Where have all the bees gone?

Back in the UK we had a huge bee population on a flowering shrub in our front garden.

I would park the car , get out, and about fifty bees would nod "Morning"( this is obviously were the idea for the fish tank in Monty Pythons "Meaning of life" came from).

Since arriving in Canada I do not recall seeing any, until this one yesterday, it didnt say any thing, it was probably shy/French/busy, but it was good to see one around.

Apparently they are under a general threat from changes in land use , gardening practices, an increase in natural predators. The Scientists are encouraging us to grow more trumpet shaped flowers , bees can see UV markers on flowers but not the colour red.

There are thousands of bee species but only a very few used by man to produce honey and pollinate some commercial crops.This bee may be the common honey bee (Apis Mellifera) or its closely related cousin the bumble bee which tends to be larger and furrier than other types, it didnt say..
