keep rearing until you get the adult.  Most micro moths in HK have little or no ecological information available other than for the adults.

Reply #1 banderbear's post

probably a species of Helcystogramma (at least 6 species in HK)
Gelechiidae, Dichomeridinae (well done for getting the right family )

see Helcystogramma triangulella / triangulellum on the Moths of Japan website - http://www.jpmoth.org/Gelechiida ... _triannulellum.html

And thus explains one of the needs to rear through to the adult form (not to mention
obtaining an ID on the specific larval food plant (=>HK Herbarium) which you seem to have done
quite well, elevation, lat & longitude, etc. !

both larvae victims to parasitic flies, sorry

they stopped feeding at 15mm and sealed off in leaf chamber (to begin pupation?) then the parasitic fly larva emerge
