quercus macrocarpa

branch from below
Quercus macrocarpa is cultivated by plant nurseries for use in gardens, in parks, and on urban sidewalks. Bur oak makes an outstanding ornamental tree. Among the white oaks, it is one of the most tolerant of urban conditions, and is one of the fastest-growing of the group. It has been planted in many climates, ranging northwards to Anchorage, Alaska, and as far south as Mission, Texas. It withstands chinook conditions in Calgary, Alberta.–wikipedia

Maladera castanea, Asiatic garden beetles

breakfast buffet for crows
The Asiatic Garden Beetles are back, feeding at night on tender oak leaves. The AGBs are attracted to electric light. Don’t swim well. So this tupperware pool, lit from below, attracts about twenty-five beetles per night. The beetles tread water until just after dawn when the crows come and enjoy crunchy breakfast buffet.

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
