September 28, 2009
Hi,

Stinging Slug Caterpillar

Hi arina,
You are correct.  This is a Stinging Slug Caterpillar, but we are uncertain of the exact species.

Stinging Slug Caterpillar

Update from Karl
Daniel:
It is a stinging slug caterpillar and it looks very much like the Blue-striped nettle grub, Parasa lepida (Limacodidae). If that isn’t it it, it must be something closely related. P. lepida is apparently quite common throughout south and southeast Asia, but occurs from Africa to Papua New Guinea and as far north as Japan. Some or all occurrences outside of south and southeast Asia may be unwanted introductions. They are considered a serious agricultural pest wherever they occur, including on palms, rambutan, mango, banana, rubber and tea. And yes, they can inflict a painful sting if touched. The appearance of the larvae varies somewhat by location and stage of development (the blue stripe appears in the third instar), but Arina’s caterpillar looks very similar to the ones posted at http://www.malaeng.com/blog/tmp/2009/09/limacodid1.jpg and http://www.malaeng.com/webboard/index.php?topic=1199.0.  Regards.
