Caught in the act:
Forget about the birds and the bees - the bugs were there first. A 165-million-year-old fossil depicting two copulating froghoppers was dug up by scientists in north-eastern China. The imprint of the male and female froghoppers - which are so named because they jump around on plants and shrubs like tiny frogs - is believed to be the oldest fossil showing mating insects. Scientists said the pair were in the throes of passion when they were struck dead by poisonous fumes from an erupting volcano.
