Miner Bees

The miner bees have hatched today and are quietly flying about the garden.  We are always happy to see them and feel pleased to have them living in our garden.  The extra shows the little pile of the earth that they make as they appear from their underground passages.  I have added some extra info about them-
'Evidence of them may be seen if you come across little mounds of earth in lawns, borders, or even in pots, resembling worm casts. Nests will often consist of one small, main tunnel, with perhaps 5 or so branches, each containing an egg cell. The tunnel will usually be about 20cms – 40cms deep, and the entrance is about the size of a 10p coin. The nests will not cause any damage in soil or in gardens, and indeed, they should be welcomed. They rarely, if ever sting, and provide an excellent pollination service. The use of pesticides in lawns to deal with them is not recommended. Nests are very short lived, do not damage plants, and many lawn pesticides are actually harmful to earthworms'
