Red-necked keelback snakes possess a potent toxin derived from the toads they consume, which can cause severe harm to predators like mongooses. The snakes store these toxins in specialized nuchal glands.
This study started from a discussion with my co-author and postdoctoral researcher, Sabrina Rondeau, whose recent findings showed that these queens can survive submersion for over a week, which is extraordinary for a terrestrial insect. We wanted to understand how that's even possible.
A maggot's age and species can give essential information to forensic entomologists investigating murders. Combing through these fly larvae, investigators can potentially learn when and where a crime happened, whether the body has been moved or whether toxins were involved. For example, blowflies are among the earliest insect colonizers of corpses; they typically sniff out and lay eggs on a dead body within minutes to hours.
These caterpillars use a surprisingly complex rhythm like a secret knock to convince the ants to come fetch them. That's according to research published on February 25 in Annals of the New York Academy of Sciences, which found that caterpillars can keep a beat called double meter that has so far been identified only in a couple of primates.
London is the only place in the UK where you can find scorpions, snakes, turtles, seals, peacocks, falcons all in one city and not London zoo. Step outside and you will encounter a patchwork of writhing, buzzing, bubbling urban microclimates. Sam Davenport, the director of nature recovery at the London Wildlife Trust, emphasises the sheer variation in habitats that you find in UK cities, which creates an amazing mosaic of wildlife.

Native ants are beneficial to the environment. They will eat pest insects such as fleas and termites. They also aid in breaking down organic matter such as dead plants and animals. Native ants form distinct colonies that will battle each other, limiting their populations. They also tend to behave themselves and stay outdoors. Argentine ants tend to invade indoor spaces during hot, dry weather or after heavy rain.
What's scarier than a spider? A really big spider, of course. A newfound defensive tactic takes advantage of this idea: researchers documented spiders building giant spiderlike silhouettes on their webs to ward off predators. These decoys are an example of web decorations that some spiders are known to produce, often to prevent getting eaten, avoid bird strikes or attract prey.
On a spring day in 1694, Antonie van Leeuwenhoek - the father of microbiology - used a magnifying lens to look at a candle through the dissected eye of a dragonfly. But instead of seeing 1 candle flame, he saw hundreds of tiny flames, repeated over and over. But spoiler alert - this is not how insects see. Hi, I'm Niba, and today we're going to explore how insects really see the world.
The mirror spider can rapidly shift a patchwork of minuscule reflective plates underneath its abdomen's outer surface, altering the pattern of mirrorlike flashes. This uncommon display comes from common building blocks: Similar tilelike arrangements of plates and soft joints appear throughout the tree of life, from turtle shells to tropical fruit peels. Researchers have now compiled 100 examples of this pattern across animals, plants, microbes and viruses, which they describe in PNAS Nexus.
