Hi,
I havent written anything to this list before, but i found myself wondering about this now almost legendary Painted Lady migration.
Maybe someone can help,
First is there a recommended text written about the butterfly migration phenomena ?.
Migration in general is kind of hard to get the mind around, how is it that thousands or millions of individuals all have the same 'idea' at the same time.
Where does the impulse come from?
Is there an external trigger, or is it built into evolution?
Is it a learned inheritance maybe, did a lot of species members perish until it was found that travelling vast distances was beneficial to the species.
Are the distances constant or getting greater or smaller.
What will the butterflies do when they get to sea again after crossing the british mainland, do they ever reach the outer islands, if so why.
Just rambling thoughts
Ray
have a good weekend all
:)
