Taxonomy

Euchariomyia dives is described by French entomologist Jacques-Marie-Frangile Bigot in 1888.[3] This species is highly variable in appearance and earlier placed in four separate species. However, further study revealed that they are all belongs to one species.[4]

Distribution

Euchariomyia dives is mainly known from southern and eastern Asia.[5] They are reported from Burma, China (Beijing, Guangxi, Shandong), India (Kerala, Orissa, Tamil Nadu, Uttar Pradesh), Indonesia (Java, Sumatra), Laos, Malaysia (Kelantan, Penang), Sri Lanka, Thailand, and Vietnam.[4][6]

Description

They are small in size (4-6 mm), head with a long proboscis, iridescent wings, and long, slender legs. There are conspicuous silvery tufts of scale-like hairs on the head, thorax, and abdomen. The legs are dark brown with short hairs. The wings are dark brown to light brown.[4][5]

Male

The body length 3.5-6.0 mm and the wing length 5-7 mm. It has a black head and a face with long sparse black hairs. They have long white scales just above antennae and compound eyes are holoptic. Proboscis extend well beyond oral margin up to 8 times head length. Thorax is black and grey and the surface covered with a fine yellow dust, like pollen except pronotum. The abdomen is black and the dorsal side has dense, silvery white scales, but exhibits variation between individuals.[4]

Female

The body length is 4-6 mm and the wing length is 5-7 mm. It has aack head, sides of antenna with long white scales and compound eyes are dichoptic. The proboscis is black and nearly three times longer than head. The abdomen of the female is black and the dorsal side has red to orange scales, showing little variation among individuals.[4]
