Synchlora faseolaria

Guenée, [1858]

emerald moth, wavy-lined emerald

Synchlora faseolaria is a of emerald moth in the Geometridae, commonly known as the wavy-lined emerald. The caterpillars are notable for their remarkable camouflage , adorning their bodies with bits of plant material from their plants to blend in with flowers and foliage. This species belongs to a of 12 North American species, with S. aerata being the most widespread in the eastern United States.

Identification

are small emerald green with wavy transverse lines on the wings. The caterpillars are distinctive for their camouflage , covering themselves with flower petals, leaves, or other plant debris that matches their current food source, making them extremely difficult to detect. When moving, they exhibit a characteristic herky-jerky swaying motion that mimics plant parts blowing in the wind.

Distribution

Middle America and North America (present in both regions according to GBIF records).

Seasonality

are active during spring and summer months. In eastern North America, activity occurs primarily in April through August, with peak varying by latitude.

Diet

Caterpillars feed on a variety of herbaceous plants and flowers including chrysanthemums, daisies, asters, black-eyed Susans, coreopsis, goldenrods, Joe Pye weed, ragweed, raspberries, roses, sage, St. John's wort, yarrow, and many other composite flowers.

Life Cycle

Complete with , larva, pupa, and stages. Caterpillars are the feeding and growing stage, during which they employ their distinctive camouflage . occurs in a cocoon, and adults emerge as small emerald green .

Behavior

Caterpillars actively collect and attach pieces of plant material to their bodies using silk, creating a dynamic camouflage that changes as they move to new plants. They sway back and forth when stationary to enhance the illusion of being plant debris. This is one of the most sophisticated examples of active camouflage in insects.

Ecological Role

As herbivores, caterpillars contribute to flower and foliage consumption in diverse plant . Their specialized camouflage makes them important subjects for studying -prey dynamics and evolutionary adaptations for .

Human Relevance

Occasionally found in gardens and ornamental plantings where their feeding may cause minor damage to flowers. Their remarkable camouflage makes them a subject of interest for naturalists and photographers, though they are challenging to detect.
