Insects on the windshield can be dealt with, but in the pitot static system they can be truly maddening. Bugs, like birds, can build a nest overnight. Unlike birds, they can get into the smallest of orifices.
Recently, after many hours of troubleshooting and equipment changes, a recurring F900 aileron feel light was diagnosed as having bug larvae partially blocking the standby pitot tube. The bugs were lodged in the aft corner at the 90° bend. Applying pitot bench pressure in the hangar did not show the anomaly.
This is a reminder to cover and protect!
