Japanese beetles are attracted to Four O'Clocks and eating the plants are fatal to the beetles too. I plant Four O'Clocks up and down my drainage ditch to keep the JP's numbers down. It seems to work pretty darn well.
Moths in general are attracted to flowers with scent. There are many types of Sphinx Moths which the tomato hornworm is only one of them. Not all of them are pests and need to be destroyed. In fact I actually enjoy having most of them around. They are fun to watch hovering through my gardens.
