In its native range it is known to use man-made cavities to 21 construct nests. A series of serious safety incidents Brisbane Airport related to the 22 obstruction of vital airspeed measuring pitot probes on aircraft possibly caused by 23 mud-nesting wasps at prompted an assessment of risk. An experiment was designed 24 to determine the species responsible, the types of aircraft most affected, the 25 seasonal pattern of potential risk and the spatial distribution of risk on the airport.
