Sphinx Moth (hawk or hummingbird moth)

Characteristics:

  • Eggs: Females lay eggs on the underside of leaves.
  • Larvae: Larvae feed on the leaves of ash trees and other trees, but do not cause severe defoliation. The green larvae can grow up to 6 cm long and have a horn or spine-like projection at one end. It’s not a stinger, nor is it poisonous!
  • Adults: Full grown, adults have brown wings with white stripes and medium to large spindle-shaped bodies. Their front wings are long and narrow and may span 2 cm or more. Adults are strong fliers and move just like hummingbirds, hovering over flowers to sip nectar for food.

Identifying infestations: Larvae or moths rarely infest any area; they cause little damage or no damage to plants in your yard.
