2. Euthalia merta merta male.
The submarginal arrowheads especially on the HW point outwards.
This is the only species like that.

Thanks so much Dr. Seow.

Update: I just eceived another id feedback that #1 could be Euploea klugii erichsonii? What do you think? Unlikely? Thanks.

Update 2: I checked my past Euploea observation where someone mentioned that there are post discal hindwing spots for E.core graminifera and none for E.klugii erichsonii, is this right?

Correction Euploea klugii erichsoni.
https://yutaka.it-n.jp/dan/30780010.html

I did check out this but could not match the pattern.


Euploea klugii.
HW with the inner series of submarginal spots becoming more separate upwards.
Underside HW without discal (central) white spots.

The word discal or postdiscal denote the position & can varies according to the author.
Euploea core always have a few white spots in the discal (central) area.

Postdiscal means the spots away from the central area , & towards the margin.

TL Seow; Cheers.
