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.

Yes, this is typical E. acroleuca.
TL Seow: Cheers.
Last week I found 3 pupae on my banana.
This is E.thrax as the forewing termen is straight.
BananaSkipper 201907110044.JPG
Would the termen for these two be convex enough for them to be E.torus?

Perfect. You have E. thrax & 2 E. torus.
Strangely they are all females. (antennal club half white).
TL Seow: Cheers.
Thank you.
