I wonder if this could be an evolutionary process where a new biological species may arise. For more than over 20 years we have been around, our field lepidopterist claimed to have not seen this before. Look what we have found recently:

Can two different butterfly species mate with each other? What do you think?

These 2 species of butterfly have been found mating in our farm late evening yesterday. The male is a Cethosia cyane, while the female is the Parantica aspasia. Could this be just an accident in nature? Or can nature or its surrounding force the butterflies to change their behaviour? Possibly, studies have found that behavioural changes in plants and animals can occur as the environment changes. So how has the environment change? What else might be the cause for this?

4 hours later: I googled further into this and realised that speciation can occur in butterflies, and it has been simulated in laboratory before. Our senior lepidopterist also did confirm that this was possible previously through random pairings of  Heliconius butterflies, but limited to butterflies in the same genus.

Click here to read about the the speciation of a Heliconius hybrid. I can say that the butterflies in the genus of Heliconius are a truly advanced species. I might cover more about that at a later stage.
