Weight is the same flying or not. When the butterfly is flying the wind pressure exurted from the flapping wings will be the same as the weight displaced from the butterfly sitting on the bottom. Mythbusters on the discovery channel just covered this I believe with pigeons in a semi trailer. Now go finish your homework.
Not to get off track but the Mythbusters, while one of my favorite shows, has some of the shoddiest (poorest) science and engineering I've ever seen and they regularly get it wrong!
