No, you win them from successfully completing any picture or puzzle (like a regular collection item or combining element). If you look at the "can be found list" for any picture/puzzle before you press research you will see the net listed first.

To increase your odds of winning one use luck talismans like the different horseshoes, the more powerful the better. They seem to drop more frequently from the "paid" rooms (Night Garden, Mill, Illusionists Room, Tree of Dates) than anywhere else, so playing Night Garden with a diamond horseshoe would be the best option (fireflies are easier to come by than other special items and diamond horseshoe is most powerful luck talisman/artefact available).

Once you win one it does not automatically activate, you must go into the talisman section of your inventory and activate it there like any other talisman.

That seem to drop as rewards more frequently while you have one activated, but they only last 10 minutes of real time so don't use one unless you can play for 10 minutes. Choose picture/puzzles you can complete very quickly so you can play the most amount during the 10 minutes. Blocks is a good choice as it can be completed very quickly, but any picture/puzzle will do (go for any picture in morphs mode as that is quick to complete).

I just activated one diamond horseshoe and played night garden over and over. I got the butterflies in less than 2 hours and had 9 nets left over at the end, but I can't say that is the best way to do it. Once Night Garden started working so well for me I just kept playing it and didn't bother testing how good other picture/puzzles were.
