Let's describe the external structure of an adult housefly. The external structure of an adult housefly (Musca domestica) is divided into three main body parts: the head, thorax, and abdomen. 1. Head: Features a pair of large, compound eyes that provide a wide field of vision. Has a pair of short antennae used for sensing smell and touch. Possesses a proboscis*, which is a specialized mouthpart adapted for sponging up liquids like nectar, sugary solutions, and decaying organic matter. 2. Thorax: This is the middle section and the center of locomotion. It bears one pair of wings, which are membranous and used for flight. Houseflies have reduced hindwings called halteres*, which are small, knob-like structures that help with balance during flight. It also has three pairs of legs*, each adapted for walking and sensing. The legs have sticky pads (pulvilli) that allow the fly to walk on smooth surfaces. 3. Abdomen: This is the posterior part of the body. It contains the digestive organs, reproductive organs, and respiratory openings (spiracles*). The abdomen is typically segmented and can vary in shape and size depending on the sex and physiological state of the fly. Send me the next one 📸
