Large Maple Spanworm Moth

Prochoerodes lineola

The Large Maple Spanworm Moth, or Prochoerodes lineola, is a small but distinctive species of moth found throughout North America. The wings of the Large Maple Spanworm Moth are predominantly brownish-gray with dark brown markings, and the wingspan of this moth ranges from 3.5 to 5 cm.

One interesting characteristic of the Large Maple Spanworm Moth is its ability to disguise itself in both its caterpillar and adult form. The caterpillar is known to disguise itself as a twig by straightening out its body and becoming stiff, resembling a small twig. This helps to deter predators that may mistake the caterpillar for a potential food source.

The adult moth, on the other hand, can disguise itself as a leaf. When at rest, the moth holds its wings in a unique position that resembles a leaf on a branch. This adaptation helps the moth blend in with its surroundings and avoid predation.

The Large Maple Spanworm Moth is also nocturnal and is attracted to light sources, making it easy to observe at night. The adult moth is distinctive, with a unique pattern on its wings that ranges from light to dark brown with dark markings.

The caterpillar of the Large Maple Spanworm Moth is known to feed on various plant species, including the leaves of maple trees. Despite its small size, the Large Maple Spanworm Moth is a valuable species to observe in the field due to its unique appearance and interesting behaviors.

The ability of both the caterpillar and adult moth to disguise themselves in different ways makes the Large Maple Spanworm Moth a fascinating addition to any field guide for North American moths.
