The behaviour of P. triangulum was observed in a laboratory observation cage containing dry sandy soil. The female made a burrow at an angle of 25 deg to the horizontal. She then emerged from the burrow, usually closing the entrance with a sand plug, and hunted for honeybees. Upon returning with a paralysed prey she removed the plug whilst still holding the honeybee. The bee was dragged inside by the wasp's hindlegs and deposited halfway along the burrow.
