Mosquito Anatomy

1: Proboscis

The elongated mouthpart, or proboscis, is a specialized structure in female mosquitoes for piercing the skin and extracting blood. Male mosquitoes have shorter mouthparts adapted for feeding on nectar.

2: Antenna

Mosquitoes have two long, segmented antennae, which are sensitive to odors and help them locate hosts.

3: Wing

Mosquitoes, like many other insects, have two pairs of wings, making a total of four wings. The wings are symmetrically arranged on each side of the mosquito's thorax. The buzzing sound associated with mosquitoes is a byproduct of the wing beats. Males, in particular, are known for producing distinct sounds during flight, which can play a role in mate attraction.

4: Legs

Mosquitoes, like most insects, have six legs. These legs are arranged in pairs on the thorax, the middle section of the mosquito's body. The legs are jointed and segmented, allowing for flexibility and a wide range of movement. The primary function of mosquito legs is locomotion. Mosquitoes use their legs to walk, jump, and land on surfaces.

5: Cercus

Female mosquitoes have specialized structures called cercal plates, which are involved in the mating process. Cercal plates play a role in detecting wing beats and other cues associated with mating behavior. The cerci on mosquitoes also function in laying eggs. 

6: Scutellum

The scutellum is an essential component of the mosquito's thorax, serving multiple functions related to flight and structural support. Its unique characteristics make it a valuable feature for entomologists and researchers studying mosquito anatomy, taxonomy, and behavior.

7: Compound Eye

The compound eye of a mosquito is a complex and highly specialized sensory organ that plays a crucial role in the insect's visual perception and behavior. The compound eye is composed of numerous tiny units called ommatidia. Each ommatidium consists of a lens, photoreceptor cells, and supporting structures. The overall structure resembles a rounded or hemispherical shape, covering a significant portion of the mosquito's head.
