On the head area there is a proboscis, antenna, maxillary palpus, and clype. On the thorax area there is the scutum, and at the end of the thorax is the scutellum. Proboscis in males is longer (0.76 ± 0.04 mm) than in females (0.53 ± 0.06 mm) but only in females the structure is formed to suck blood while males only suck nectar. The antennae in males are longer (0.57 ± 0.03 mm) and also have denser hair than females (0.52 ± 0.07 mm) [101–103].
