In two subfamilies of this order, Panurginae and Anthophorinae, the scopa is enlarged on the fourth tibiae.  
In two subfamilies of this order, Panurginae and Anthophorinae, the scopa is enlarged on the fourth tibiae.  In halictines, the scopa is part of a larger structure called the corbicula, while in Hyaleinae microgametophytes from flowers are carried directly in the digestive track. The two suborders, symphta and apocrita, are distinguished on whether ther junction between the thorax and abdomen is constricted, giving wasps their distinctive appearance. For ten points, give the name for this "membranous-winged"  order of insects that includes bees, wasps, and ants.
