1.https://www.inaturalist.org/observations/198051521

There appear to be two species & perhaps several individuals.

Pix 2, 3, 4, 5, & 6 appear to be Euploea doubledayi .(Probably E. doubledayi occur in Penang after all.)
https://inaturalist-open-data.s3.ama...433/large.jpeg
https://inaturalist-open-data.s3.ama...435/large.jpeg
https://inaturalist-open-data.s3.ama...434/large.jpeg
https://inaturalist-open-data.s3.ama...436/large.jpeg
https://inaturalist-open-data.s3.ama...438/large.jpeg

The 2nd pic here shows a narrow brand & the HW with longer stripe-like spots.
The dull blue-black FW sheen indicate it should be E. doubledayii.
The UpF of E. eyndhovii is dark brown.

https://yutaka.it-n.jp/dan/30660010.html


Pix 1, 7, 8, 9, 10, & 11.should be Euploea algea.
The HW submarginal spots are shorter bars, longest at the tornus & tapers upwards.
The upperside have a deep dark blue brilliance.
https://yutaka.it-n.jp/dan/30600010.html
The male brand is broad & long.

https://eol.org/pages/46799999

Other similar species have the HW submarginal spots more uniform in size.

2. https://www.inaturalist.org/observations/198112757

Uncertain. It does look like a female Rapala iarbus but the diffuse orange & the incurved HW postdiscal band suggest a member in the Tajuria group.


3. https://www.inaturalist.org/observations/198069467

Female Allotinus horsfieldii

HW postdiscal spot 6 under 7 close to spot 7.
Female with longer broad-based teeth.
Male & female.

Allotinus unicolor.
HW spot 6 rounded & set well inside of spot 7.
Female with short broad teeth.

6. https://www.inaturalist.org/observations/198051271

Too blurry. Looks most like A. major.


7. https://www.inaturalist.org/observations/198051261

Arhopala epimuta.
There is just enough visibility in pix 4 & 5 to see the pattern of HW spots 5, 6, & 7.

8. https://www.inaturalist.org/observations/197990775

Female Athyma nefte.



The female of the two species differ in the shape of the FW cell-bar, the tip in nefte being sinuous.

Female A. nefte.

Female A. reta.

Should be right as Rapala iarbus .(There is just no other match.)

The sharper FWs just a male, but this is likely a perspective distortion.
The wider dark border on the FW margin(termen0)& the colour indicate a female.

What appear to be curved black marks on the HWs are deep shadows.

10. https://www.inaturalist.org/observations/197839011

Miletus. Too worn to Id.

11. https://www.inaturalist.org/observations/197838984

Probably Parnara ganga.
have the large spots as seen in P. ganga.
However a small spot 6 is present.
Eliot with another author state HW spot 6 is usually absent in P. ganga & present P. apostata.
HW spots can vary in both species.
This looks more towards P. ganga.

P. apostata .The upperside is almost black.
https://yutaka.it-n.jp/hes/93020001.html
https://1.bp.blogspot.com/-R1LW7DbcO...0/DSC_0338.JPG

P. bada have UnH spots usually small & separated.

a. Female T. ohara.

15. https://www.inaturalist.org/observations/197521762

Male Euploea core graminifera.
Luckily the FW is raised high enough to reveal the large oval spot in space 2.

Euploea core.
FW with a thin brand in space 1b.
FW subapical spots smaller & well separated.
UnF with a spot in space 2 which is relatively large & oval.
https://yutaka.it-n.jp/dan/30580030.html

Euploe crameri
UpF with the subapical spots in space 4 & 5 large so the spots are nearly contiguous.
Unf with a small spot in space 2 which is rounded or absent.
https://yutaka.it-n.jp/dan/30520010.html



16. https://www.inaturalist.org/observations/197184899

Female Pelopidas mathias.
This is fairly typical.
Note spot in HW cell & strong grey tinge of the wings.
