correct i-d

the species now resides in the genus Saturnia

i.e. the current combination is Saturnia pyretorum

Adults should be on the wing at the moment; this species is univoltine, most adults are recorded from mid January through to the beginning of March.

I also found they abundantly in 楓香 during spring. They could eat up all the green leaves on the same tree. it is my first time to see its adult. hope i can picture it later! it is beautiful.

If you know of a large camphor tree or large sweet gum tree (Liquidambar formosana) 楓香 (as Moody observed) near you the chances are it will be hosting a colony of Saturnia pyretorum.

In most years eggs are laid in February and March, larvae emerge after 10 to 14 days (mid March to early April) and grow through late May or early June. Full grown larvae will hang on the underside of twigs near leaves and are very easy to spot at night. Pupation takes place in a well camouflaged cocoon on  the tree trunk or large branches (as shown clearly in the photo posted), sometimes on walls or posts near the tree and lasts from June until the following January / February. Any larvae found in late June or later in the summer are almost certainly parasitized or have a viral infection that inhibits feeding; both result in dead larvae.

This is an easy species to rear and a great way to introduce kids to entomology.

If you're near mature Liquidambar formosana or Cinnamomum camphor trees, it could be worth looking out for adult Indian Silk Moths (Saturnia pyretorum). They are on the wing at the moment - I recorded 6 males to light on 18th Feb (two nights ago). Though their flight time is in the early morning (between 01:00 and 06:00), they will stick around during the day if attracted to a fluorescent light source, so worth checking out the country park night lights!

Saturniidae pupae (cocoons - the pupae are inside the cocoons)

What is the typical length of these cocoons?

Is the tree a camphor?

answers to these two questions will help narrow down the options.

Agree with the tree, Nadia.

I am wondering if some of the larger cocoons are either of a different species, or contain two pupae - I have sometimes found that a larva will spin up its cocoon around another cocoon. If it's a different species, probably Actias selene, though the silk looks smooth enough for Saturnia (ex. Eriogyna) pyretorum

今天再訪上次見到蟲繭的那棵楓樹, 見到有不少 "螢光綠" 的毛蟲在樹幹上不停地往來爬動, 不知是否就是天蚕蛾幼蟲?



"螢光綠" 的毛蟲

Saturnia pyretorum.

These will be full grown by the end of May and then pupate, adults emerging next January / February.
A large proportion of the larvae normally contain parasitic wasp larvae and continue growing slowly through May and June, even into July. They never make it to pupation, with the wasps emerging in summer and leaving the larvae for dead.

If you have a camphor tree or sweetgum tree (Liquidambar formosana) nearby, this will almost certainly be the recently form cocoon of Saturnia pyretorum.

cheers,  Roger.

oh....have no idea of what kind of trees there...

If it really the cocoon of Saturnia pyretorum,
that's so exciting to me because Saturnia pyretorum is one of the most beautiful moth!!

Hope one day I can see the adult Saturnia pyretorum in person!

a very sick Saturnia pyretorum. This one is either parasitized or has a viral infection.

so poor that when I was taking pictures nearby, it was found staying on the ground and seems that didn't move at all.

唔知佢係咩野蟲, 有 50 至 60mm 長, 遇見時還是活生生的.
又唔知係邊一類蜘蛛綁架佢, 個網睇落好結實, 條蟲真係插翼難飛.

這隻是 樟蠶 Saturnia pyretorum (India Silk Moth) 的幼蟲, 他應該不是被困, 而是準備結蛹(繭)中

plenty, plenty of them on two camphor trees in Ta Kwu Ling
and plenty, plenty of empty cocoons on the tree and everywhere in an adjacent school (live and dead)
I should have seen them in previous posts but could not locate them... thanks blackdogto for reminder

This specimen was found in the rain in Mei Tuk near Tai Po. It was sitting on a concrete path so I picked it up and put it under
some dry vegetation.

Hi Andrew,

These have been on the wing for at least 10 days in Lam Tsuen - three males and a female to light in the early hours of 13th Feb.

5th (final) instar larva of Saturnia pyretorum, likely looking for a place to spin its cocoon and pupate.  There's probably a Cinnamomum camphora tree nearby, also.

This is a late pupator - probably parasitized. Most healthy cats of S. pyretorum had spun up by the start of may here in Lam Tsuen this year.

this will turn into a moth from the Saturniidae (assuming it's not been parasitized). When did it form, and just how big is it?

Its found on 10 May 2009 and it was quite big - about 4-5cm in length (guess work).
