The Banana Skipper, Erionota thrax thrax (L.)

Has the same habits of E.torus, though considerably is to be less frequently encountered in the wild because of its crepuscular habits. From observation, less than 20% of collected pupa from infected cultivated and wild banana eclosed E. thrax compared to E. torus. Sometimes referred to as "Acute Banana Skipper" because of the acute termen (straight) in comparison to E. torus.

The Chinese Banana Skipper, Erionota torus (Evans)

The Banana Skippers are moderately common in localities where its foodplant banana is cultivated or growing wild. The larvae can easily be singled out in tell-tale rolled banana leaves. They sometimes enter houses in the evening, attracted to the lights of the house, being crespuscular in habits. In Malaysia, 2 species of closely ressembling Erionota exist in the same localities and E. torus can be differentiated from E. thrax by its squarish spot 3 of the forewing (see pix below). From observations, the pupas tend to be more readily found in the wetter months from Nov - Feb (growth spurts of wild bananas due to rain?)

 Above photos of the final instar caterpillar, covered with a white waxy substance akin to the white powder under a clean banana leaf. This caterpillar was taken from an infected wild banana plant along a forested path @ 600M

the pupa in the rolled-up banana leaf...

The pupa eclosed in the early hours of the morning...

Notice the rather squarish spot 3 on the forewing

It was released into the garden under a Calathea shrub: 01 Nov 2014 @ 8:15

Above pix of infested banana leaves - the sides are "torn away" to form the cigar-like rolled-up nest of the caterpillars
