Hummingbird Moth Caterpillar, Hemaris diffinis – Facts and Myths

There’s More Than One kind of Hornworm – Don’t Kill the Good Ones

Don’t kill that hummingbird moth caterpillar – it is NOT the tomato enemy you might think it is.

We’re dealing with two different caterpillars. One is good for your garden, the other one is not, especially if you’re growing tomatoes.

Every year we go through this conversation that begins with people talking about hating to kill the tomato hornworms because they love the hummingbird moths. A flood of comments ensue on what people do — or do not do — to these, but one thing in common is that most people in these conversation threads think that the tomato hornworm turns into the hummingbird moth.

MYTH: The tomato hornworm does not turn into a hummingbird moth.

Helpful Tips for your backyard garden.

There are many reasons to grow a garden and there is nothing like a home grown veggie!  All gardening begins with a plan. The desired site for your garden should have at least six hours of direct sunlight a day (bigger harvest and better taste!). The soil should be loose for root movement; it should also be well-drained to prevent root rot.

Crops must be spaced properly to prevent overcrowding which actually leads to less production. Why? The plants compete for the sunlight and water, and there is no room to grow if not spaced properly. A New Hampshire seed chart can help you make the proper decisions on planting times, harvest dates, and distance between plants which can lead to a successful garden.

Plant your peas, potatoes, cauliflower, broccoli, brussel sprouts, and cabbage at the end of March, early April. These are all cool weather veggies. Tomatoes, Peppers and Cucumbers need warmer weather to grow. If you don’t want to start from seed you can buy the starter plants at most Garden Centers at the beginning of the season. If you need an activity to do with your children get your seeds started inside. Here is an article to help:  We sell both Coast of Maine Sprouts Island Organic Seed Starting Soil and Miracle Gro Seed Starting Mix.

Some helpful tips:

  1. Plant in a sunny location. Vegetables need at least 6 hours of direct sunlight per day. The more sunlight they receive, the greater the harvest and the better the taste.
  2. Plant in good soil. Plants’ roots penetrate soft soil easily, so you need quality garden soil for needed nutrients. (We recommend Bumper Crop Soil made by Coast of Maine)
  3. Space your crops properly per seed packet instructions. Plants set too close together compete for sunlight, water, and nutrition and fail to mature.
  4. Buy high-quality seeds. A few “extra” cents spent in spring for that year’s seeds will pay off in higher yields at harvest time.
  5. A vegetable garden about 16 x 10 can feed a family of four for one summer.
