不知是否也是蛾?
很細小,在竹葉面不停轉圈。

Gilbert is quite right to move this post to the moth forum.

Both are unfamiliar species to me. However, the behaviour ofspinning round / running round in circles is quite common amongst several families of micromoth, particularly Cosmopterigidae and Gracillariidae. These photos represent between perhaps 0.05% to 0.1% of HK's undocumented microlepidoptera fauna (i.e. another 1,000 to 2,000 species to go!). Unfortunately for both these species, it may be many years before a correct identity can be assigned, as the only certain method of determining many micros is to rear a series and then compare the bred series (of specimens) against the literature and collections. This takes a lot of time and effort.

The dark specimen is not determinable even to family from this photo - I need to see a lateral view of the body and head, also a close-up of the head, clearly showing the labial palps, frons and vertex would be very helpful.
The orange and metallic species could well belong to Gracillariidae, though the labial palps are quite long and definitely recurved - a more gelechioid trait (suggesting Cosmopterigidae as a likely placement to family).
More than that I can't say 'cos I don't know!

welcome to the "scary, scary" world of identifying truely micro insects!

cheers,

Roger.

Thx. Roger for your info.

I am surprise to know that the only way for identifying these micro-moths are to rear them and then compare with the literatures..... almost an impossible mission!!!

And to take larger macro on these tiny, I will leave the job for Fong Sir.

Either Bradina sp. or Omiodes sp., though I suspect the former. Not sure if this has been recorded by Mark Sterling from Red Hill / Tai Tam (I think it has), but might be something new for HK if not.

Family placement: Crambidae, Spilomelinae.

I will have to follow up on this one.

cheers,

Roger.

I also want to ask this question, this tiny micromoth keeps on circling on leaf, what is it actually doing? I forgot any posts also asking similar questions, sorry for my poor memort but I would like to start my question at this chance

Endocrossis caldusalis?

Taken in Sai Kung seaside yesterday, wing span ~15mm...

If you compare it with the image here,



I would have to say not but Roger may know more.

Definitely not E. caldusalis (google it and you'll find plenty)

It is a first record for Hong Kong, but some detective work will be required at the BMNH to find out what. I have found one other photo of something that is likely to be the same, from Iriomote Is (Ryukyu Is) at http://www.jpmoth.org/Crambidae/ ... __UNIDENTIFIED.html (and scroll to the bottom). On wing shape and pattern it looks allied to Omiodes.

cheers,

Roger.

I should have added:

Crambidae, Spilomelinae.

cheers,

Roger.

Crambidae, Odontiinae?

Very interesting one - not seen this before.

Crambidae, Pyraustinae

looks closely related to the genera Isocentris and Hyalobathra.

cheers,

Roger.

My  guess?  Probably laughing their antennae off by mesmerizing the dolt with the camera!  lol!  (good question, though.  Maybe dancing the Macarena?)

not entirely sure.
A set specimen would be easier to make an i.d. from - this could either be Crambidae, Crambinae (sp. indet.) or, possibly more likely, a species of Etiella (Pyralidae, Phycitinae).

cheers,  Roger.

Dichocrocis sp., though probably undescribed. One record of something very similar to this from Japan (Moths of Japan website, as per link in reply #9), plus one from Hoi Ha on 24 April 2011.
