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.
Male Erionota acroleuca (= hiraca )
Underside HW dark contrasted ,speckled .The upper half narrowing of the band less obvious.
What about this - E.torus or E.hiraca? This is a wild specimen recorded yesterday.
