Yes, they are all E. hiraca.
1. Antennal club all white above (less extensive in the female) .Half white in thrax/torus.
2. FW apex white extend across to termen ( costa only in torus; may extend to termen in thrax.
3. HW band very narrow in upper half (variable) ;relatively broad throughout in the other two.
4. Upperside FW apex with white patch in male ; obscure or absent in the female.

The underside of E. thrax can look similar but the antennal white is only on the basal half of the club.
Two examples of E. thrax showing the different apical white . Note white of antennal club.

Is this E.torus? The caterpillar was found on Ptychosperma macarthurii (MacArthur Palm).

E. hiraca male. Upperside FW apex white edged; antennal club largely white above ; Underside HW band strongly narrowed in upper part.

Some examples of E, hiraca especially females closely resembles E. thrax/torus.

E. torus ;broad shape; smaller white patch on club; FW no white edge; HW band not markedly constricted in upper half.

Thanks Dr Seow. So E.hiraca also feed on Ptychosperma macarthurii (MacArthur Palm).
