Studying caddisflies in Thailand
Up to date, at least 1,000 caddisflies
species had been reported in
Thailand.
Prommi (2007) reported 15 genera,
49 caddisflies species in Narathiwat
Province.
However, rare reported caddisflies
species in Narathiwat !

Identified to species level
Specimens were preserved
in absolute ethanol. Male
genitalia were cleared in
hot 10% KOH and
identified to species level
through a microscope
using keys and an atlas.
