White flowers of summer
A bunch of white flowers of summer, with a few associates:
The caterpillar is the moth Camouflaged Looper (Synchlora aerata), one of the few caterpillars that attaches plant fragments to itself. The fragments aren’t from boneset, the hairlike filaments are from an aster. The hydrangea and the last flower (an annual Euphorbia species) are garden ornamentals.
