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 commonly known as bee fly mainly known from southern and eastern oriental region and range into palearctic in eastern China[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, Vietnam [4][6].

Description

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

Male

Body length 3.5-6.0 mm, wing length 5-7 mm. Black head, 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. Long slender legs are dark brown with short hairs. Wings are dark brown to light brown. Abdomen black and dorsal side with dense silvery white scales but exhibit variation between individuals[4].

Female

Body length 4-6 mm, wing length 5-7 mm. black head, sides of antenna with long white scales and compound eyes are dichoptic. Proboscis black and nearly three times longer than head. Legs and wings are similar to male. Abdomen of the female is black and dorsal side with red to orange scales and shows no variations among individuals[4].
