Abstract
Larva and pupa of the Oriental Chaeridiona thailandica Kimoto are described, figured in detail and compared with the recently described immatures of Ch. picea Baly. Ch. thailandica larvae mine in leaves of gingers belonging to Zingiber and Boesenbergia and pupate in the mid-ribs of leaves. The larvae and pupae possess plastron-bearing spiracular gills allowing respiration in water when temporarily submerged after heavy rain.References
