Head
Honeybees and bumblebees have black heads, eyes and antenna. Their heads are often also speckled with yellow.
Body
Most species possess the characteristic black and yellow stripes on their body. These colors signify a warning to predators, suggesting that preying on the bee could be hazardous.
Legs
Bees' legs are black, often with a hint of any other coloration that appears on the body -- yellow or amber, for example.
Wings
Bees' wings are clear with dark membranes, perhaps black or dark brown.
