Do you start looking for wild Blackberries (Rubus spp.) this time of year? If so, keep an eye out for this unique caterpillar that feeds on native Blackberry leaves.
It’s called the Camouflaged Looper (Synchlora aerata), and for a good reason. To avoid predators, Camouflaged Loopers adorn themselves with fragments of the plant they’re feeding on! They clip off bits of flowers and leaves and then attach them to their back with silk. For instance, this caterpillar’s back is adorned with the pollen-bearing anthers of blackberry flowers! When the caterpillars moult or switch host plants, they even do a costume change to match their new host plant!
Camouflaged Loopers feed on a wide variety of native plants, including fleabanes (Erigeron spp.), goldenrods (Solidago spp.), coneflowers (Rudbeckia spp.), bonesets (Eupatorium spp.), and blackberries (Rubus spp.).
