Bees learn new tricks from one another in world-first for insects

They may have tiny brains, but it turns out that bumblebees can not only learn to use tools by observing others, they can improvise and make the task even easier.
We knew bees were smart, but this level of brain power has never before been seen in an insect, according to a team of UK scientists writing in the journal Science.

Trillions of high-flying migratory insects cross over UK

For the first time scientists have been able to track the hordes of high-flying insects that pass across the skies of Southern England every year.
Unseen and unnoticed by humans, researchers found that 3.5 trillion bugs and butterflies annually migrate across the region.
The researchers say their mass is equivalent to 20,000 flying reindeer.

Scientists have made a rare find: a new species of fossil beetle from Antarctica.

It's the first evidence of a ground beetle found on the southernmost continent.
And Antarctic insects are themselves a rarity - the absence of biodiversity is considered a consequence of a lack of moisture, vegetation and the low temperatures.

Researchers have identified a parasitic wasp without wings preserved in 100-million-year-old amber from what is now the Hukawng Valley in Myanmar on the continent of Asia and created a new family for the specimen, called Aptenoperissidae.
The well preserved insect, named Aptenoperissus burmanicus, is now extinct. It seems to borrow parts of its anatomy from a range of other insects but belongs to no other family ever identified on Earth. It probably crawled along the ground at the base of trees trying to find other insects and a place to lay its eggs.

Student discovers extinct plague locust specimens

While organizing drawers of unidentified grasshopper specimens at the Cornell University Insect Collection (CUIC), something caught the eye of Brandon Woo '19.
Three oddly shaped dull brown specimens with extra-long wings stood out to the Cornell entomology student whose area of focus is a group of insects called orthopterans, which includes grasshoppers, locusts, crickets and katydids. Comparing the specimens' lot number to a CUIC log book, Woo learned he had uncovered Melanoplus spretus, the Rocky Mountain locust, an extinct pest that wreaked agricultural havoc 150 years ago.

Spread of bee disease 'largely manmade'

The global trade in bees is driving a pandemic that threatens hives and wild bees, UK scientists say.
A deadly bee disease has spread worldwide through imports of infected honeybees, according to genetic evidence.
Stricter controls are needed to protect bees from other emerging diseases, researchers report in Science journal.

'Extinct' fly found in Devon nature reserve

A fly thought to be extinct in the UK has been found in a Devon nature reserve.
The rhaphium pectinatum was last recorded in Britain 147 years ago in 1868 but was rediscovered in Old Sludge Beds on the outskirts of Exeter.
The fly is from the Dolichopidiae family, a group known as long-legged flies, and is usually found in tropical parts of the world.

Donut-shaped 'compass' glimpsed inside fly brain

A cluster of cells in the brain of a fly can track the animal's orientation like a compass, a study has revealed.
Fixed in place on top of a spherical treadmill, a fruit fly walked on the spot while neuroscientists peered into its brain using a microscope.

Scientists unveil secrets of insect evolution

Using genetic analysis, scientists have been able to conclusively establish that insects originated about 480 million years ago, and that they developed the ability to fly some 80 million years later, the Commonwealth of Scientific and Industrial Research Organization (CSIRO) said on Friday.

Greater wax moth 'can sense' highest recorded frequency

The greater wax moth is capable of hearing the highest recorded frequency of any animal in the natural world, researchers have discovered.
A team at Strathclyde University in Glasgow found the moth can sense sound frequencies of up to 300kHz.
