N2458G

The pilot reported that during the late stage in his approach to land, he was distracted by a large insect that hit the windscreen. Simultaneously, a gust of wind disturbed the aircraft attitude which resulted in an overcompensation of the flight controls and subsequent airplane porpoising. This lead to a premature touchdown and caused the airplane to bounce. As the airplane bounced, the propeller struck the runway and the nose tire deflated, substantially damaging the firewall and lower fuselage. The pilot stated he did not experience any mechanical problems with the airplane prior to the accident.
