|Glimmering: The insects were found with spores|
of pollen fossils,a drop of blood and a hair from
a rodent that has also beenpreserved in amber
at the 20 million-year-old reservoir in Peru
The tiny creatures are believed to have roamed the earth alongside dinosaurs and before the ice age three million years ago.
Specimens from the period are rare and the scientists who were studying the landscape were not expecting to find the insects.
But they were amazed when they unearthed the almost perfectly preserved creepy-crawlies in northern Peru.
They were found inside small chunks or precious amber rock in a 20 million year old reservoir in Chiclayo, northern.
Honningen Klaus, who led the research team, said: 'The pieces of amber contains insects Psocoptera, Diptera, Coleoptera, Hemiptera and spiders, as well as spores and pollen fossils, and even a drop of blood and remains of hair from a mammal rodent.'
The insects were among several other examples of animals and plants fossilized in amber at the 20 million year old reservoir.
The research team was from the Meyer-Honningen Paleontological Museum in Peru.
Last year, the researchers discovered fossilised tobacco in the northern Amazon that dates back to the Pleistocene Era 2.5 million years ago.
The compact block of tobacco, about 30 square centimetres was found by the group in the Maranon river basin in northeastern Peru.
'This discovery allows us to establish that the plant dates back to the Pleistocene Era, and confirms that it originated in northern Peru,' the museum said at the time.
HOW AMBER FOSSILS FORM
Amber fossils form when insects become trapped inside the sticky sap that forms on trees.
The more they try to free themselves, the deeper inside the sap they sink.
Eventually the tree dies and over millions of years sinks into the coal bed. During this period the tree's sap hardens and forms amber stones.
The earth's surface may be eroded, or humans may excavate layers of soil, until they one day find the precious amber stone containing the insects.
Amazingly, insects, spiders, and even small lizard have been found preserved in amber. The stones may be made into expensive jewellery.
