Though scientists have long known that insects practiced hematophagy at least some 100 million years ago, the evidence had been circumstantial: fossilized mosquitoes had been found with long proboscises â the tubes that females use to dip into an animalâs veins â in a morphological indication that the species fed on blood. Just four described insect fossils offer evidence of blood feeding more direct than morphological clues, including a 95-million-year-old sand fly from Myanmar, which had parasites in its gut that associated it with blood feeding. |
