During takeoff at the 80 KT airspeed indicator check; my (first officer) airspeed indicator was not indicating any airspeed. The captain rejected the takeoff at approximately 90 KTS. We let maintenance troubleshoot the problem. They found a relatively large bug in the first officer pitot tube. Once they cleared the pitot tube; we were able to takeoff on the next flight without incident.
