Tomato hornworms are most active at dusk, dawn, and at night. The hornworms leave the droppings behind as they munch through the plants. Black DroppingsĬheck your plants to see if you find any black droppings left on the leaves of the plants. If you’re wondering if your plant damage is caused by tomato hornworms or not, here are a few signs. Also, the signs of these pests are similar to other pests. It’s hard to spot the worms because they camouflage so well with the color of the plant. Most gardeners will see signs of the tomato hornworm before finding the larval stage on their plants. The adults also lay eggs, continuing the tomato hornworm lifecycle. They are hard to spot because they aren’t out in the daytime when we are in the garden. This is the adult stage, and they feed on the nectar of different flowers in the evening into the early morning. In the late spring, the pupae hatch, and a large moth comes out, known as the five-spotted hawk moth or the sphinx moth. The last stage of the cycle is the adult stage. When cold weather arrives, they overwinter in the soil as large, reddish-brown pupae. The larval stage lasts around three weeks, and an average tomato hornworm reaches up to five inches long and weighs 10 grams.Ī tomato hornworm is essentially a large caterpillar. This stage is broken down into five stages called instar stages. That’s when you find a huge, fat, green worm on your tomato plants.īelieve it or not, those huge worms aren’t the adult stage, despite their massive size. The adult female sphinx moth lays eggs on plants in the nightshade family, such as tomatoes, peppers, eggplants, and potatoes.Įggs hatch within three to five days after being laid on the plants, and the worms start to grow rapidly. Understanding how these pests grow and multiply is valuable for gardeners. Generally, we only see the larvae stage, but a lot is happening before, and after that, we don’t see. Tomato hornworms have four parts of their lifecycle. Those are the only two differences, so you’ll need to look closely to identify the difference. However, the tobacco hornworm has a red-colored horn and diagonal white stripes instead of v-shaped stripes. So, distinguishing the difference isn’t truly important. They also both prey on nightshade plants, and gardeners treat them the same. It’s easy to confuse tomato hornworms and tobacco hornworms they both come from the same family of insects. No other pest blends in with the plants as well as these. Tomato hornworms are the perfect green color to match tomato leaves. The easiest way to identify that these are tomato hornworms is by their color. The most noticeable stage of these pests is in the juvenile larval stage when the huge caterpillars may be found in your plants, but they eventually turn into a moth with a five-inch wingspan. If you get close to them, you’ll notice large red or black horns that protrude out of their rear. A tomato hornworms look like a green caterpillar that measures around four inches long with seven white v-shape stripes running diagonally on their bodies.
