Can anyone speak about the capacity of mosquitoes themselves as 
pollinators? I know they spend much more time eating nectar than blood 
(which only the females do when they are breeding). I wondered if anyone 
happened to know how effective they are as pollinators.

Also, could it be helpful to consider pollinators or insects as 
a "keystone group"? Removing the occupiers of a "niche" could certainly 
effect the whole system.

 In the same spirit, I should add that many flowering plants are long-
lived perennials, many use pollinators other than bees (possibly in 
addition to bees), and many are capable of pollinating themselves or 
producing seeds asexually (and, if you want to call clonal 
growth "reproduction," a whole lot of them do that, too).  So their 
abundances cannot be expected to track bee abundances very closely.  On 
the other hand, if flowering plant abundance IS strongly correlated with 
bee abundance across space or time in your study system, it could be the 
bee populations that are tracking the plant populations.

This is what makes ecology so challenging!
