The banded longhorn beetle is a North American flower longhorn beetle.
The adult banded longhorn beetles eat nectar from flowers while the larvae live on decaying wood.
The color pattern of the adult banded longhorn beetle is likely a case of mimicry — the beetle pretends to be a wasp so that predators leave it alone.
