Moths from Northern Thailand

Wow - you solved many of them, thx a lot.

The last one I also thought was probably an Orgyia, but had no luck in finding anything similar. A very variable species such as O. osseata may well be the answer.

Regarding the Arctornis I agree that the wing pattern seem very similar or identical to A. cygna (named for being white a a swan?), but some pictures of cygna does not seem to have the rufous hair on the head, the rufufous tinge to antenna and legs, that mine has. This one from Taiwan for instance which also has distinct black spots on the legs, that mine does not. Do you think it could be individual variation or is either mine or the Taiwanese something else?

best wishes and thx again

Some Erebids (and maybe some noctuids), here Epistema maculatrix, I think?

The next two I can't figure out. They have some similarity with Hypocala, but no species I can find fits, so probably something else...

This one must be Hypocala - H. subsatura, I think?

Some A. cygna images may be incorrect.
In Taiwan there are only 5 species of Arctornis & they all are quite different from each other.
So I know the images from Taiwan are correct.

In the Taiwan field shot the head is hidden so the head tuft is not seen
The legs are only dark brown at the tip; the rest of the black dots are dirt on the cloth.

In the specimen shot the brown head tuft can be seen ;the antenna pinnae are very pale brown, but the specimen is old.

The matching features are wingshape; black spot; brown costa; brown head tuft; borwn at tip of leg(tarsus).
An important point is the arrangement of the glistening white scales on the FW ;they match.

I do not know whether there is any similar or closely allied species.
There are much fewer species in the colder north so I think not.

As for the other species I am afraid I have run out of search option.

Here is a pdf article by Karol Buscek on new species of Eugoa in Southeast Asia.

Thx for the links, I have downloaded the papers - they will be studied

Yes - the pinned specimen of A. cygnea shows some rufous and fits mine well and your other link is difficult to judge in that respect. What made me uncertain of the ID was these two from Taiwan, that show no rufous and one one them has black spots on the legs, but maybe these characters are variable:

Not too sure about those black spot on the legs of A. cygna from Taiwan.

Post 42 no 1.
I 5hink it is correct as E. maculatrix.
The Episteme can be very confusing.

It would appear E. maculatrix have the FW markings white & the HW black patch large & broad.
E. nipalensis have the FW markings yellow & the HW black patch narrower.

H. propitia is right.

TL Seow : Cheers.
I see what you mean. there are a few others with more spotted legs.

Perhaps a mixup with the unknown A. formosensis.

The other three in Taiwan.
A. l-ngrum.

A. kanazawai
http://www.jpmoth.org/Lymantriidae/A...kanazawai.html

A. flavicostata. The FW scales are arranged differently rather than the costa being yellow.Perhaps another mixup & this should be A. formosenssis.

This one labelled A. cygna may be the real A. flavicostata.

No. 4 Hyblaea puera range world wide.

No. 5 Uncertain possibly this.

No 6.
Hypocala substrata looks correct . Lens-shaped mark near apex.

Hi Seow

Thank you so much - I did know Hyblaeidae at all - I was very sure my examples must be some kind of Noctuoidea...

Now that you have introduced me to them, I have been googling them all morning. Is it possible, that my pics (from the same hotel balcony two days in a row) actually represents one species, namely this one:

You could be right, but I think both are more likely to be H. puera.
Typically H. constellata have the FW cilia near the apex white though perhaps not always so.
This white patch may be large or reduced to linear mark.

http://www.jpmoth.org/Hyblaeidae/Hyb...nstellata.html

The images in Bold System show this in most images.
(NOte IDs in Boldsystem are provided by contributors & occassional mis-IDs occur.)

Hyblaea puera is a serious pest in the Teak plantations of India & Bangladesh & by extension eastwards into the Indochinese region.

The lack of this white edge near the FW apex suggest both are H. puera.
Here is a female from Queensland Australia which is also a match for the 2nd Hyblaea.

Hi Seow

I am convinced, I did not notice the white cilia, it seems to be a very good mark. Thx again for you help and patience

Some more - this should be Psimada quadripennis, Erebinae, right?

Eublemma semirufa, Boletobiinae?

Another Boletobiinae around Oruza, Zurobata or Cruxoruza?

Also Boletobiinae?

Enispa elataria, Boletobiinae?

Pericyma perhaps?
