Celastrina argiolus or Udara dilecta

[DaveChiangMai]

From Doi Phu Kha n Thailand. Two images, same individual. I am having a hard time trying to differentiate between C. argiolus and U. dilecta. The hindwing post discal spot in 1d is broken into two distinct spots which would seem to rule out dilecta.

However, a similar looking individual, discussed here, is U. dilecta.

The upperside show it is Celastrina argiolus iynteana.

In the other thread I have some reservation with the ID of female Udara dilecta since the wingshape appear to be wrong & it is also too dark, but did not check it up .
Celastrina argiolus is a widespread temperate species with varying appearance.


Celastrina argiolus iynteana female.
FW rounded ( much like Eurema ada.) FW lower submarginal spots more strongly chevron.
