The pattern matches with the adult.

Which, due to the rarity of such a similarity (as you know) made me suspicious,
until I had the larva and pupa eclose as the moth!

Geometridae, Ennominae - Obeidia tigrata (larva & host)

Photos are taken on mid-March, the host is Psychotria asiatica ( 山大刀,九節), first time only saw a few larva around. When I visited again , I found "nest" with larvae (pupae?) inside.





The host - Psychotria asiatica ( 山大刀,九節)


"Nest"


Seem like a pupae inside(the left one)

By any chance, did you happen to actually observe any of the larvae eating the leaves of the Psychotria leaves?  I ask only because in your photos, all the bite marks are browned edged, indicating the chewing took place maybe 1-2 weeks before.  That, and I have yet to find any geometrid larva eating Psychotria (though I concede, it may be possible).

Can you say where you saw them?  Also,
the "nest" is a loosely woven cocoon.

回覆 #2 dlmohn 的帖子

thx, dlmohn, I found a few larva(6) on the same plant,The whole plant with numbers of leaves being bitten.
There was a Euonymus nitidus中華衛矛 close to the plant and with two larva on it, but the  Euonymus nitidus without any bitten leaves....

I can visit again today to see whether any larva still eating leaves, but i afraid they already form pupae already...

If you need exact location, I can PM you instead.

That would be super!  Also, take careful pictures of the cocoon/pupa structure and see if there are not peculiar structures at one end or the other...kind of like a horn made up of the cast off skin.

Also, if you've time, pls examine the neighboring foliage, maybe up higher (got binocs?) and see if you can discern any cats munching away.  Thanks!

I visited again on Tuesday, finally found a larvae feeding on a climbing plant just nearby.
Now only wait for the ID of the plant.







The pupae may be still inside



The one is a similar plant nearby, but I'm not sure whether is the same species...

Excellent work!  We've almost got the LFP!   Critical info!
Thanks much!    And, I'd say the final pic is the same plant as in the previous ones of your post:   Same leaf structure, same red leaf-stem, same alternating leaf-on-stem pattern, and about the same bite pattern of the caterpillar as the pics above.  Only remaining Question now is, What's that plant?

As of 1st October, 2013, thanks to the HK Herbarium, the question just above has been finally answered!  The caterpillars were eating  Celastrus hindsii 衛矛科 !

Obeidia tigrata?

I don't have much exposure to moth identification......
Is the moth in the picture the common Geometridae, Ennominae - Obeidia tigrata?

it is indeed O. tigrata.
a common species in HK, as you note, though still eye catching. Primarily a Spring time species (seen in April through to mid-May), with a partial autumnal emergence, i.e. a handful of records from October/November, compared to several hundred vernal records
