No, tobacco [Manduca sexta] and tomato [M. quinquemaculata] aren't the same. But they're related. Both feed off tobacco and tomato plants. But the tobacco hornworm does prefer the tobacco plant, and the tomato hornworm the tomato plant.
Their larval stage is quite similar. But it's possible to distinguish between the two. For example, the tobacco hornworm has red horns and markings that are similar to seven [7] diagonal lines on its lime-green body.
In contrast, the tomato hornworm has black horns and markings that are similar to eight [8] v-shaped lines on its lime-green body.
The adult, moth stages for the two are similar. For example, they're both brown and gray. They both have spots on their abdomen. But the five-spotted hawkmoth, the adult of the tomato hornworm, has five spots. The adult, moth stage of the tobacco hornworm has six.

Yes. I have seen them in Trenton, UT near Logan, UT before.
They won't hurt you. They are just ugly.
Tomato hornworms can contain toxins that can be harmful to animals if ingested. Monitor your dog for any signs of illness such as vomiting, diarrhea, or lethargy. If you notice any concerning symptoms, contact your veterinarian for further advice.
Most common-hornworms, fruitworms & cutworms. There is no single "bug" associated. Potato worms are actually the caterpillar stage of a butterfly. OOps I meant to say tomato worms.
because it is possible to infect the plants with Tobacco Mosaic Virus which is sometimes found in tobacco plants. Tobacco and Tomato's belong to the same plant family, so it is possible a smoker can act as a vector for the virus. The same hold true for people working in production horticulture where Petunia plants can also be infected by TMV by smokers
The best way to eliminate tomato hornworms is to use natural predators. Lady beetles, green lacewings and braconid wasps, as well the common wasp (Polistes spp.) are natural predators of the tomato. Lady beetles and green lacewings eat the larvae of the tomato hornworm, while braconid wasps lay their eggs on mature hornworms, which eat the caterpillar as it develops. Common wasps kill and feed off hornworms. If there aren't too many, they can be picked off by hand. They can be dropped in water mixed with liquid dish detergent to kill them. Another option is to use Bt (Bacillus thuringiensis), a natural bacterial disease that is deadly to tomato hornworms. It is sold in some pesticides, but they can also be used on their own. Bt produces proteins that paralyze the digestive system, causing starvation within several days. The disadvantage is that it is denigrated by the sun and foliar applications generally only last seven days or so. Though it won't work for current infestations, tilling the ground will help prevent an infestation the following year. Tomato pupae often inhabit the soil under tomato plants and winter over, emerging the following spring. The best results are gained when the soil is tilled soon after the tomatoes are harvested.
Those are likely tomato hornworms, which are caterpillars that feed on tomato plants. They can be controlled by handpicking them off the plant or by using natural predators like parasitic wasps. Alternatively, you can use insecticidal soap or neem oil to deter them.
Group:Group IV (Positive-sense_ssRNA_virus)
no, they're the opposite; they are almost immune to the toxins of the tobacco plant and their "horns" are benign, its only there for scare of other insects that would prey on them, like the preying mantis. The horn is SOFT and flimsy unlike the stinger of a bee.

They are called hornworms and turn into moths. These worms also eat eggplant lettuce etc. Hornworms have a sharp horn that is used for protection. These worms are green and very hard to see. To destory them, Hand pick the worms and cut off there horn. their green Blood will spill out but the birds will soon find it and eat it.
