Dear Dr Seow,
May I know if both images below are Common Caerulean? Took at Ulu Sembawang.
Thank you.

Yes. Both are Jamides celeno male.

Jamides celeno is very common & the male often has rounded FW like the female.

Male upperside with a FW black border that increases in width to the apex.
Underside with margins of bands mostly straight .
Female with upperside HW space 6 & 7 dark shaded.

The 2nd similar species is very rare but easily confused.
Jamides pura.
Male upperside FW with black border a thread.
Underside HW black tornal spot more often with long silvery side bars.
Female HW upperside only space 7 dark-shaded.
Female underside FW submarginal band lunulate ie the spots are moon-shaped.

One valid observation.
Note male upperside FW black border is virtually a thread.

There used to be a female image showing all the Fw submarginal spots lunulate (moon-shaped) now lost.


TL Seow; Cheers.
