I went flying in the Chippy last week, and during my pre-flight I'd left the cowlings and canopy open while I went back to the hangar for some oil. On returning I was just in time to see an enormous wasp hover into the cockpit and disapear under the panel.
I wafted my map under there vigorously, and it re-appeared and flew off.
Would have been most unpleasant to be sharing the cosy confines of the DHC1 cockpit with that beast while in the air!
