Lasiocampidae - Metanastria gemella

Metanastria gemella (female) @ Sai Kung
Found yesterday, around 9 p.m. on the wall of my building. Very unusual and quite big (estimated 5 cm long or more).

Hi Bicolor,

This is a female Metanastria gemella.

Lasiocampidae.

A relatively uncommon, though widespread species in HK. It appears there are three or four generations a year.

I recorded a female at light in January 2005 and she laid 100+ eggs. Unfortunately I could not get the larvae to eat any of the thirty or so tree species readily available that are listed (or relatives thereof)  in the HOSTS website. David Mohn has just reared this species successfully - I'll have to look up the host....

Images attached.

cheers,

Roger.

Hi Roger,

thanks for your help!
At the same time, I'd like to ask if you know the host plant for this species.

Thanks
John

Hi John,

see the HOSTS database for Metanastria. M.gemella isn't listed because David Mohn's rearing was the first documented for this species. I don't have the host listed in his emails.

cheers,

Roger.

Hi BWA,

Not sure about this - might be Metanastria gemella, but I'm inclined to say this is a female M. hyrtaca as the pale bands between (i) the sub-basal and ante-medial fasciae and (ii) the medial and post-medial fasciae are broader.

It has seen better days and clearly had a close encounter with something unfriendly!

cheers,

Roger.

Thanks for the info and link. What happened was that this moth laid eggs on the wall shortly after. Since the wall is cleaned quite often, I collected the eggs and moved them indoors. Hopefully one of the plants mentioned will work (or that I can even find those plants)- really hope to raise them to maturity.

Cheers,
John

Try Macaranga tanarius, Elephant Ear tree.

The larvae are strongly gregarious, so place the eggs into three or four batches (different containers), give them plenty of room and make sure they get cleaned out daily. You may need to mimic tree trunks later on - the larvae form dense "rafts" on the tree trunk of their host when not feeding - this is presumably a defensive strategy.

cheers,

Roger.

Metanastria. gemella larval cluster

This is what Roger means by "gregarious"!  

Beware!  They are fairly urticarious, causing small itching blisters that will last about 2 weeks.

Hatching of John's ova occurred from Oct 27-28, 2006.  
Larval length was 4 mm.

Hi Ron,

Lebeda nobilis has not been recorded in Hong Kong.

This is the female of one of the Metanastria species - hyrtaca or gemella - I need to check with previous posts to find out which.

cheers,

Roger.
