larvae are an important food source for freshwater creatures; they're important not only in existing freshwater ecosystems, but also as a pioneer species getting the ball rolling in uninhabitated waters
they're also pollinators, with some plant species actually being specialized for pollination by them
bed bugs would be a more realistic nomination for their loss having zero environmental impact

the only reason they were dying out for lack of human intervention was because humans had been destroying and fragmenting their habitat
I don't really know enough about the others to give any input
