Hi Muffin,

There isn't really anything you can do regarding dragonflies. They will either
come or they won't.
You might be able to fish out a few nymphs (watch out they pinch!) but you'll
never get them all.

This is one of the quandaries of pond keeping. We have invaded Mother Nature's
territory and fight as much as we want she *is* going to win in the end.

If you don't have some sort of thinning program going on your fish are
eventually going to reproduce themselves into a severe overstocking problem and
the resulting mess will be painful and deadly for all the fish.

Predators serve a purpose or we'd be neck deep in mice, mosquitoes, frogs,
insects... you name it.
(eek! feeling all creepy crawly after writing that sentence!)

Who knows there could be a dragonfly out there cruising around who is going to
eat the mosquito that was headed for you brimming with West Nile virus.

Not much, I suspect. Goldfish will continue to multiply until they
contaminate a pond and lot of koi keepers don't want fry. I have
plenty of fry to share.

That was I.
Dragonflies are supposed to be a very good control for mosquitoes and
mosquito lava.
I live in the Toronto area where West Nile is an emergent problem.
Because it is new and people do not understand how small the risks are
they are doing all sorts of silly things, like proposing bylaws to outlaw
standing water (including garden/ornamental ponds). Part of the problem
is the media who report single cases of the disease as though they were
reporting the end of the world.
Currently local health laws allow for the public health department to
check for standing water and lava, this is quite reasonable from a public
health stand point, but in one case that I have heard of they demanded
that the owner fill in his pond. I do not know the details, maybe it was
a very poorly maintained or there was some other problem with it all the
same I would prefer not to have fight to keep my pond. So any thing I can
do to keep the nasty bugs down in my pond sounds like a good idea.
I am using Aquabac, which works very well, but it would be nice to have
something a little more attractive to act as a pest control.

If you have fish, you will probably not have any mosquitoes. If you have
dragonflies, they further reduce the population. If you are still worried,
use mosquito dunks, they have a natural bacteria that kills the mosquito
larva without affecting any other critters. You can use both fish and
dunks, and the dragonflies will still come.

Dragonflies are one of my favorite subjects to research.
The US military has studied dragonflies to see how they 'work'. They are an
absolute miracle when you get right down to it.
They can buzz along at 35 miles per hour and reverse direction within a body
length. They can hover and fly backward with ease.
They actually fly in 'antiphase' as their two sets of wings operate
independently of each other in that the hind pair of wings operate on the air
before the front pair.
Their compound eyes have between 10,000 and 30,000 individual facets. Each eye
can be moved and adjusted while tracking down their prey.
Their breeding habits are downright strange but we'll leave that for another
day...
;-)

Yes, but I also remember from my child hood days, that my Snoopy
Encyclopedia told me they would also gore your tongue out. I vividly
remember Peppermint Patty running around with her hands over her mouth. I
don't care what Charlie Brown said, I keep my mouth shut when I am near my
Dragon flies.
