Dunno when the mosquito eggs hatch, but it's easy to get buckets full
this time of year in Toronto.  Just be sure to pour the whole bucket
through a net once a week to get all the larvae before they mature.
Btw, the mosquitos seem to prefer grungy water to lay their eggs, so
add a bit of soil or compost or grass clippings to your bin.

There's no telling how long those eggs sat on a shelf under non-ideal
conditions. :-(  But if you leave your bucket out, you should see some
mosquito egg rafts soon.

There are some scientific supply places that sell daphnia, but it's very
expensive for a small order, shipping, etc.  

I've got white worms, vinegar eels and microworms that I'm willing to share 
with other Canadians for the cost of shipping, or in exchange for whatever.  
I will have two species of Drosophila soon, little ones (D.melanogaster) and 
big ones (D.hydei).  I've got agar, but haven't been able to get calcium 
propionate or other mold inhibitor yet.  It's cheap at the bakery suppliers, 
but the minimum quantity is 20kg ($44 Cdn), kind of an awkward thing to carry 
on the subway, not to mention enough for an army of fruit fly producers...
