Osmia leaiana

Tough little Osmia leaiana sits it out till Late Oct 2016 In 2012 I had my last Osmia leaiana nesting at my new address although I made the film the year after. Her offspring never made it and I opened the cocoons to see why, late July 2013. Most of them were dead but a few […]

There were 1000’s on the red mason bee cocoons, with their pinkish plates and colourings (Chaetodactylus osmiae ?) which were mobile and crawling […]
