Both EY aircraft appear to have been on the ground for less than an hour, which makes the fitting and removal of Pitot covers less practical, if Mud Daubner wasps are eager to make a " home".
I am no expert in their choices (someone may be). Whether they prefer or reject certain colours or smells could be factor in choosing to "paint" the front of a Pitot tube with that colour. Or a special shade, might be relevant.
( Birgenair had been without Pitot covers for some days in 1996. My Britannia had had both Pitots covered for our 24 hour stay in KIN in 1969.)_
( Swarming honey bees are somewhat choosy about where to settle. And when settled, can be gathered in a skep !)
