Here’s a picture of a bee seen in early September at the Urb Farm in Wolverton, which we have identified as a non-British species, the Alfalfa Leafcutter Bee (Megachile rotundata)
While honeybees get much of the fame, Alfalfa Leafcutter Bees are actually 15-20 times better at pollinating than honeybees. The female leafcutter bee carries pollen on the underside of her hairy abdomen, scraping it off upon returning to her nesting hole to create a pollen loaf (food) for her egg. Using her large jaws she will cut a perfectly circular hole from nearby leaves (generally only up to 300 feet from her nesting hole) to create a cocoon of leaves for her egg to develop. A solitary bee, the Alfalfa Leafcutter Bee is often found nesting alongside its neighbours in bee hotels and these fascinating creatures are well worth having in your garden!
We have plenty of habitat just perfect for leafcutter bees, so we have been pleased to welcome them. We have seen a fair few different types of leafcutter/solitary/bumble bee at the farm over the years, and particularly this year.
