The hornet's lunchtime

The hornets continue to fascinate me.  Much of the time they are chewing bananas in a dish but the workers are still hunting in the flowers.  When a hornet catches a fly the procedure is always the same.  It flies to a nearby leaf and hangs from its back legs.  Then it bites off the head, wings, legs and abdomen and flies back to the nest with the thorax.  The flight line into the woods is always the same but we haven't yet found the nest.
