Researchers have now discovered a new mozzie with blood in it, which is actually very old.

Yes! It's a fossil of a mosquito, whose abdomen was seemingly a dried blood tank. Study author Dale Greenwalt from National Museum of Natural History said that the mozzie was the one of its kind and was extremely rare.

Humans are no new target of mosquitoes. But, the researchers said that other creatures have also been their target as indicated by the blood in the 46-million-year-old female mosquito. Her puffy abdomen showed iron traces, which created a mystery which creature's blood could have been sucked.

DNA could not be traced by the team as the genetic material could only last for 3.6 million years or a bit more. An earlier research has also proven the same.

Greenwalt was of the belief that the blood could be of a bird. This is because the mozzie specimen represented a modern one from Culicidae family and the same is known to feed on feathered friends of humans.

"Having an actual blood-engorged female mosquito associated with males in the same fossil formation is hugely unlikely", stated University of California's Lynn Kimsey. He was not a part of the study.
