anisopteryx vernata - Collaborative International Dictionary of English v.0.48 :

  Cankerworm \Can"ker*worm`\, n. (Zool.)
     The larva of two species of geometrid moths which are very
     injurious to fruit and shade trees by eating, and often
     entirely destroying, the foliage. Other similar larv[ae] are
     also called cankerworms.
     [1913 Webster]
  
     Note: The autumnal species (Anisopteryx pometaria) becomes
           adult late in autumn (after frosts) and in winter. The
           spring species (Anisopteryx vernata) remains in the
           ground through the winter, and matures in early spring.
           Both have winged males and wingless females. The
           larv[ae] are similar in appearance and habits, and
           belong to the family of measuring worms or spanworms.
           These larv[ae] hatch from the eggs when the leaves
           begin to expand in spring.
           [1913 Webster]
