Underneath the pavement

So often I seem to be dashing out of the house and hurrying off to do something. Head down and scurrying along pavements you often don't spot the changes, a different type of city regeneration. There is lots going on unplanned within the built environment. Like the blogger of Organic Allotment I too have spotted a self sown tomato plant growing out from a crack between the pavement and the wall of a city college. Seeded no doubt from a discarded sandwich filling of a passing student.

This might go unobserved by most of us but nature is always on the look out for opportunities. In the neglected front yard of a terrace house a colony of cinnabar moth lavae are munching their way through a ragworth plant. These beautiful black and vermillion moths only lay their eggs on this plant. The warning stripes of orange and black a message to birds that they have ingested the toxins from this weed and won't be good to eat.
A buddleia bush growing down a crack in a nearby wall offers nectar for bumble and honeybees. They are so attracted to the flowers that there is a bit of jostling going on. It's crowded at this new nectar bar in town.

The flowering herbs in the back yard have created quite a buzz. It still amazes me how you can so easily attract beneficial insects with just a few plants and flowers in a city yard. There seems to be around eight or so bumble bees on the herbs at any one time, collecting nectar. I'm reading 'A World Without Bees' at the moment which helps to explain some of the behaviour. Here's what I have learnt:
1. Bumble bees prefer purple flowers while honeybees have a preference for white blooms
2. Honeybees are great pollenators because they will keep making thousands of visits to one flower species at a time until they have used up all it's nectar.
3. The antennae on a bee's head allow it to smell in stereo.
