I posted some pictures on a Megachile thread earlier...
Megachile sp.
but now have a distinct question that needs space of its own.
This picture clearly shows a nest-hole sealed with a petal. Is this a Megachile sp. behaviour or are we looking at another genus here?
It looks remarkable in real life. All the cells in the block up to this point were cut out of leaves.
Anyone out there to enlighten me, please?
