twosees: I read your post. I'm sorry you are stuck, I know how frustrating that can be. If I may suggest: I have those bugs and as I remember I didn't recall any specific flower that they came out to. Early in my game I was desperate for money, so I sat glued to my seat, peering at the screen, net ready and caught bugs like crazy. Those dragonflies are fast, if you don't see them come in, then realize that they are perched on a plant, swing and miss you probably missed the glassy one, he blends in so well. My best and least costly suggestion is to set aside some time and wait for them. Make sure you're growing plants that have lots of blooms. I haven't done much mutating at all, my main focus has been creating species. I have purchased two extinct seeds though. Generally I'll only buy an extinct seed when I have never seen anything like it. I'm up to 202 species.
Well I hope all of this chatter helps.
