of slow, gradual changes made over millions of years. However, new research suggests that the process could be happening quite quickly, driving major changes over the course of a single year in response to seasonal changes.

The paper describing that research was released last week and studies evolution in fruit flies over around 10 generations, with each generation of flies spanning less than a dozen days. While fruit flies are notoriously short-lived, and the distance between their generations is tiny, evolution could be happening quicker than previously anticipated even in longer-lived organisms, according to Seth Rudman, assistant professor in the school of biological sciences at Washington State University and one of the authors of the paper.

“Over the last few decades there has been a growing appreciation that evolution can occur fairly rapidly,” he told Ars.

Robber flies are aerodynamic acrobats, able to spot their prey, dodge around obstacles, and capture smaller insects at high speeds in midflights. Scientists have taken a closer look at how robber flies manage this amazing feat despite having brains on par with a single grain of sand. According to a new paper published in the Journal of Experimental Biology, the flies combine two distinct feedback-based navigation strategies: one that involves intercepting the prey when the view is clear, and another that allows the flies to swerve around any obstacles in their flight path.

One of the challenges in robotics is how to design robots that can navigate cluttered environments—something humans and other animals manage to do instinctively every day. Per the authors, many robotic systems rely upon a kind of path-planning: using sound (sonar) or lasers to send out signals and then detecting the reflections. That data can then be used to build a distance map of the surroundings.

But compared to using simple visual cues (i.e., “reactive methods”), path-planning is a costly approach in terms of energy use. Humans and other animals don’t require elaborate maps or specific knowledge about a target’s location, speed, and other details. We simply react to any relevant stimuli in our environment in real time. Devising navigational behavioral algorithms based on biological systems is thus of great interest to roboticists.

Nikon Small World microscopy contest 2021: A few of our favorite images

Microscopy is essential to many areas of science. We use it to look at everything from the small devices we fabricate to the tiny structures inside cells. And microscopy wouldn’t function without input from many areas of science. Chemistry helps with stains, dyes, and sample preparation. Physics determines what’s possible with different forms of optics. And fields like biology and geology tell us which samples can give us valuable information. Combined, these tools give us a nearly infinite suite of options for looking at the world of the small.

With the right choices among those options, a microscope can do far more than just advance science; it can create objects of art. Each year, when Nikon releases the results of its annual microscopy competition, we struggle for new superlatives to describe the images. This year is no exception. So rather than struggling with words, we’ll get straight to the images.

The rock. We tend to think of microscopes as tools that examine living matter, revealing details that are critical to understanding cells and the organisms built from them. But chemicals and minerals also have features that aren’t always visible to the naked eye and can be critical to their behavior as well. We’ve always loved close-ups of crystals and rocks, and this year’s collection of images contains a surfeit of them.

Evolutionary chaos as butterflies, wasps, and viruses have a three-way war

Image of a moth

We’re currently watching—often in horror—what happens as a virus and its hosts engage in an evolutionary arms race. Measures to limit infectivity and enhance immunity are selecting for viral strains that spread more readily and avoid at least some of the immune response. All of that is easily explained through evolutionary theory and has been modeled mathematically.

But not all evolutionary interactions are so neat and binary. Thursday’s edition of Science included a description of a three-way fight between butterflies, the wasps that parasitize them, and the viruses that can infect both species. To call the interactions that have ensued “complicated” is a significant understatement.

Meet the combatants

One of the groups involved is the Lepidoptera, the butterflies and moths. They are seemingly the victims in this story because, like any other species, they can be infected by viruses. Many of these viral infections can be fatal, although some kill the animal quickly, and others take their time. Since they often strike during the larval/caterpillar stages, the viruses need other hosts to transfer the viruses to other victims.

MIT’s insect-sized drones are built to survive collisions

Insects are a lot of things – but fragile they’re not. Sure, most can’t withstand the full force of a human foot, but for their size, they’re evolve to be extremely rugged and resilient. Insect-sized technology, on the other hand, is general another story.

That’s certainly been the historic case with scaled-down drones. The components, in particular, tend to become more fragile the more you shrunk them. In particular, motors both lose efficiency and weaken the smaller they get.

Earlier models from the MIT lab have relied on rigid ceramic-based materials. They did the job in terms of getting the robot airborne, but as the lab notes, “foraging bumblebees endure a collision about once every second.” In other words, if you’re going to build something this small, you need to ensure that it doesn’t break down the first time it comes into contact with something.

“The challenge of building small aerial robots is immense,” says MIT Assistant Professor Kevin Yufeng Chen.

New drone models, which the lab describes as resembling, “a cassette tape with wings,” are built with soft actuators, made from carbon nanotube-coated rubber cylinders. The actuators elongate when electricity is applied at a rate up to 500 times a second. Doing this causes the wings to beat and the drones to take flight.

The drones are extremely light weight, as well, coming in at around 0.6 grams – basically as much as a big bumble bee. There are still limitations to these early models. Namely, the system currently requires them to be hardwired to deliver the necessary charge – as seen in the below gif. It can be a bit of a mess. Other modifications are being made, as well, including a more nature-inspired dragonfly shape being used for newer prototypes.

Should such the lab be able to to produce such a robot untethered with imaging capabilities and a decent sized battery, the potential applications are immense for the tiny drones. You’ve got everything from simple inspections currently being handled by larger models to pollination and search and rescue.
