A study by the CSIC-UMH Institute of Neurosciences uncovers how flies' flight stabilizers, the halteres, take shape. The structure is stabilized by a sophisticated cellular system that connects its two surfaces through an internal framework.

Museum collections reveal worldwide spread of butterfly disease

A study from the University of Georgia used museum specimens to track the spread of Ophryocystis elektroscirrha, a parasite affecting millions of monarchs during their annual migration. The research found evidence of infection in the Americas, Europe, Asia, Africa, and Oceania, with limited species affected.

Slingshot spiders listen to fire off ballistic webs when they hear mosquitoes within range

Researchers found that slingshot spiders can listen for approaching insects before releasing their web to catapult forward and capture prey. The spiders use sound-sensitive hairs on their legs to detect the vibrations from the insects' wings, allowing them to deploy their webs in mid-air.

Genomic dark matter solves butterfly evolutionary riddle

A team of international researchers has discovered a surprising genetic mechanism that influences the vibrant patterns on butterfly wings. An RNA molecule controls where dark pigments are made during butterfly metamorphosis, shaping the butterfly's color patterns in a way previously unforeseen.

Flying like a beetle

Scientists have unveiled that beetles' hindwings are passively deployed and retracted, leveraging the elytra to deploy and retract while flapping forces unfold the wings. This finding has potential applications in designing new microrobots that can fly in confined spaces.

From takeoff to flight, the wiring of a fly's nervous system is mapped

Researchers create detailed wiring diagram of motor circuits in fruit flies, revealing complex nerve coordination for leg and wing movements. The study advances understanding of how the central nervous system coordinates individual muscles for various behaviors.

Dragonfly wings used to study relationship between corrugated wing structure and vortex motions

The study discovered that corrugated wings exhibit larger lift than flat wings when the angle of attack is greater than 30°. The researchers analyzed the flow around a two-dimensional corrugated wing using direct numerical calculations and found a unique airflow dance set off by a distinct corrugated structure.

Research on bee virus origins uncovers buzz-worthy breakthrough

New research reveals that the Deformed wing virus DWV-A originated in Asia, contradicting previous European origins. The study found that Varroa mites transmitted the virus to European honey bees after their introduction to Asia, leading to widespread infections and colony declines.

Small-winged and lighter colored butterflies likely to be at greatest threat from climate change

Butterflies with smaller or lighter-colored wings, such as those in the Lycaenidae family, are likely to face greater threats from climate change. These species have poorer thermal buffering abilities, which could lead to dramatic declines if temperatures rise.

Electrical synapses in the neural network of insects found to have unexpected role in controlling flight power

Researchers at Mainz University and Berlin found a previously unknown function of electrical synapses in the insect neural network, governing wing movement and generating consistent flight power. The discovery reveals new concepts of information processing by the central nervous system.

Researchers build bee robot that can twist

Washington State University researchers developed a robotic bee that can fly fully in all directions, including twisting motion. The Bee++ prototype achieves six degrees of free movement and is controlled by an artificial brain that acts like an insect's brain.

Preserving pine forests by understanding beetle flight

Researchers used fluid dynamics models to study the mountain pine beetle's flight, finding that wing shape, age, and size impact thrust production. This knowledge can improve statistical confidence levels for insect dispersion studies and help preserve pine forests.

Resilient bug-sized robots keep flying even after wing damage

Researchers at MIT have created a way for tiny robots to recover from severe damage to their wings, enabling them to sustain flight performance. The development uses laser repair methods and optimized artificial muscles that can isolate defects and overcome minor damage, allowing the robot to continue flying effectively.

Parasitic mites’ biting rate may drive transmission of Deformed wing virus in honey bees

A study found that a small number of Varroa mites can infect many adult honey bees, with high-risk mites spreading pathogens through frequent host switching. This mechanism amplifies the vectorial capacity of Varroa destructor.

New hawk moth species are among the smallest ever discovered

Three new hawk moth species have been discovered in The Bahamas, measuring only about the length of a vitamin pill. Their small size is thought to be an adaptation to survive harsh weather conditions such as hurricanes and drought.
