View Full Version : Three atypical butterflies?

Further digging around in my backlog brings up three butterflies (four images) that don't match anything typical that they resemble.

The first, Image 1, is a Faunis sp, from Sri Phang-nga (s Thailand). The obvious choice would be Common Faun Faunis canens arcesilas. However, several features do not look right. The overall rather dark (deep chocolate brown) colouration looks more reminiscent of Broad-striped Faun F. kirata. Also the post-discal band on the hindwing is rather broad for F. canens. (All my other images of canens have narrower bands). However I would expect kirata to show a series of whiter spots across both wings, whereas these are slightly orange off-white as in canens. A confusing individual. Kirata is recorded from s Thailand, but very rare.

The Images 2 and 3 are the same butterfly, taken on Doi Inthanon n. Thailand. My initial thoughts were Common Fourring Y. huebneri, but I have no images of this species without large ocelli on the underwing. Even in the dry-season. These two images were taken in February. Does this species sometimes lack spots in the dry season. The other possibility that comes to mind is Y. akbar?

Image 4 is an odd-looking Threering sp. presumably Y. confuse, but I have never seen Y. confuse in Thailand with the upper ocellus of the hindwing smaller than the ocellus in the upperwing. All my images show the hindwing ocellus usually significantly larger. I also note a double dark band across the upper wing discal area, which does not look typical. Image taken in Chiang Dao. I have no ideas on this image and suggestions would be appreciated.

Many thanks

1. Faunis canens.Same have broader dark bands ,female I think.

2& 3 Very difficult dsf.
Note underside HW outer band sharply angled.
The only species I see with a similar band is Ypthima affectata.Range Assam to N. Vietnam.
Correction: Unlikely to be Y affectata as these from India do not show any angulated fascia.

4. Likely Ypthima confusa.Uemura mention HW apical spot much larger than spot 2 ,but nothing about comparing to the FW spot.

In Ypthima watsoni. HW apical & spot 2 are about equal.
This is probably Y. watsoni rather than norma.

Y. norma :smaller spots apical & spot 2 subequal ;small species.

Many thanks. I figured dry seasonal forms are just nightmares.
Thanks for confirming the F. canens.

2 & 3.

The presence of spots 2 & 3 on the upperside HW should indicate it is a Five-ring.
The commonest is Y. baldus & is the most likely.

Of the others you mentioned Y. huebneri have no dark fascia.

Y. akbar.
