Cabbage caterpillars and moths
The end of the season was pretty bad for my kale this year. The larvae won’t overwinter, right? I’ve read some organic remedies and covering techniques that I will try next season but can you suggest anything else? Thank you!

Thank you for your question. Some types of pupae can overwinter. I think the following 2011 MSU Extension bulletin on "Caterpillar Pests in Cole Crops" could be helpful for you: http://vegetable.ent.msu.edu/wp-content/uploads/Cole-Caterpillars-E3165-1.pdf
Here is another article on the topic from MSU Extension: "Identifying and managing caterpillar pests of the cabbage family" https://www.canr.msu.edu/news/identifying_and_managing_caterpillar_pests_of_the_cabbage_family
