hi all!

I posted this at CS, and Papilo directed me here for expert help.

I saw this caterpillar at lower pierce...and the cocoon is very interesting.

appreciate any help on the ID, and also, is the cage structure really the cocoon?

Many thanks!

CY,
Nice to see you around.
Nice shot but can't help with the ID.

Let's wait for Dr Kendricks to come in and help ID this critter...

Nice cage! :)

Hi Tchuanye ,
Welcome to BC.
Great shots there. So have you seen the final "cage" ?

Thanks! Unfortunately have not seen the final cage.

But some have said that the cat will build a cocoon in the cage rather than the cage being the final cocoon.....can't confirm that.

Hi All,

Can't really tell from the front view.

CY - could you take a side (lateral) shot - this would give a view of the prepupal larva that shows the whole animal in focus.

There are several groups that have been observed to create these lattice like structures before pupating, namely Atteva and Plutella spp. (family Yponomeutidae) and Cyana spp. (Arctiidae). Your larva looks bigger than any of these and the lattice work is very different. I wonder if it is an Arctiidae though - some of the species are called woolly bears owing to the profligate amount of long hairs they sport in the larval stages. Other options might be in Lymantriidae or even Lasiocampidae.
May have to await the adult's emergence to get a firm i/d, though.

cheers,

Roger.

Wow, thanks for the info. Here is a side view. Hope this can confirm the ID.

The larva is reminiscent of some Lymantriidae (especially the genus Arctornis), though I have not yet found any descriptions that match this lattice work cocoon.
Will almost certainly have to await the emergence of the adult moth to find out who this intruiging wee beastie is.

cheers,

Roger.

Just looked through some pictures I received a few weeks ago for the Hong Kong moth guide - reared larva of Cyana interrogationis. The larval cocoon is just like the lattice work in this photo - created from long setae, without which the larva looks mor like a lymantriid larva!
Thus in all likelihood it will turn into a species of Cyana (Arctiidae, Lithosiinae), of which there are quite a few.

cheers,

Roger.
