Leaf-cutter bees clear out the nesting tubes
An update on what the leaf-cutter bees are doing at the moment. Some bees are still hatching. The clicking sound of the bees nibbling away at the dried leaf cells is very audible if you’re sitting anywhere near the tubes, so it’s easy to know when they are working their way out! Here is a previous post showing leaf-cutter bees hatching, and here you can see that they are now hatching from the wooden bee house:
I feel I must say that although this bee house above looks beautiful, as you can see the bees have not favoured it, and prefer the cylinder-type houses. The reason for this seems to be that many of the holes are simply the wrong size or shape. One bee last year attempted to nest in one of the lower holes, and gave up the attempt (see above, right). The two circular holes either side of the ones which have been nested in cannot be used at all, because there are small nails blocking the tubes. So if you are purchasing bee homes, please look out for all these things before making a selection.
Meanwhile, bees that have been about for a week or so are looking for suitable nest sites. So if you have put up some bee houses (which you can order from e.g. here or here) recently, or have nests from last year, this is the kind of thing to look out for. On the left, the bee is exploring the new tubes, centre picture she seems to have chosen to re-use one of the old tubes, and emerges with white paper, which is thrown below as debris (far right):
Finally for now, one of the bees resting after emerging, and enjoying some of the garden flowers (see more plants to attract bees here):
