Pollinators hard at work!
“One in three bites of food can be attributed to a pollinator”. This statement is often quoted by biologists around the world when talking about pollinators and their importance to our lives.
In Africa pollinators are primarily wild insects that travel between farms and natural habitat, and are extremely vulnerable to habitat loss and destruction.
Pollinators intimately link wild species with basic human livelihoods. The relationships between insects and flowers are at once ancient, beautifully intricate and correspondingly fragile.
These intricate and essential links between wild species, natural areas and food production were beautifully evident on a recent visit I paid to a farmer in Western Kenya. Lucy Murira grows a wide range of vegetables and fruits for her family. Her farm is located in the Nandi Hills nestled between tea plantations and forest patches. It is these forest patches that provide the pollinators for Lucy’s crops. Below is a short video showing some of the crops and pollinators on Lucy’s farm. (Please forgive the sloppiness of this video - it is my first attempt at doing this!)
As mentioned in the video, one of the important and nutritious crops growing on this farm is ‘Njahe’ a local variety of blackbean. It is a verdant climber with lovely pinky-lilac flowers.
The main pollinators of the blackbean here appear to be wild bees, including these lovely, robust and fast-flying carpenter bees.
Without the pollinating visits of these hardworking bees, there would be no pods to harvest.
One of the other crops growing here that benefits from pollination is the butterbean. As Lucy says, these are really yummy (in fact one of my favourites!). Skipper butterflies and bees were pollinating the butterbeans on this farm. All of them need the patches of forest to survive.
Pollinators need a clean, safe and pesticide-free environment to survive. Lucy’s farm is filled with a huge number of different pollinating insects. Not only were pollinating insects thriving on the farm, we even found this little reed frog dozing among the tendrils of the butterbeans!
More from the wonderful world of bugs soon!

Happy little Buffs…

Hello!
Sorry for not posting more often – have been really busy chasing after bugs now that the rains have started and they are popping out all over the place!
Many, many thanks to everyone for their kind comments on the blog post ‘Ants in the dust’. I will try and post a link to the BBC piece on it when I can figure out the technical side of it today or tomorrow.
A couple of days ago in a tiny forest fragment near Nairobi I spotted these little beauties whirling about some buds. From a distance they looked like tiny little orange flames dancing in the dappled light. On taking a closer look I saw that they were tiny orange and brown lycaenid butterflies.
Known as ‘Buffs’, these tiny jewels are part of a large and diverse group of butterflies in the family Lycaenidae. This species is Baliochila fragilis – an apt name for their delicate build. The caterpillars of these butterflies feed on lichens, often high up in the forest trees, so it was interesting to find them hovering about near the ground.
Looking closely at the butterflies perching on the buds of the Chlorophytum, I noticed that there were a lot of ants running up and down the buds too. And then I noticed that the butterflies had their tiny proboscis unfurled and were feeding from in between the young buds. These buds secrete extra-floral nectar which is intended to attract ants that then patrol the buds and protect them from would-be nibblers of the insect-kind. However, as the butterflies posed no threat the flowers, the ants seemed to tolerate them.
In fact, the butterflies were so relaxed that quite a few of the males were courting the females. The pair in the video clip below show the typical interaction. The male sidles up to the female. She rejects him with a flick of her wings and moves on trying to keep feeding. He follows her and flicks his own wings at her trying to win her over… She rejects him and keeps on moving… the cycle is repeated over and over again. I guess eventually some of the most perseverant males win one of the females over!

More butterfly eyes!

Dear AllSorry for not posting more - have been travelling - lots to share, just working on getting it all sorted. In the mean time here are some more close-ups of butterfly eyes - enjoy - the Emperor Butterflies below are particularly striking! The first one is a close-up of the Green-Veined Emperor, and the second is of a Black-and-White Charaxes. These are both fast-flying denizens that sweep through the forest canopy at high speeds and rarely venture down close to us mere mortals unless drawn by the scent of some rotting fruit or something even more appetizing like carrion!

Butterfly eyes…

Dear All, thanks for your kind comments about the Butterflion. If you are in Nairobi please go and visit him at the Sarit Centre outside the Text Book Centre. Here are some close-up pictures of butterflies that I took over the last couple of days. The pictures show their amazing compound eyes and mouthparts - which consist of a long tubular proboscis. More soon - enjoy the weekend!
