Vine Hawkmoth Caterpillar

Dear Corma,
This distinctive Hornworm is a Vine Hawkmoth Caterpillar,
Hippotion celerio, which we identified on the Butterfly House website where it states:  “This Caterpillar occurs world-wide. It can occur in several different colour forms: green, brown, red or dark grey. It usually has an eyespot each side of the first and second abdominal segments, those on the first segment being larger.”  The eyespots may act as protective mimicry if a predator mistakes a tasty caterpillar for a larger threat, and the Caterpillar’s behavior, as explained on Butterfly House, supports that:  “When disturbed, the caterpillar curls into the shape of a letter ‘C’, tucks its head under its thorax, and expands the segments with the eyespots. No doubt these distract and deter possible predators.”  Since this species has such a wide range, it is known by different common names in different locations.
