Six-spotted Leaf Beetle

The Six-spotted Leaf Beetle (Neolema sexpunctata) is a member of the subfamily Criocerinae (Shining Leaf Beetles),  family Chrysomelidae (Leaf Beetles). According to BugGuide, "Chrysomelids are phytophagous and are among the most diverse and conspicuous insect families on plants. The adults feed on living plant material, usually consuming leaves or sometimes various flower parts including pollen. Many chrysomelid larvae feed on leaves, but a great number are subterranean, attacking roots and underground stems."

Specifically, N. sexpunctata is a shiny red beetle, with a distinctive pattern of 6 black spots on the striated elytra. It can be confused with N. quadriguttata, the Four-spotted Leaf Beetle, but N. sexpunctata has of course the additional humeral spots (5 and 6), is larger, and the elytral punctures of the striae are smaller and more dense than in N. quadriguttata. In the latter, the elytral punctation is fewer, deeper and often seems to be missing a few in the striae.

N. sexpunctata is associated with Commelinaceae, a family of flowering plants known informally as the dayflower or spiderwort family. Dayflowers belong to the genus Commelina, while spiderwort belongs to the genus Tradescantia.

I found this specimen on Camellia (family Theaceae).
