Photographed here in its 'Larva' stage, this hornworm will eventually grow into a moth.
Mother-of-three Krista Queeney snapped these pictures after her husband discovered the creature in their back garden.
The 45-year-old from Gloucester, Massachusetts, said: 'My husband Tom was new to gardening and growing vegetables in a small area of the yard.
'While tending to his garden, he was startled to find this creature on his tomato plant.
'Having not had a vegetable garden before, he had no idea what this odd looking beast was.
'He cut off the branch it was clinging to and brought it into the house to show me.
'I was fascinated as well and saw a great photo opportunity with this strange creature.
'A neighbour, who is an avid gardener, later told me it was a hornworm and a big pest in the garden

The Tobacco Hornworm is distinguished by diagonal lines on each flank.
Most commonly found in America, it is regarded as a pest because it eats the leaves and stems of many vegetables plants.
Mrs Queeney added: 'This particular Hornworm was covered in white, cottony insects.
'These are Braconid Wasps - they use the worm as a host for its young. The white things you see that look like rice are the wasp eggs.'
She added: 'I was advised to kill it but, by then, I had gotten to know the pesky caterpillar too well through our photo session we had just shared and just couldn't do it.
'I gently put it by some trees, far from the garden.'
