These i think are all female N. berenice icena

These first two are the same individual

Post 1.
Concur it is N. kurava male.

Post 2.
1 is N. berenice female /Upperside pale blue.

2. is a bit dificult.
It could be N. calauria as the submarginal spots 4 & 5 are pointed on both wings.
An upperside shot may help.
The variation in N. calauria here is not known.

Tentatively I will leave it as N. berenice female.

TL Seow:Cheers.

Thx for the confirmation Dr Seow. Unfortunately that is the only view that i have of the 2nd individual.
I don't know if berenice and calauria are found in the same localities

Here's two shots of what i think is berenice from the curvature of the post-discal band on the forewing.

I have one or two which i think might be calauria. I find berenice and calauria very difficult to separate

Post 5.
1 pair N. berenice male L, female R.

2 male. This is very difficult.
The pointed submarginal spots 4 & 5 says calauria, but the broken postdiscal says berenice.
It may be a hybrid.
It is difficult to compare with images from other region eg in Australia berenice have all the submarginals sharp-pointed.

Here are some examples from Singapore.

As none of the definitive male or female have FW spot 4 & 5 sharply pointed, it strongly suggest your no. 2 should be a male N. calauria variant in which the postdiscal is dislocated in the middle.


N. calauria.

Note in both male & female N. calauria FW submarginal spots 4 & 5 always have a very sharp point.

Females. N. kurava. FW postdiscal almost always straight & submarginals with rounded margins.

Thanks Dr Seow for your insights. I'd hate to complicate matters, but could it be possible that berenice might occasionally have more pointed striae in spaces 4 and 5 like this?

Here are two more- the first i'm very certain is a female calauria based on the points discussed. The second is a male and i'm less certain but i think it's a male calauria even though striae 4 and 5 are less pointed. This was the only decent shot i could manage:/
