Hi James,
I live at Shimoni, 80 kms south of Likoni, Mombasa. I was returning from Mombasa on
Wednesday 21st February in the afternoon - 3.30 - 4 p.m. and noticed a lot of these
butterflies all along the road towards the turn off to Kwale.
Yesterday Friday 23rd February I was driving from Diani to Tiwi at about midday and
again there were a good number of these butterflies along the road and again in the
afternoon returning to Shimoni. Once I had passed Diani, the butterflies stopped,
obviously they had not yet reached there yet. The butterflies were spread out, rather than
in close bunches, but plenty of them.
I have not seen this congregation of butterflies down here for some years. We have had
them in the past, I remember out at sea in 1969 when the weather was very odd, the
Kaskasi virtually failed and we only blew for two weeks in the last two weeks of January,
and therefore the fishing was very poor, and we amused ourselves butterfly watching,
there were millions of them out in the Pemba Channel. We have had other years when
there have been similar concentrations in Tsavo National Park when we have been
driving to Nairobi and you drove through non stop butterflies!! This was usually April.
Regards,
Maia Hemphill
