What’s in an image? Sometimes quite a lot, more than meets the eye. I’m posting an image every two days or so.

Like all plants and animals, bees are pretty well suited to the actions they need to perform to live and reproduce. That’s what evolution does, it homes in on the best shape and size of wings, the optimum size for flight muscles, best arrangement of hairs on the legs to brush loose pollen towards the pollen sac for collection and transport, the best mouthparts for collecting nectar and so forth.

Quite a challenge, and an astounding achievement, but entirely doable by making small, random changes and selecting the best.

Here’s an example to make that bold claim clearer. If a random change enables the worker bees to carry on just a few days longer in the autumn, the hive will have slightly larger stores of honey for the coming winter. That hive will survive when a hive with less capable workers might not. And that’s enough. The new queens from the surviving hive will carry the altered gene and it’ll be present in the workers of the new colonies those queens create. The altered colonies will also survive in slightly colder places than before so will succeed at slightly higher altitudes and in slightly cooler climates.

The worker honeybee in the photo is collecting pollen. Insect-pollinated plants have slightly sticky pollen that lodges on the bee’s hairy body. Bees visit flowers to collect nectar from the base of the petals, but get dusted with sticky pollen in the process. Bees clean themselves like most insects (you’ve probably seen houseflies doing it, sweeping off particles of dust with one leg while standing on the others). When bees clean themselves, most of the pollen end up stuck together as a lump and lodges on a series of special hairs on the hind legs. Look closely and you can see this bee’s pollen load on its rear leg; an orange/yellow colour. Pollen is protein rich and the bees feed it to the bee pupae in the hive.

The plant feeds the bees nectar for energy and pollen for growing young bees; while the bees move pollen from flower to flower, and often from plant to plant over quite long distances, sometimes a mile or more. So the bees and the plants both benefit, it’s a useful co-operative effort.
