The nests of
Megachile texana often occur in pasture, with the entrance being under a rock, under a clod of earth or in one case, on a small hillock. The burrows may be up to long and the upper side is often the underside of a flat stone. Sometimes a pre-existing cavity is used, but females have been observed excavating their own nests. A single cell or several cells may be constructed, each lined with cut portions of leaf in a similar way to the nests of
Megachile rubi. Each cell is half-filled with a mixture of
pollen and
nectar and an
egg laid on the food mass. The
larva consumes its food supply and when sufficiently developed becomes an inactive prepupa enclosed in a
cocoon which fills the cell. The outer surface of the cocoon is wound round with brownish threads. ==References==
