Gliding spiders
|
view preview
These tropical arachnids known as selenopid spiders (pictured above) possess the rare ability to steer themselves in the air and jump between trees - an unexpected talent for spiders, which have no history of flight.

A woolly insect
|
view preview
It is not surprising that this family of moths are commonly called woolly bears or woolly worms, as the caterpillars of many species are really very hairy. The larvae can be full of poisonous chemicals acquired from their host plants, advertising that they are bad to eat with bright colours, bad odours and unusual shapes. The adult moths have distinctive wing venation and can also be distasteful when eaten. They produce ultrasonic sounds to warn off predators and confuse bats looking for a tasty treat. There are over 10,000 species worldwide including all the tiger, footmen, wasp and lichen moths. Amazingly, the caterpillars of some species can even survive freezing. ...

Why does airplane food taste strange?
|
view preview
 If you've been fortunate enough to fly on an airplane, you've probably noticed that the food tastes a bit strange. It turns out that it's not actually because of the food itself (even if you are sitting in economy) but the reduced atmospheric pressure on board and the dry nose and mouth we get from flying, says an expert.
