I’ll have to remember that. One of my tomato plants has hornworm damage, but I couldn’t find the worm itself.
They are VERY hard to see. they are exactly tomato plant color and on the underside of the leaves. I found most of them in the evening because they are supposed to come out at night to feed.
MOST the ones I found were HUGE, which means they were ready to pupate and breed again. I found a few smaller ones, but not many. I expect another infestation but hopefully, the tomatoes will be done by then.
If you google up the hornworms, there’s a plethora of information about them. Basically, you kill them to stop them.
I can’t bear to touch them, even with gloves, so I have clippers and snip off the leaf it’s on and toss it in a bucket of soapy water.

Go out in the evening and gently shake the tomato plant and listen for a clicking sound if you can’t see them and look deeper...
