Hi Dr Seow,
Would require some help in identifying this one. Is it a E.acroleuca apicalis or E. torus?
Thank you.

TL Seow :Cheers.
Thank you Dr Seow for the detailed explanations and comparisons!
Hi Dr Seow,
I shot this Erionota, the markings do resemble E.acroleuca, however the size was much larger than usual (estimated FW size 30+mm). I have raised a couple E.acroleuca before but they were never quite this large. Would like to hear your inputs.

Females of all three species have the antennal club 1/2 white above.
TL Seow: Cheers.
Thank you Dr Seow, did not know they could get this large, very cool to see in the field!
Another thing to note.
As far as it is currently known, E. acroleuca only feeds on palms, while E. thrax & torus feed on Banana (Musa sp.)
Mis-identification in the past was said to be the cause of palms included in the hostplants of E. thrax & torus.
TL Seow: Cheers.
Hi Dr Seow,
Is this E. torus (female)? It was raised on banana leaves.

Yes. E. torus. FW margin is convex .A female from the abdominal end.
TL Seow: Cheers.
Thank you Dr Seow!
Hi Dr Seow,
I raised another Erionota sp. on banana leaves, but from certain photos the termen looks straight, in others it looks a little convex. So I am a little conflicted if it is either E. thrax and E. torus. Would like to hear your opinion on this. Thank you!
*Both are the same individual

Female Erionota torus.
It can often be difficult to judge from photos because of the angle of the shots.
It is always good to have several views..
Pic 2 obviously indicate E. torus.
E. torus is probably more common in Singapore.
