I found another caterpillar on the same patch of Lalang recently and and the adult looks like a T.besta (male) but the caterpillar does not look like the T.besta I have raised previously (no black cap at tail and head looks like T.aguis).
Is this a T.besta? Photo taken less than 3 hours after eclosion.
