Scientists observed a baby white-necked jacobin hummingbird in Panama mimicking a poisonous caterpillar to deter predators, marking the first clear record of caterpillar-like mimicry in a hummingbird, which may help it survive in predator-rich tropical forests.
Researchers discovered a deep-sea squid in the Clarion-Clipperton Zone exhibiting unprecedented mimicry behavior, blending into its surroundings by imitating sea sponges or coral stalks, which may serve as a survival tactic against predators or for hunting. This finding highlights the complex adaptations of abyssal creatures and underscores the need for conservation amid threats like seabed mining.
The article explores how adopting the mindset of better or more competent individuals through mimicry can instantly improve skills and performance across various tasks, emphasizing that humans learn and excel by imitating and internalizing the behaviors and strategies of others, often surpassing perceived limits by setting higher standards than those around us.
Mimesis is an upcoming co-op horror game that uses advanced AI to mimic players' movements and voices, creating a terrifying environment where players must discern friend from foe as enemies imitate their actions and speech, adding a new level of psychological horror and mistrust.
Researchers in a tropical rainforest in China observed a male and female crab spider, Thomisus guangxicus, resembling a complete flower, potentially exhibiting cooperative mimicry. The larger female spider mimics the petals of the Hoya pandurata plant, while the male perched on top resembles the flower's pistils and stamens. This behavior may help them avoid predation and improve male survival during the mating process. The study suggests that this could be the first known case of cooperative mimicry in the world, providing insights into the remarkable mimicry and ambush skills of crab spiders.
Paleobiologist George Poinar Jr. has uncovered a rare find of a spider fossilized in resin, which he named Myrmarachne colombiana, that mimics the appearance of an ant. This discovery sheds light on the evolutionary strategy of certain spider species to deceive predators by resembling less desirable prey. The fossil, found in copal from Colombia, provides insight into the complex adaptations and behaviors of these ant-mimicking spiders, challenging previous notions about the origins of insect habits and suggesting a level of reasoning and intelligence in their mimicry.
Spiders have evolved various crafty techniques to lure in their prey, including using their looks, scent, and touch to trick unsuspecting invertebrates. Some spiders create intricate webs with thick white silk bands to attract prey, while others use bright colors and patterns to mimic flowers and dazzle insects. Certain spiders rely on scent signals or pretend to be stuck in their prey's web to lure them out, while others imitate the mating behavior of their prey's potential mate. These complex behaviors showcase the impressive and diverse ways in which spiders use lures to capture their food.
Foul-mouthed parrots at U.K.’s Lincolnshire Wildlife Park, known for their ability to swear, will undergo group therapy by being introduced to a larger group of proper parrots in the hope of curbing their cursing, as experts believe parrots easily mimic swear words due to their tone and context. The park acknowledges the risk of the bad habits rubbing off on the larger group.
Trinamool Congress leader Kalyan Banerjee was recorded mimicking Rajya Sabha Chairman and Vice-President Jagdeep Dhankhar by Congress leader Rahul Gandhi, sparking criticism from Dhankhar who called it "shameful, ridiculous, and unacceptable." The incident occurred amidst protests by the Opposition demanding a discussion on the Parliament security breach. Dhankhar expressed his disappointment at a senior leader videographing another member of a different party, stating that it was a mockery of the institution. The video clip shows Banerjee impersonating the Rajya Sabha Chairperson, while Rahul Gandhi appears to record it.
A newly discovered beetle, Austrospirachtha carrijoi, has evolved a remarkable mimicry strategy to trick termites into feeding it. The beetle grows a "puppet termite" on its back that closely resembles the termites' body segments and appendages. By begging for food from the termites, the beetle can live off termite room service once it infiltrates their nest. This mimicry is just one example of the rove beetles' mastery of mimicry, with some species even evolving to resemble army ants to feed on their eggs and young.
The survival secret of a brightly colored spider that mimics ants to deter predators is the imperfection of its impressions. The tiny jumping spider Siler collingwoodi lifts its front legs to form mock antennae while swinging its legs and jiggling its abdomen to copy an ant's gait. A new study reveals that S. collingwoodi's impersonation is far from perfect, but its imperfect performance enables the amateur performer to mimic multiple ant species and deter most of its predators.
Siler collingwoodi, a colorful jumping spider found in China and Japan, imitates certain features of multiple species of ants, but not perfectly, making it an imperfect mimic. Researchers found that this imperfection is enough to fool one of the jumping spider’s most dangerous predators. The spiders may also find another layer of protection by blending into a similarly brilliant plant in their habitat. The findings were published in iScience.
Men with higher levels of psychopathic personality traits are more likely to mimic prosocial personality traits, such as honesty and agreeableness, in order to appear more appealing to women in dating scenarios. The study found that psychopathic traits were associated with significant increases in these personality traits when men were instructed to present themselves in a way that would be most attractive to the woman in a dating profile video. However, associations between psychopathic traits and measures of mimicry were only marginal.
Scientists have discovered how the South African daisy Gorteria diffusa evolved to mimic the appearance of female flies to attract pollinators. The daisy's petals range from pale yellow to bright red-orange, some with spots that form a circle around the flower's center. The evolution of this species' variety of features was recently mapped to determine the order in which the traits evolved to culminate in such a convincing deception: it revealed color first, then random positioning, then texture. The daisy brought together existing genes, which already do other things in different parts of the plant, to make a complicated spot on the petals that deceives male flies.
