I've mentioned this before but, I was about 8 yrs old and learned they laid eggs on the underside of Milkweed. So I would hunt in the big field across from our house. Finally i found one with an egg on it. I "raised" it thru all its phases, chrysalis was very cool. Then let it go once it was a butterfly. The one in the pic was in neighbours front yard...I wanted so bad to take it to show our grandkids its phases it goes thru, but it's gone now. I'll keep looking lol
