Draw a large labelled diagram of a an external structure of an adult house fly

Here is a labelled diagram of the external structure of an adult house fly:

• Head:

  • Eyes: Large, compound eyes, often reddish, occupying a significant portion of the head.
  • Ocelli: Three small simple eyes arranged in a triangle on the top of the head.
  • Antennae: Short, with a feathery arista (bristle).
  • Mouthparts: Sponging type, adapted for lapping up liquids.

• Thorax:

  • Prothorax: Small, bears the first pair of legs.
  • Mesothorax: Largest part, bears the wings and the second pair of legs.
  • Metathorax: Small, bears the halteres and the third pair of legs.
  • Wings: One pair of membranous wings, used for flight.
  • Halteres: Small, club-shaped structures located behind the wings, used for balance during flight.
  • Legs: Three pairs of legs, each with a coxa, trochanter, femur, tibia, and tarsus (ending in claws and pulvilli).

• Abdomen:

  • Segmented, typically oval or elongated.
  • Contains spiracles for respiration along the sides.
  • Terminal segments modified for reproduction (genitalia).

[Imagine a simple line drawing here showing these parts clearly labelled. The head would be at the front, followed by the thorax, and then the abdomen. The large compound eyes would be prominent on the head. The single pair of wings and the small halteres would be on the thorax, along with the three pairs of legs. The segmented abdomen would extend from the thorax.]
