Narrative:
I was the pilot flying performing the takeoff. During the takeoff roll the captain called '80 KTS' and then leaned forward and deactivated the autobrakes from 'rejected takeoff' to 'off' and stated 'my aircraft' 'aborting takeoff'. The captain then closed the throttles; moved them into 'rev' and spoilers deployed. I noted 110 KTS on the airspeed ribbon and held the yoke forward; called deployed and no autobrakes. I inform the tower that we were aborting the takeoff. The captain stated that during airspeed crosscheck he noted that the standby airspeed indicated had not moved off its parked position of 30 KTS. The deceleration was very gentle and there appeared to be; and felt as if no heavy braking if any braking was taking place. The captain said that he was not using brakes or very little braking. We rolled to end of the runway and exited.the tower asked if we needed assistance and the captain said no. On exiting the runway; I informed ground that we will be returning to the gate and they too asked if we needed assistance. Again the captain said no. During this time the captain had instructed the relief pilot to contact the cabin and inform them of the situation and then the relief pilot called the company. We taxied in to our gate; and maintenance came out to inspect the aircraft. A mud wasp was found to have made a nest in the standby pitot tube which result in no airspeed indication from the standby instruments. All of the us: captain; first officer and relief pilot were into the brake cooling charts I found that each of us had a different opinion as to what our cooling should be. I believed we should enter the chart at 110 KTS but the captain said it should be at 85-80 KTS; as this was where he believed he began to apply brakes. The aircraft was taken out of service. Maintenance has a procedure for covering the pitot tubes if an aircraft sits for 24 hours or more. This aircraft sat for 8 hours. I believe that practice should be revised to a time less then 24 hours. Also high speed; low speed aborts should be discussed more because we; the cockpit crew; had a disagreement as to whether this was a high speed or low speed abort.

Title: A B767 Captain; the pilot not flying; rejected a takeoff at about 100 KTS when he noted the Standby Airspeed Indicator at zero. Upon returning to the gate Maintenance discovered a wasp's nest in the standby pitot tube.
Narrative: I was the pilot flying performing the takeoff. During the takeoff roll the Captain called '80 KTS' and then leaned forward and deactivated the autobrakes from 'RTO' to 'OFF' and stated 'My Aircraft' 'Aborting Takeoff'.
