Bagworm Moth

Unidentified Psychidae. This kind of moth is very difficult to identify. Wikipedia explains that, because the "case" or "Bag" is always unique to each species, the best way to identify a Bagworm Moth is by its case. I have to admit, I have never managed to identify any of the several specimens I have posted on Project Noah. When I look in the Psychidae section of Philippine Lepidoptera and see how few have been identified by their experts, I can see the magnitude of the problem.
