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.

Rare
Under 5% of wildlife watchers report a Wavy-Lined Emerald sighting in Edmonton on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 194th most-seen of the 390 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Wavy-Lined Emerald is recorded against all the insects logged in Edmonton (12 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
