ID help needed

Thank you Dr.Seow

Hi Dr.Seow,

Is this Miletus symethus petronius?

Attachment 28516

Thank you.

Post 62.

Probably Miletus gopara female. Correction: Miletus biggsii.

M. symethus.
This can be eliminated because the HW postdiscal spots are crescent with rounded outer margins.
Apices of FW & HW are whitish shaded.
Male & female.

M. biggsii.
Underside more uniform & HW postdiscal spots are blocky.
UnF cellend mark is a thin line.
Male & female.

M. gopara.
Underside with uneven shading & whitish apices as in symethus.
HW postdiscal spots part crescent & part blocky. FW postdiscal spots in line.
UnF cellend mark broad band-like.
Female with a variable 'tail' at vein 4.

Although the tail is not that prominent in thisfemale, comparing the FW cellend mark between gopara & biggsii seem to suggest the former.(Use the Yutaka images.)


TlSeow: cheers.

Thank you Dr.Seow,

I have enlarged the image, hope it's clearer.

Dear Dr.Seow,

I can't id this individual. Could you help?

Thank you.

63-64.
Best left as Miletus biggsii female.

The tail is not long enough to be that of M. gopara female.
The FW postdiscal band's spot 6 is dislocated.
In M. gopara this is typically in line. (Varies.)

Id features are often vague & variable in Miletus.


No. 65.
Female Hypolimnas bolina bolina.
The female is very variable.



TL Seow: Cheers.

Thank you.

The female beroe is very similar & confused with the female of Ionolyce helicon.
In I. helicon HW submarginal spot 3 (above the black spot 2) is sharply pointed.
In the female of N. beroe this spot is rounded.
