A native of Japan and China, where it is not an important pest, the
Asiatic garden beetle (Maladera castanea) was first discovered in
the United States in New Jersey in 1922. Asiatic garden beetle grubs
feed off the roots of grasses and weeds in early spring. Adult beetles
attack many different vegetable, herb, fruit, and ornamental plants,
feeding mostly at night where they strip, shred, and notch the foliage
of their hosts. Asiatic garden beetle damage is especially prevalent
around the leaf margins.–University of New Hampshire
