To answer an e-mail, yes, you can use the printed wing technique for making fly wings. Also as thorax cover, wing bids etc. It works especially well for sedges ( Caddis). Of course you need to find the wing templates and the right colours.
Here are some wing templates from my large collection, too many to post here! ( I mainly used these for making my own brass wing burners and cutters, but you can resize and colour them as desired using a graphics program. You can also copy actual fly wings from various pictures of course). These are fruit fly wings
You can find plenty of useful templates here;

And of course you can draw and copy your own.
The technique is useful, but limited of course. It would not be a good idea to put paper wings on every fly!
Once such paper wings, ( or thorax covers etc) are treated with UHU or similar stuff, they are quite durable and lifelike. One may also use different papers to print them on.
