I used to let them go because I like the noise they make. I caught them eating my daylily flowers more than once. Now I squash them.

I had a Barnes and Noble 15% off on top of my member discount. Last night, I went and got a book I've seen before and wanted. It's called, "Garden Insects of North America" by Whitney Cranshaw. In it, I found the answer to my questions.

I found out that grasshoppers, crickets, and katydids are in the order called, "Orthoptera". Cranshaw says that katydids are usually large grasshoppers with long antennae and thin jumping hind legs. There are different kinds. Here's a quote from the book, "Both the nymhs and adults chew leaves, rarely causing noticeable injuries." I'm still keeping an eye out, because today, a whole section of a flower was gone from the flower the katydid was in. Maybe that wasn't the culprit, though.

Happy gardening and nature watching,

Oh yes... it is the katydid. They don't do much when they are little and cute, but then they grow up and eat the petals AND your pollen. Trust me, I watched them do it. Buggers!! I am sure there are other bugs that do this as well, I think people have mentioned here slugs and maybe earwigs too... but for me, it is totally the katydids.

No Katydids here, at least not that I have noticed. But the slugs have been having a great year, yeck.

They cause minimal damage, bug look how cute the little nymphs(juveniles) are!
