  Quotations
  Réaumur, in his account of the insects which attack the aphides, has described the larva of a Coleopterous insect, which he names "l'hérisson blanc", or "le barbet blanc", of small size, and remarkable for having the body clothed with small bundles of oblong, white, cotton-like "touffes" ... I have met with this larva ... it evidently ... belongs to some species of the genus Scymnus.
