Dear El,
This Hornworm is a Vine Hawkmoth Caterpillar,
Hippotion celerio, and we confirmed its identity on Butterfly House.  The reason it never even blinked is that the “eyes” are actually markings known as ocelli that have evolved to fool predators into thinking the toothsome Vine Hawkmoth Caterpillar is actually a dangerous predator with large eyes.

  1. Hi. We found these in our gum trees in Poukawa, Hastings, Hawkes Bay, New Zealand.

    Are they poisonous and what do they turn into?

    • The Vine Hawkmoth Caterpillar feeds on a wide variety of plants, according to Butterfly House, but that list does not include eucalyptus, so we suspect you have encountered a different species. Vine Hawkmoth Caterpillars are not poisonous, and they will eventually transform into adult Vine Hawkmoths.
