What about this - E.torus or E.hiraca? This is a wild specimen recorded yesterday.

The three species can be very similar.
It had been stated that all records of Erionota on palms are probably E. acroleuca (hiraca) & E. torus & thrax probably feed only on Musa (banana).
Past misidentification have cause all the confusion.
The sdame authors state that palm leaves are unsuitable for the leaf rolling habit of E thrax & torus.
However, your post 1 female looks typically E. torus & may be a first record on palm.
If you can rear a pair it should clear all doubts regarding the species & hostplant.

Thanks Dr Seow. I will look out for more caterpillars.
Yes, the leaf shelter is different from the E.hiraca that I have raised before.
Found and raised two caterpillars feeding on MacAuthur Palm. Think they are E.acroleuca.
