Dear All, Hello – sorry for not posting more often. Have been sorting out getting online stuff. Hopefully this now works… Here are some photos of ants on flowers that I recently took. Many ants visit flowers, but they rarely serve as pollinators. Mostly they just steal small amounts of nectar, so they are effectively robbers. However, one group of plants, such as the succulent Euphorbias in Kenya, do include ant-pollinated flowers…More soon – I promise, and many, many thanks to everyone for the kind comments! 
Welcome back! Looking forward to more of your fascinating and informative posts.
Hey Dino,
Just checking in. Do post when/if you get more time!
Just Awesome! Here in Brazil some succulents are polized by ants, but some times they live inside the fuits of the cactus and the others animals cannot eat it.
