Tomato hornworm caught in the act of defoliating a tomato stem.
Tomato hornworms fluoresce a bit when using a long-wave UV flashlight.
Here is a view of a young tomato hornworm, recently plucked from one of the tomato plants, shortly before meeting its doom. Tomorrow morning, I am going to sweep all the hornworm poop off the deck and then check again tomorrow evening to see if there is more poop in evidence. Then, we'll check the underside of the leaves, nearest the poop, to find the caterpillars and help them meet their doom, repeat, repeat, repeat. I know, I know...I should leave one sacrificial tomato plant for them to chow upon, but, but, but...maybe next year!
