Megachile texana
Texas Leafcutter Bee
Introduction:
The head and thorax are clad in short, dense whitish hair. The wings are semi-transparent with black veins. The abdomen is barred in black and yellowish-white. 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 25 cm (10 in) 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.
