Bees and Butterflies from Tanzania

Hello! Many greetings. I’ve been exploring different parts of East Africa and would like to share some of the wonderful insects that I encountered here.

I recently went hiking in the Pugu Hills which are near the port city of Dar es Salaam in Tanzania. These hills contain some precious fragments of forests that once covered most of the East African coastal areas. However, today only tiny patches of forest remain. These forests are home to a lot of different species that aren’t found anywhere else in the world including trees, butterflies and other insects.

Here are a few of the remarkable insects that I came across during the walk in the Pugu Hills.

One of the first creatures that we spotted was this remarkable Hairstreak butterfly (Hemiolaus sp.). It flies fast and furiously along the forest trails – but only when it alights can you appreciate its delicate beauty. The elaborate tails on the right are actually a false head that serve to lure would-be predators away from the butterfly’s real head, thereby allowing it to escape. This is a common strategy in this family of butterflies that are known as the ‘blues and coppers’ or lycaenids (Lycaenidae).

A few minutes later a flash of copper whirled by and stopped to rest in a patch of flowers. This is one of the Scarlets (Axiocerses sp.) another of the interesting members of the lycaenid butterfly family. Here you can see it’s false head in place:

And here is one that escaped a predator with the false head missing:

Even though the butterfly is now damaged, it survived the attack and can go on to mate and lay eggs and therefore contribute its genes to the next generation: this is what these amazing adaptations are all about – increasing the chances of survival and reproduction.

At the edges of the forest in the tall grass there were numerous Acraea butterflies basking in the sunshine:

A few minutes later I came across yet another lycaenid butterfly species, this one is known as ‘The Playboy’ (Deudorix sp.):

Flying elegantly through the forest were numerous swallowtails, which are large and showy butterflies, including this beautiful Eastern White Lady (Graphium sp.):



Of course the bees were not to be outdone, and as the day grew hotter, they came out in large numbers to visit the different flowers in search of nectar and pollen. Most of the bees were visiting wildflowers at the edge of the forest and along the trails.

There were a lot of bees about, and sometimes it seemed like they needed some air-traffic control as they approached the flowers in droves!

At the forest edge there were lots of Macrogalea bees visiting various wildflowers. Macrogalae means ‘long tongue’, and the bee uses its long tongue to sip nectar from the flower:

The carpenter bees were hard at work too, especially on the flowering trees and shrubs in the forest:

After a wonderful day walking through the forest, there was yet one more special beauty waiting in the shadows. While this is not the most brightly coloured of butterflies, it is a coastal endemic and flies softly in the shaded groves of the forest: the enigmatic and delightful Spotted Sylph:
