We have some exciting news to share! Mason bees (Osmia rufa) are making nests inside the bamboo cane bug box, sited on the allotment shed. Mason bees are solitary and do not form colonies or produce honey. The Mason bee gets it name due to using mud in building nest compartments, rather like a stone mason constructing a house. After mating, males die and females begin collecting pollen and nectar to build nests. After laying her eggs (males at the front and females at the back), the female seals the entrance to the tubular nest using mud. Mason bees may nest inside reeds or holes in wood made by wood-boring insects, some British species make their nests in empty snail shells. Luckily for us, 3-4 females have chosen to use our bug box.
The bug box is in full sun, sited approximately 5′ 8″ high, this is the first time the box has been used by bees. The bees were very calm considering we were about, using the shed and nearby area as we usually would. Mason bees are usually non-aggressive and will only sting if they are really threatened, ie being held between fingers. They would much rather get on with the job of building a nest rather than defending it.
We’re thrilled to be able to watch the bees, they’re brilliant little pollinators and very welcome on our plot. Plot 4 is certainly living up to its name – The Little Haven.
