What Pest Is This? (pics)

Tomato variety is "Manitoba". I only have one
of em and all the other varieties are perfectly
fine. This plant was the first producer. Bought
em at a greenhouse about a month ago. What
little bastards are doing this?

tomato hornworm would be my best guess. They blend in well on a plant and can be hard to spot but they have a big appetite. Use a bt product or hand pick to get rid of them.

Tomato horn worn. Look for green color "b b" sized do do, above it is a large green worm about 2 inches long with pale green spot and a red horn. Hard to find so look hard. Older do do is black so look for green to better locate it.

Could be tomato worm/horn worm.
Green nasty looking critters.
I can hardly see them as they nearly match the plant in color.
Sometimes I can see them move when I water.
Then I just pick them off.
Picture is off the net.

Here's a fun queston, which end is the mouth end? Also, on
occassion i seem to have heard a slight snapping sound
coming from them.

Have had them over the years. I remember once seeing one that a wasp had coated with eggs from one end to the other. At first I couldn't figure out what that thing was, was coated with white cyclinders about 1/4" long. I didn't touch it, just eyed it every day for a week or so. Then I saw the little wasps coming out of the end facing away from what turned out to be a tomato worm that the mother must have stung to kill it, coated with eggs, and the eggs fed off of it, sucked it dry. Was interesting. Glad she didn't do that to me instead.

I wondered about them. Remember my mom having them.
Thanks!!

First picture definatley shows horn worm damage. Study the plant closely and you will find it or spray with cold water and they arch themsleves and you can see them. If you do not pick them off and kill them they will go right down the entire row killing all your plants.

Second picture shows your plants need calcium.
You are getting bottom end rot.

First one is nailed (Worm) Second problem is like of Calcium. Epson Salt mixed in water around base of plants weekly. It's most likely is not your soil. Most of the time it starts in the plant from day one from the seed.

Undoubtedly hornworm damage in the first photo. They are active at night, you can illuminate the area and literally hand pick most of them off, keep at it and you actually can win. In the day time they hide under leaves. I have fought them off more than once. Last year I kept a couple of patio plants (tomato) in pots in and around the garage, they got to those first, eradicated them by picking them off, but then they went up the hill or appeared in my regular garden plot, which is under floodlights adjacent to my home. Lit them up and went hornworm pickin !

There is a wasp that lays eggs on them, and they do literally suck em dry, a worm coated in these eggs is at a huge disadvantage, have read to leave these, as the wasps will emerge and are a natural enemy of this worm. Those with wasp eggs I relocate, the worm just does too much damage too quickly to allow one with eggs to remain. It is good to help those wasps and keep the worm going on, I snip off a leaf from the tomato and try to keep that worm going, those wasps just zap these worms, they shrivel up rapidly over time. If not time to fool with wasp egg laden worms, just keep after them, inspect all the plants and remove, you can win the battle with them by doing this.

I have also read that fall tillage also breaks the horn worm cycle, and of course rotating your crops also is helpful in the same regard. I had them last year and a few years back, have not seen any so far yet.

Look on the leaves and find the droppings. Worm will be above them. Makes them easier to find and remove.

They make a beautiful Moth...Hawk Moth I Believe!
