Butterfly Sightings in SG (by Peacock Royal)

[Peacock Royal]

Created this thread to record/document some butterfly sightings during my weekly outings.

1. Euploea tulliolus ledereri (Dwarf Crow)


2. Arhopala myrzala lammas (The Malayan Oakblue)


3a. Pelopidas agna agna (The Bengel Swift)


3b


4. Telicota augias augias?


5. Telicota besta bina?

[Psyche]

3. Borbo cinnara.
There is no HW cellspot & the colouration & markings are that of B. cinnara.

4. Female Telicota linna.
Despite being worn the veins across the HW band are not darkened.

The female T. augias is more orange & the HW band has the veins lightly dark-dusted.

It has been quite a long time since my last post here - because I have not got something "interesting" to post.
Here are four species I have not encountered for a long time.

9. Likely to be the Nacaduba pavana singapura


10. Nacaduba berenice icena ?


11. Likely to be the Jamides elpis pseudelpis


12. Logania marmorata damis


13. Abisara geza niya

Post 3.

8 a, b, & c. Potanthus mingo.
P. mingo is probably not a rare species but easily confused with trachala or ganda.

Potanthus mingo ;more yellow ;
FW spot 4 & 5 with overlap to spot 3 (variably to spot 6 above), spot 2 & 3 wider (ie more rectangular) ,their outer margins not strongly concave;
HW upper spot (4 + 5) of band not strongly projected out; Abdominal end black banded.

Potanthus trachala. ; darker orange.
FW spot 4 & 5 without overlap to the spots above & below. spot 2 & 3 quadrate with strongly concave outer margins; UnF spots spiky.

Potanthus ;deeper orange;
FW spot 4 & 5 with partial overlap with spot 3, little with spot 6 ;spots with straight margins.

9. Nacaduba hermus.
Dark striae weak ; HW with submarginal spots 4 & 5 close to the postdiscal band (ie in space 4 & 5)HW black spot with metallic scales.

N. pavana ;Dark striae always strong; black spot with metallic scales.

1o Nacaduba berenice.
This male is unusual in having broader submarginal spots.
FW margin rounded; submarginal spots with irregular pointy margins.Dark striae always strong in the male.FW postdiscal band often dislocated or kinked in the middle.

N. kurava; male with rather straight FW margins; submarginal spots with rounded margin; postdiscal band intact typically straight.HW spot 6 blocky.
Dark striae weak in the male.

11. Jamides alecto ;white striae broad & thicker in lower part of FW & outer part of HW.


J. elpis; White striae rather thin on both wings.

Dr Seow, do you think #9 is N. pendleburyi? I chanced upon this photo by Richard recently which i'm very certain is N. pendleburyi and it looks very similar to Federick's.

What do you think?

Federick no. 9 is Nacaduba hermus for two reasons.
1. HW postdiscal & submarginal spots in space 4 & 5 very close ,almost touching.
2. HW tornal black spot with metallic scales.


N. pendleburyi & sanaya shares the following features.
HW postdiscal band & submarginal spots in separated by at least 1/2 the width of the postdiscal band.

The males of the two are seperated thus.
N. pendleburyi FW border increases at apex.
N. sanaya FW border a thread throughout.

No separation for the female.

N. sanaya almost always have a dislocation of the FW postdiscal at vein 6 (sometimes 5).

C&P4 shows a N. pendleburyi with very narrow submarginals & HW spot 6 a chevron (or arrowhead); FW band not dislocated.

I have been unable to locate previous N. pendleburyi image.
N. pendleburyi do not have HW tornal black spot with metallic scales.

N. sanaya is very variable in the separation of the HW postdiscal & submarginals.

India have neither subperusia or pendleburyi.
The metallic scalings may be meagre in some forms esp. dsf. of N hermus.

Richard's shot is hard to say, for it could also be N. sanaya or hermus though the metallic scales are just a few.
The submarginals are narrow as in pendleburyi but the HW submarginal spot 6 is not a chevron (V-shape).

I would need to locate some correct shots of N. pendleburyi for comparison,

Thanks Dr Seow. I was misled by the wing shape. The forewings are streched forward so they appear more elongated.

I didn't think this was sanaya because the post-discal on the forewing is curved and the distance between the subbasal and discal striae on the hindwing is too wide for sanaya. The striae are also thinner than in sanaya

I am not sure if you have C&P4.
Nacaduba key.

Line 10 (13) UnH with inner submarginal & outer postdiscal striae in space 4 & 5 nearly touching ........ N. hermus, subperusia lysa.

Alternative line 13. UnH with the inner submarginal & outer postdiscal striae separated by at least 1/2 the width of the postdiscal band. .....N. pendleburyi, solta, subperusia intricata(montane) and sanaya.


That is, both N. pendleburyi & sanaya have the postdiscal & submarginal fasciae well separated, whereas N. hermus & subperusia lysa have them close & nearly touching.

There is no problem with Federick's shot as the two fasciae are almost touching plus the metallic scales on the black spot is vitually certain to be N. hermus.

The problem with Richard's pic is that the separation is just about 1/2 the width(of the postdiscal) in space 4 & less in space 5.
The unbroken FW postdiscal band & neater spots suggest it is probably N. pendleburyi.
This is a male & the definitive diagnosis is the UpF border which increases at the apex in pendleburyi , but remains uniformly narrow in sanaya.

As you can see in N. sanaya the separation of the postdiscal & the submarginal varies widely ,some well apart & some close as in this (Richard's) example.
N. sanaya seem to have margins somewhat irregular & not neatly aligned as in pendleburyi.
The FW postdiscal band in sanaya is almost always dislocated usually at vein 6 (but not in all instances).

Past pix of N. sanaya need to be scrutinized carefully .
The straighter FW margin of the male N. pendleburyi looks to be a valid point.
