It was found on an amber piece, dated 20-30 million years.

It's a bat fly. An aggressive blood parasite which consumes blood from their victims. They inhabit from sheeps to humans where they suck their bodies living like parasites from their daily blood collecting.

Researchers, from Oregon State University, discovered this well preserved specimen on the Dominican Republic, on an amber stone, in what was then an oozing tree sap.

This is the only fossil ever found of a bat fly, and scientists say it’s an extraordinary discovery. It was also carrying malaria, further evidence of the long time that malaria has been prevalent in the New World. The genus of bat fly discovered in this research is now extinct. from here
