Insect

Because both bats and moths are nocturnal, bats use echolocation to zero in on the insects when hunting them in the dark. A new study, however, suggests that some moths have evolved special wingtips to avoid becoming a meal.

Why do ants and other small creatures have such sharp bites? According to scientists from the University of Oregon and the Pacific Northwest National Laboratory (PNNL), the answer lies in their ability to uniformly add zinc atoms to their teeth.

After years of court battles the EPA has announced it will ban agricultural uses of chlorpyrifos, a pesticide suspected of causing health problems in children. The ban comes into effect in six months, with a further review of non-food uses to follow.

Our sense of smell seems to be the least understood. To help shed some light on the system, researchers at Rockefeller University have taken the first cryo-electron microscope images of an olfactory receptor at work in the simple system of an insect.

No matter what humans come up with, chances are nature has already done a better job. Now researchers have discovered the latest example – beetles naturally lubricate their knees with a strange substance that works better than Teflon.

UC Berkeley engineers have created an insect robot that can scamper along quickly and turn on a dime – perhaps literally. The bot owes its fancy footwork to… well, its fancy feet, using varying voltages to alternate stickiness and make sharp turns.

Amber is amazing at preserving insects and small creatures, but now it might have some competition – fossilized feces. A hapless beetle has become the first species discovered and described after being preserved in poo for 230 million years.

One of nature’s most intriguing horror stories is that of the fungus that “zombifies” ants to spread its spores. Now, researchers have discovered the oldest known example of this kind of parasite at work, preserved in ancient amber.

Although we've already heard about plants that mimic the smell of rotten meat in order to attract scavengers, botanists have now discovered that a certain plant focuses that concept – it mimics the smell of dead beetles, to draw in one type of fly.

The first thing many of us might wish for is eternal youth, but there’s always a catch. Now, scientists have discovered a version of this story playing out in ant nests, as parasites drastically extend the lifespan of worker ants – at a terrible cost.

New findings are indicating a commonly used herbicide appears to weaken the immune systems of insects. One mosquito experiment suggests the chemical can amplify insect susceptibility to parasitic infection, possibly increasing malaria transmission.

Scientists have discovered a fascinating new example of impressive teamwork among army ants, in which the insects join their bodies together to form scaffolds that stop nest mates from tumbling down steep terrain.
