Pachodynerus nasidens
Keyhole Wasp
Pachodynerus nasidens, commonly known as the keyhole wasp, is a solitary mason wasp in the family Vespidae, subfamily Eumeninae. Native to the Neotropics, it has been introduced to Hawaii, Micronesia, Australia, and the northern United States. The species exhibits remarkable nesting plasticity, utilizing abandoned insect galleries, human-made cavities, and even aircraft pitot tubes. Females provision nests with paralyzed caterpillars as food for their larvae. The species has gained notoriety for causing aviation safety incidents by blocking pitot probes with mud nests, leading to unreliable airspeed readings.
