The body part used for identification of mosquitoes is:

• A. The wing scale
• B. The antenna
• C. The proboscis
• D. The tarsus, the foot segment of an insect leg

Answer: (D)

Identifying mosquitoes relies on distinctive features that show up on specific body parts, and the tarsus—the last segments of the leg—provides reliable, observable clues. The color patterns and banding on the tarsal segments are often species- or genus-specific, making this part a practical and quick way to differentiate mosquitoes in the field or with basic lab work. While wing scales, antennae, and the proboscis can also offer useful information, they are either more variable, harder to observe clearly on routine samples, or require closer inspection. So examining the tarsus gives a straightforward, dependable cue for identification.
