In brief: Sandflies

The mosquito does not carry leishmaniasis the organism lives in the gut of the sandfly.

In brief: Life cycle

Apparently the sand fly's GI tract provides the perfect environment for the parasite to develop through it's life cycle.
Immature forms of the parasite are ingested by the sand fly when it takes a blood meal from an infected human. The parasite then develops in the sand fly mid gut. No other mosquitoes seem have what the little parasites need to develop.
