I've read of aircraft being grounded because pitot probes (the little tubes that collect air to measure airspeed) were blocked by insects - solitary bees, most probably - nesting inside.
Carpenter bees (Xylocopa violacea - big rumbly black things with iridescent purple wings that Mike probably gets in his French garden) evolved to nest in natural tunnels in rotting wood, but I've seen them nesting in the steel tubes of garden furniture, so it's not that big a stretch to imagine bees finding their way into a little-used engine.
P.S. Is an 'environmental technician' a dustman?
