In the Leishmania life cycle, which organism takes the blood meal?

Explanation:
The blood meal is taken by the female sandfly because, in this system, only the biting sex uses blood to support egg development. This feeding behavior is what drives Leishmania transmission: the female sandfly acquires parasites from an infected mammal during a blood meal, the parasites develop inside the sandfly, and then the next time the female bites, she can transmit Promastigotes to a new mammalian host. Males do not take blood meals, and dogs or humans are hosts rather than vectors. So the organism responsible for taking the blood meal is the female sandfly.
