It's arrogant to assume that these species are "natural".

Aedes aegypti did not exist at all in Fresno, for example, until 2013.

These species of insects were introduced to these ecosystems. By humans. The diseases (for example, Zika) being spread now are the consequences of us introducing these mosquitoes in the first place.

That mosquito species probably spent more time in Cali than humans have spent on this planet... Let's be a bit more open/honest about the bigger (4 billion year) picture here.
