Killifish and Mummichogs are also significant larval predators.

Subject: Re: [NatureNS] Who are mosquito predators?
I understand that dragonflies eat the mosquito larvae. I remember that Pur=
ple Martins were formerly thought to be good for mosquito control. Subsequ=
ent studies of their eating habits indicated they ate a large number of dra=
gonflies, which would certainly not be good for keeping mosquito numbers do=
wn.

Subject: RE: re bats endangered -- good for other insectivores??
Hi all,
Hugh is quite right. The idea that insectivorous bats in North America feed=
on mosquitoes is a myth derived from a gross misunderstanding of a single =
old paper that provided the numbers of mosquitoes eaten in one night by a c=
aptive big brown bat (Eptesicus fuscus). It would normally prey on much lar=
ger insects, but made do with mosquitoes because that was all it was offere=
d. Also, it is a much larger animal than the little brown, long-eared and t=
ricolored bats in NS.
In fact the vast majority of the feeding time of insectivorous bats is spen=
t well above the zones where mosquitoes are found. Even when bats forage wi=
thin a meter or two of the forest canopy, there are no mosquitoes there bec=
ause there are no sleeping warm-blooded animals in the air-they are all dow=
n in the foliage. The bats will take a mosquito if they come across one, bu=
t to seek them out they would have to dodge and flutter through cluttered e=
nvironments under trees and shrubs, or within a foot or two of the grass on=
fields or meadows, and it wouldn't be an energetically efficient way to fo=
rage, especially for such a small protein package.
It is also wrongly believed by many that swallows and swifts eats large amo=
unts of mosquitoes, but they normally feed high in the open air, well away =
from any zone where mosquitoes would be hanging out. Mosquitoes normally re=
st on vegetation until some disturbance or signal that could mean a blood m=
eal stimulates them to take wing and seek it out.
Cheers,
Fred
