Do they mate mid-air? how do they do it?
Earlier in the summer, I was watching some Cabbage Whites doing something odd -- one was actually laying on it's back on a leaf and reaching up with the tip of its (her?) abdomen. When another one landed on top and they hooked up, I caught on to what they were doing.
I was wondering because my 3 (2 females, 1 male) from yesterday was very restless today, flapping all over the cage, and it seemed like the females were trying to flip over. I just let them go about an hour ago. One female took off without bothering to stay on the butterfly bush flower my DD set her on, ther other famale was reaching for a flower with her probosis even before DD could get her on a flower cluster and drank for a long time, and the male was also pretty hungry/thirsty but took off long before the female was done.
They did have a bouquet of flowers in the cage as well as a piece of overripe melon. I know they usually don't eat/drink right away but I like to have something in the cage for them, just in case.
