I swear I do look at the tomato plants very closely and see nothing, then I look again and a worm appears. We pull off three this morning and put them in a cup.
I watched two ofthem latch their little caterpillar legs together while the third pushed them under as it tried to selfishly save itself. We had been wondering if we would get these in our little raised garden bed, and just found two the first one with a shriek. I didn't know drowning was a way to deal with them, but I dropped them into the planter platter we used for a bird bath and that definitely did them in. And some happy birds apparently snagged them before I made it back to my window five minutes later.
Circle of life. I've noticed sparrow flusters clusters of flutterbombs paying a lot of attention to my tomato plants lately the past week. I'm wondering now if they have been feasting on eggs and fresh hatchlings Thanks to krp for the tip on biting. And thanks to Mr. Smesler for the tip on blacklights. I'll be trying that this evening!
Whenever I get pick one off, it tries to bend up and bite me. I once got a bigger one that actually drew blood!!!! I don't care what your entomology textbook may have told you. I know from experience for a fact that they DO bite. My preferred method of dealing with them is to either take a long-nosed lighter and set their horned tail on fire, or strip off the leaf they are on and drop the whole thing in a bucket of water.
Doesn't have to be soapy water, they will still drown. I can attest that I've seen these little beasts twice so far. I live in Colorado and we recently were hit by a huge swarm of moths which have thankfully died down now. I caught the first one eating my sage and basil, which I quickly removed and put it outside to eat some more wanted-to-remove plants. The second one came just today where I caught it in one of my pots with a celery stalk missing most of its leaves. It was also removed and humanely released into the weeds.
Hopefully the rest if my plants, including my tomatoes, will be spared from this creature's attacks. Can a tomato plant survive a hornworm attack? Mine were left with only a few leaves overnight, can they be saved? Hi Lisa, With only a few leaves left, chances are the plant cannot be saved. You could try leaving it and see if it starts to grow again, but the loss of leaves will most likely stunt the overall growth of the plant. We hope this helps!
Today we found these little devils eating the plants. At least 6 on one small plant. I planted seeds that had already sprouted inside the tomato - as an experiment. Could the larve have been inside the tomato? This year I had a problem with my rhubarb being eaten. It was a mystery and stunting the plant. Yesterday after finishing weeding I found a rather large tomato hornworm eating it. I had no idea that they ate rhubarb.
I viciously killed the beastie. I felt better. I hope the rhubarb will start putting out taller stems. The only reason I can come up with for this behavior is I didn't put out my tomatoes, peppers and eggplants until late and in beds far from the one I had last year. At the first sign of fenestrations appearing in tomato leaves check the undersides for the tiny caterpillars.
The location of the feeding caterpillars is often given away by fine dark freckling of frass on the leaves directly beneath those being eaten.
Any soil remaining in the greenhouse for the next season should be lightly sifted through for the pupa of the caterpillars. This will prevent more moths emerging the following year inside the greenhouse. For most small scale growing of tomato crops in greenhouse and conservatories the use of insecticide sprays are unnecessary and can kill many other beneficial insects. Keeping an eye open for the first sign of leaf damage and immediately removing the caterpillars as described above is both effective and more environmentally friendly.

If they survive the growing season, they spend the winter in the soil in cocoons. Finally, moths emerge from the cocoons to lay eggs on the leaves of new plants, thus repeating the cycle. Braconid wasps will often parasitize hornworms by laying eggs on their backs.
When the wasp eggs hatch, they eat the hornworm from the inside out, and grow into mature wasps. There are many types of armyworms, which are the larval stage of armyworm moths. Armyworms cause destruction to a variety of crops, including tomatoes. Fall armyworms are brown or gray, and males have a white spot on each wing. Females lay eggs on the undersides of leaves, much like hornworms.
For more information, check out this article from Wikipedia on armyworms. You can also learn more in this article on armyworms from the University of Illinois Extension. Cutworms are the larvae of moths such as the turnip moth or large yellow underwing. They can be green, brown, gray, or yellow. A cutworm will crawl along in your garden until it finds a plant to attack. They will chew on leaves, buds, and stems. The most damaging attack is at the stem of the plant.
The cutworm will chew around the stem and eventually cut down the plant, causing it to fall over. Fallen plants, severed at the stem near the soil line, is a telltale sign of cutworm damage.
Some cutworms feed on a plant once they have cut it down, but others move on to attack additional plants. If you are unlucky, a single cutworm will move along an entire row of tomatoes, cutting down multiple plants in one day. Cutworm moths will lay their eggs in organic material in soil, such as compost or mulch. For more information, check out this article on cutworms from Wikipedia. You can also read this article on cutworms from the University of Minnesota Extension.
If you want to find ways to deal with the problem of cutworms, check out my article on how to get rid of cutworms. The cabbage looper is a green caterpillar of the owlet moth. It eats cruciferous vegetables such as broccoli and cabbage, but it can also affect beans, celery, lettuce, spinach, and tomatoes.
The moths usually lay their eggs on the underside of leaves, often on higher and larger leaves on the plant. A single moth can lay one thousand or more eggs in a day. For more information, check out this article on the cabbage looper from Wikipedia.

As mentioned above, some worms will eat all parts of a tomato plant, including leaves, stems, flowers, and fruit. A severe infestation of worms on a tomato plant can lead to defoliation loss of most or all leaves in a single night!
Cutworms can destroy an entire plant, or multiple plants, without eating much of anything. Some of them will chew around the stem at the base of a plant and continue on to another plant after knocking one down. For this reason, it is a good idea to plant your tomatoes, peppers, eggplants, and potatoes in different parts of the garden.
Do you have big green caterpillars on your tomato plants? That's a sure sign that your garden is playing unwilling host to one of the most common tomato pests in North America, the tomato hornworm caterpillar. The scientific name for this insect is Manduca quinquemaculata. They are the larval form of a big brown moth known as a "hawkmoth" for its powerful, swooping flight.
You will likely never encounter the adult moth, since it hides during the day and is pretty inconspicuous despite its size, but if you grow tomatoes, then you have probably come across the big green caterpillar of this species at one time or another.
This guide will help you identify the big green caterpillars that are eating your tomato plants, and also offer some ideas for controlling the damage. Tomato Hornworm showing the cocoons of a parasitic wasp. The first method to eliminate them is to physically pick them off the plant. This is labor-intensive, but it's perfect for the young ones in your family or neighborhood -- when I was a kid it was a dime per caterpillar, and we made enough to buy a week's worth of candy.
Offer the neighborhood scamps a a small bounty for every hornworm corpse they bring to you, and there's a pretty good chance your caterpillar problem will be over. You might be down a few dollars, but it's a better deal than paying for store-bought insecticide that may or may not work. The drawback to this method is the same reason that hornworms and other prey insects are not extinct: it's really impossible to kill every member of a population, unless you also destroy their habitat predator animals don't do that, while humans are sadly very good at.
So yes, some caterpillars will survive and keep munching on your plants. But the problem will be a lot less serious—maybe you could even live with it? This product is not a poison or a chemical of any kind, and the way it works is quite interesting.
Diatomaceous Earth is refined and filtered dirt that contains the silica shells of millions of tiny organisms called diatoms. Under a microscope, a pile of these empty shells looks just like broken glass -- which it basically is, since glass is made of the same material.
When an insect crawls across diatomaceous earth, the jagged shells damage the insect's outer layer, and it dies. This material has been used as an insecticide for a century. It's safe for humans although you're advised to wear a mask when applying it , and even comes in a "food grade" form that some people take as a supplement. Best of all, there are no chemicals to get in the soil or end up in your food. Rain washes the dust away and you have taken care of your pest problem organically.
Although the tomato hornworm does have what looks like a stinger coming out of its tail, it's completely harmless. There are some other species, though, that are venomous and can give you a pretty nasty sting if you touch them or brush up against them. Handling caterpillars is fine if you know which one you're dealing with, but otherwise it's best to use gloves or avoid letting the caterpillar contact your skin, especially if it's furry or has spines.
The curved tail or horn on the hornworms's rump is not a stinger, though scientists think it may look enough like one to provide protection to the caterpillar. There is no sting, or even a sharp tip to the horn, so its use as a protective device is debatable.
It has also been suggested that the tail resembles a snake's tongue, or that it draws attention to the back end, sparing the head of the insect from attack. Makes them glow like a lightning bug.
I check my tomatoes, peppers and potatoes. Interesting critter but I have too few tomatoes to share with it.
