You can stop worrying about the bees .... they're all at my house!!
Then a couple of days ago I went into the spare bedroom and heard a strange chewing sound coming from the loft. Through the window I spotted a couple of small bees going under the house guttering: further inspection revealed a hole between two bricks. No idea what kind they are. Dread to think how many there are up there living rent free ... and what ARE they chewing?!
Today I spotted holes in the leaves of one of my new shrubs. Leaf-cutter bees! These are solitary bees. They carry the bits of leaf away to line cells in which they lay eggs. This one is my own fault as I placed one of those insect boxes near the pond and sure enough someone has moved in! The books tell me not to panic as they don't do any harm ... the shrub wouldn't agree! "Just look at my leaves!!"
Anyway, on the whole I am rather chuffed at all these pollinators. I'm obviously doing something right!
