In spite of the devastation caused by these guysI managed to have some ripe tomatoes they didn’t get to. I learned a lot about horned worms. One book said you have them pick them off and smush them. Not smash, but smush. So the red-orange tomato is a Beefsteak Heritage Tomato. I also found from talking to my green grocery that volunteer tomatoes are healthier and tend over-all not to have insects. Last year most of my tomatoes were volunteers and I don’t remember even one worm.
Horned worms are the result of a white moth that comes at night. I am not out at night but there is a small white moth flitting through my vegetables during the day. I was told that if you plant collard greens the worms will go for the collard greens and leave your tomatoes alone.
