according to new research, mosquitoes that feed on blood have been around for at least 46 million years. Researchers led from the Smithsonian's National Museum of Natural History made the discovery by studying fossilized mosquitoes. Eventually, they came across one that appeared to still be filled with its final meal of blood — though that may not sound like a rare phenomenon, it is. The researchers write that such a finding has never been described before.
