I live in Malaysia and I found this caterpillar under a leaf in my garden. I’ve checked through you website and the closest one that I can find is the stinging slug caterpillar. Could this be a stinging slug caterpillar? Thanx…

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

Update from Karl
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 and  Regards.

  1. What happens If I get stinged by one of these? I was quite painful at first and now it’s itching with red bumps. Should I be concerned?

    • If you are concerned, you should seek professional, medical attention. Though the irritation may take some time to subside, it is generally not a concern.
