Synchlora aerata, the wavy-lined emerald moth or camouflaged looper, is a species of moth of the family Geometridae. The species was described by Johan Christian Fabricius in 1798. It is found in the United States and Canada.

The wingspan is about 17 mm.

The larvae are loopers (inchworms) like the rest in the family. They feed on composite flowers, shrubs, and trees. Recorded food plants include Aster, Rudbeckia, Liatris, Solidago, Artemisia, Achillea and Rubus species. The species overwinters as a partially grown larva.

The caterpillars employ the unusual behavior of affixing bits of the plant tissue on which they are feeding to the several large spines on their back. This provides cover from gleaning birds that rely on keen eyesight. The camouflage can also block smaller animals from sensing them.
