      w118 mutant larvae are less responsive to gentle touch.

      (Titlow et al., 2014)

      w118 flies exhibit increased survival time compared to wild-type.

      Statement
      Reference

      The mechanosensory phenotype seen in SmnE33 larvae is rescued by crossing with w118, but crawling speed is not restored to wild-type or SmnE33/+ levels.
