https://www.inaturalist.org/observations/202131561

Not sure if the subspecies name of "laruta" is associated with Larut district where Bukit Larut is located. That got me wondering if the dominant species in Bukit Larut is Y.pitane laruta????

I did not get an upperside photo but saw this upperside taken by Gan CW took in Bukit Larut in 2017 that is id as Y.pita. I looked at CP5 photo plate, my untrained eyes cannot decide if it is Y.pita or Y.pitane, hahaha.

Male Nacaduba kurava.
FW margin straighter; submarginal spots with rounded margins; FW postdiscal band usually fairly straight.
Dark striae within the postdiscal bands weak ,may be patchy.
Male.

Nacaduba berenice.
Fw margin more rounded; submaarginal spots of irregular shapes; postdiscal band almost always broken ,often in the middle.
Dark striae within all bands are usually strong & well-developed.
Male.

#3. https://www.inaturalist.org/observations/202260899
The markings are as for Arhopala pseudomuta & it is likely this species.

Euploea crameri bremeri.
FW apex with 2 large & 2 much smaller spots.
Fwith a full series of submarginal white spots.
https://www.butterflycircle.com/chec...20-%20Loke.jpg

The form of E. midamus in your area does not have apical white FW spots.
In India E. midamus is brilliantly blue but ssp. chloe in P. Malaysia is only darkly blue basally.
https://wingscales.com/Nymphalidae/E...-midamus-chloe

South of selangor, white spots start to appear on the FW apex, and the blue becomes more obscure.
The form in Singapore closely resembles E. crameri but the apical spots are more uniform, & the FW submarginal spots are incomplete.

Abisara saturata.

The three similar species may be Ided thus.
Males have the HW tail at vein 4 rounded.

Abisara kausambi.

https://thaibutterflies.com/Butterfl...sara-kausambi/

Abisara saturata.
HW with the two tornal black spots often sharp-pointed.
Male without white shadings on the FW.
Female with the FW white patch merging with the inner submarginal white line.

This appear to be large, with the orange band very broad.
Of the similar species 4 are similar.

Ancistroides (Kerana) armatus is very large ,FW 23-27mm, orange band with a strong notch in the upper third.
https://yutaka.it-n.jp/hes/91570001.html

Korithaialos rubcula have long palpi not seen here.FW 14-18mm.
https://yutaka.it-n.jp/hes/91510001.html

Koruthaialos sindu.fw 15-19MM. orange band with a outer mid-margin notch.
https://yutaka.it-n.jp/hes/91530001.html

The 4th K. frena is similar to sindu but with broader orange band without an outer margin notch.
It is larger Fw 22mm. & it appear to be this species. It is a hill insect.


#8. https://www.inaturalist.org/observations/202140606
Iambrix salsala.
Only this species have spotting like this.
Some spot may be missing. eg

#10 https://www.inaturalist.org/observations/202131965
Miletus gigantes.
Only two species have females which are largely whitish.
https://yutaka.it-n.jp/lyc2/80275001.html

The other M. symethheus is more bluish grey on the HW.

Yasoda pitane laruta.
Both sexes have a black fascia on UpH & the wingbases are not darkened.
Underside brown orange with white scales in submarginal zone of HW (Fleming.).
Very rare.
BTW laruta is larut latinised ,ie new Latin. All scientific names are written in Latin. New latin words are constantly coined by scientists in taxonomic nomemclature.

Male Potanthus trachala.

Medium FW 15mm.
Abdomen with a black band at the end.

Male Arhopala agrata.

Arhopala agrata have the arrangement of the markings as in the cleander group & often is mistaken for a member of the smaller-sized alea subgroup.
It is distinctive in that spot 9 (topmost spot )of the FW postdiscal band is obsolete or nearly so.

Curetis santana & bulis.

These two can be quite difficult in fieldshots.
cURETTT.png


Curetis santana.
UpH space 7 at least half orange (very difficult as it is always hidden in fleldshot.
HW less heavily black in the basal & tornal area.
UnH postdiscal spot 6 & 7 in line.
Submarginal spot 6 & 7 out of line ,dislocated.
https://yutaka.it-n.jp/lyc3/84050010.html

https://thaibutterflies.com/Butterfl...retis-santana/



Curetis bulis.
Male UpH with space 7 at least half black.
HW basally & tornal area heavily black.
UnH postdiscal spot 6 tuck under spot 7 which is often crecentic.
Submarginal spots 6 & 7aligned end to end.

#14.https://www.inaturalist.org/observations/201694982
There are definitely more than one individual eg pic 5 & 7 show different image, one with torn wings.


Pic 6, 7, & 8 looks to be C. santana.
https://inaturalist-open-data.s3.ama...592/large.jpeg
https://inaturalist-open-data.s3.ama...599/large.jpeg
https://inaturalist-open-data.s3.ama...608/large.jpeg

The rest looks right for C. bulis.



#15 https://www.inaturalist.org/observations/201696252
These appear correct for C. santana.

[Psyche]

#16.https://www.inaturalist.org/observations/201685237
#17.https://www.inaturalist.org/observations/201692407

likely males Baoris penicillata chapmani.
It is hard to discern any features but spots are not visible.

B. penicillata have much reduced spots, & a profile view appear spotless.
https://yutaka.it-n.jp/hes/93230020.html
Most authors consider taxon unicolor to be a subspecies in which all the spots are lost.
https://yutaka.it-n.jp/hes/93230010.html
A profile shot looks matching.

Ge geta have very long curvy antennal ends.

Uncertain.
Likely female Isma species probably I. iapis.
https://yutaka.it-n.jp/hes/91880001.html
The male has diffuse dark spots UnH.
The female is less obvious.
Mating pair, female on the right.
