A butterfly is an insect with two pairs of colorful wings that are covered with scales. Here is a brief description of the labeled parts of a butterfly:

• Antenna: The sensory appendage on the head that is used for smelling and feeling.
• Head: The front part of the body that contains the brain, eyes, and mouthparts.
• Eye: The large, compound eye that is made up of many small lenses.
• Thorax: The middle part of the body that contains the wings and legs.
• Forewing: The upper wing that is attached to the thorax and is used for flight.
• Hindwing: The lower wing that is attached to the thorax and is used for flight.
• Abdomen: The rear part of the body that contains the digestive and reproductive organs.
• Wing vein: The network of narrow, transparent tubes that support the wings and help to channel fluids through the wings.
• Scales: The tiny, overlapping structures that cover the wings and give them their color.
• Proboscis: The long, tube-like mouthpart that is used for feeding on nectar from flowers.
• Legs: The six jointed appendages that are used for walking and clinging to surfaces.

These are the main labeled parts of a butterfly. Different species of butterflies may have variations in the shape, size, and coloration of these body parts.
