Characteristics

• Udaya are small mosquitoes with conspicuous patches of silver scales on the head, thoracic pleura and abdominal terga. The adults are characterised by a spoon-shaped patch of broad overlapping silver scales that separates the eyes and extends to the antennal pedicels, absence of acrostichal setae, a patch of broad silver scales on the antepronotum that separates the setae into two groups, absence of scales on the postpronotum and postspiracular area, broad overlapping silver scales on the paratergite and the alula of the wing has broad flat scales on the dorsal margin. Larvae are similar to species of the Aedes genus-group, Heizmannia and Zeugnomyia, but are distinguished by the following characters: setae 4,5,6-C placed far forward on the head and seta 7-C inserted far from the lateral margin of the dorsal apotome (distinctions from Aedes genus-group), comb with 10 or fewer scales in a single row (distinction from Heizmannia) and saddle of abdominal segment X without strongly developed spines along the posterior margin (distinction from Zeugnomyia). See Aedini.

Bionomics

• Very little is known about the bionomics of Udaya. Larvae of Ud. argyrurus and Ud. subsimilis have been collected from bamboo. Females of Ud. argyrurus have been found on occasion in catches of biting flies.

Medical

• Udaya species are of no medical or economic importance to humans.
