Delias pasithoe parthenope

[Sky Blue]

This species already gone extinct in SG? Realized that it's in the checklist but never encounter them :thinking:

Erm... that isn't Delias pasithoe, BJ. What you shot is the Red Spot Sawtooth. :)

In the field of animal ecology, I believe a period of 50 years should pass without a sighting of the species before it is placed on the 'extinct' list. Perhaps Jac can shed some light on the convention and methodology.

There are other species in the Singapore checklist for which we have at least a voucher specimen, but have not seen them for the period after 1995 (when I started the surveys). Most of these species were surveyed/captured by Steven Neo in the early 90's.


Delias pasithoe parthenope (last seen at Mandai area)
Elymnias penanga penanga (last seen on Pulau Ubin)
Mycalesis perseiodes perseiodes
Hypolimnas misippus misippus (last seen at Mandai area)
Castalius rosimon rosimon (last seen at Mandai area)
Arhopala aedias agnis (last seen at MacRitchie area)
Arhopala major major (ID not certain)
Jacoona anasuja anasuja (last seen at Mandai area - near reservoir edge)All the rest of the species were recorded post-1995, and there is at least a voucher specimen for all of them, with the exception of Ancema blanka blanka which was ID'ed from the shot that Federick and I took at TBHP.

:embrass: thx for the correction.

These species could just like the harlequin hiding somewhere in the wooded areas :thinking:

Yup. New species to the Singapore Checklist are always waiting to be discovered. :) Just like that female Euthalia merta merta that appeared in front of the group of us, hung around awhile just to be shot, and then disappeared as quickly as it had appeared. First time I've seen a female.

More likely to discover new species in the north/western parts of Singapore... and of course, Ubin and Tekong. ;-)
