Stichophthalma eamesi

Post by daveuk »

A very variable species from Viet-Nam. Unknown to me until about fifteen years ago. Some place this as subspecies of S.louisa.

I was just about to ask if you could photograph S. camadeva or S. cambodia if you have them.

*I have never achieved getting any of the Jungle Queen species..

Yes I have both those species. Will try to find existing photos or take new ones & post. S camedeva is a personal favourite. From being a butterfly that was freely available in the 1980s it is virtually unobtainable now apart from those in old collections. It was the first species I ever saw illustrated & later for real. It has remained a firm favourite of mine ever since

Indeed, I have searched long and hard for S. camadeva in some old collections which I have perused over these last 25 years. Found only two of (substandard) quality which I had to pass on....

It too remains the first Stichopthalma species which I ever saw illustrated (at around the age of seven). An illustration of it was present in the "How and Why wonder book" of Butterflies and Moths --- circa mid-1960s.

Found some old pictures of setting stages of a female S camadeva I did. Taken with a flash so the wings appear more lavender blue that they do in natural daylight

Hi Dave,
This is another recent "Stich" acquisition. It looked to
be a fine specimen but, like (1/2) the things I find
in old collections this one needed a re-spread to suit me.

Anyway, in looking up this thread due to the name on the label
it bears no resemblance to your S. eamesi specimens.

So, what do I have here ? Is it a good one given the locality ?
If you or (anyone else ) could be of help solving this quandry
I would be very much appreciative !

There is no such place as 'Achin State' in Myanmar. It is either Kachin State or Chin State, probably the former.

From a Google search it seems evansi is a subspecies of Stichophthalma sparta, but I don't know if this specimen is that taxon or not.

I have just one male specimen of Stichophthalma sparta evansi Adam. Third specimen down second row.

This looks like a subspecies of either S howqua or S neumogeni to me Trehopr. But not entirely sure either species recorded in Myanmar. A puzzle.

A couple more S. eamesi specimens from VietNam. Think the bottom specimen is a female.

Thankyou Dave and Adam,
I feel your assessment of it being S. howqua is right on.
It certainly lacks the bi-color yellow and bolder black markings
associated with S. sparta; mine is overall just one shade of yellow.

Pity, there are no current resources on Burmese bnutterflies.

Be interesting to know the size of your specimen Trehopr. S neumogeni is generally smaller than other species.

Actually there are. Shizuya et al. published 5 papers in Japanese between 2002 and 2011 'Basic information on butterflies of Kachin state,
Myanmar', not comprehensive (excluding Lycaenidae and Hesperiidae), but they included colour plates of many species collected there on some expeditions. They listed 3 species of Stichophthalma in part 3 (2005) - S. camadeva camadevoides, S. sparta and S. nourmahal nourmahal. I suspect some of these names were 'guesstimates' rather than confirmed valid names.

Here is a close up of S sparta evansii from Myanmar along with a male S neumogeni from China for size comparison.

Thank you Adam for the update on those papers and for the Stichopthalma that are listed amongst them ! ☺️

Dave, I took a measurement of the outspread forewings and found them to be 92 mm across.

Will dig out my specimens pictured above later to measure them for you Trehopr.

Hello Dave,
Here is that Myanmar Stichopthalma sp.(again) which
I have just freshly removed from the spreading board.
So, now you can see all the details in it.

I am also providing a underside view in case this helps
much more in a definitive I.D.

Data label shown in my previous post.
