Section I: Recognition and Identification of Phlebotomine Sand Flies
Let's face it. They're tiny and difficult.
Identifying males is slightly easier than identifying females because the terminal genitalia (terminalia) located at the end of the abdomen have external anatomical characters that can generally be used to separate species. If you see any appendages (right), it's a male. However, a stereomicroscope with approximately 100x magnification is needed.
