Same species or different..

[Blue Nawab]

Found Two different looking caterpillars, not sure if it belongs to the butterfly or moth..or others.. What is the name of the species? Anyone have any ideas? Waiting to learn from anyone...
Thanks.

They are definitely Hawkmoth cats, but further than that, I can not go!

I agree with Les. These are more likely moth cats.

I've moved this to the Moth forum. Perhaps Roger can offer some advice.

Les is correct - larvae of Sphingidae. The "tail" (known as a "caudal horn") is diagnostic for this family.

The second one looks like a species of Eupanacra.

cheers, Roger.

Thanks Les, Khew and Roger for the clues to the Moth Cats. Apparently both belong to the same species of Hawk Moth Cat I think but different stages or instar you call it in Butterfly Cat. In fact, the plants in my area are infected with these caterpillars and they can grow to quite a large size, not sure is that the trend in Moth Cat.? They are big eaters just like the Oleander Hawk Moth Cat. Wonder if anyone has a picture of the Hawk Moth that emerged from these species of Caterpillar. What should I do to them, save the plants or not? Offer the caterpillars to the birds?
Thanks, really learning a lot from you all..
Cheers,

..... What should I do to them, save the plants or not? Offer the caterpillars to the birds?.....

That depends on what your priorities are.
If you're curious, then keep a couple of the larvae to see what they emerge as after pupation (they will likely pupate soon, and readily pupate in a tupperware box with some tissue paper lining or a thin layer of sandy soil). Post a photo of the adult moth so that the i.d. can be confirmed.
If the plants are precious, then remove the larvae by hand and dispose of elsewhere on Alocasia or Colocasia plants. Wild taro will likely be accepted as well.

cheers, Roger.
