  1. Korscheltellus lupulinus (L.) Moth Despite its noctuid-like appearance this species is distinguished by its very short antennae.
  2. Korscheltellus lupulinus (L.) Damage on lettuce The larva has severed the roots ; the plant wilts and dries.
  3. Korscheltellus lupulinus (L.) Larva By pulling up a wilting plant, the larva is revealed.
