I just tracked back the ancestors of Dizzy Damselfly until I located Paper Butterfly in it. Then I looked at the database entries for relatives and their photos. An interesting exercise, especially when there are multiple photos posted to the database. I'm guessing the trait is linked to pattern and possibly enhanced in certain color ranges. It seemed when the descendants left that range, they often didn't exhibit 'canoeing'. Not always though. It may be associated with a pattern/color, but it's expression may also be affected by growing conditions - e.g. weather and soil. It can probably be ironed out, but not easily. I set a few pods on Dizzy Damselfly and some are up. Maybe I'll see bloom someday. I don't have a lot of daylilies and only about half are tet and not everything was blooming, so even if those bees carrying around masses of pollen messed up the marked crosses there would be limited choices and nothing else exhibited the trait.
