Many years ago I found some rather interesting insect egss that were laid on my nursery trees. Usually just a couple of trees out of all them. They seemed to be laid in alternatining pairs of eggs slightly overlapping each other. They were always cream colored. I took a pair of forcepts and squeezed each egg destroying them all. I later learned from International Bonsai Master Larry Jackel, Curator of the Denver Botanic Gardens, Bonsai collection that these were the eggs of a Katydid. Katydid are very similar looking to a grasshopper but much more elegant insect. They are also much easier to catch then a grasshopper. An adult Katydid can be reather large somewhere between 2-3 inches in length. The ones I find in my yard are always a bright pleasent green and the wings are the same color. Yes, they do fly pretty good with those wings. In rearching them I did find out they do eat plant material. I really do not know how much damage they do to my trees since I hardly ever see and adult let alone a nymph. I honestly cannot tell you what I do with an adult since I don’t see/find them that often. I find the egss much more then I do the adult insects. I occasionally do see a small green insect that might be a tiny Katydid or maybe a male Praying Mantis which I do have in the yard as well.
So for the most part I do nothing about them. I thought I would post some photos of the eggs in case someone else wants to know what they are should they run accross some in the yard.
