I think what you're dealing with are Pear Slugs, which may or may not be what Beeman mentioned above. I used to see them on my pear trees and would just squish 'em when I found them. I don't see them anymore. In small numbers they didn't seem to do much damage, just mining the leaf surfaces here and there. They are a serious pear pest though in other parts of the country. Here is a link that might be useful: Pear Slugs

Did they tell you how the root the plant from cuttings? Viburnums are generally not too tricky to propagate from cuttings but there are techniques that will definitely enhance your chances of success. Timing. Ideally you want cuttings in the softwood stage - the tip of the branch bendable but not so bendy that it does not snap off. So any time from late spring through summer. You want a tip cutting that has at least two sets of leaves - about 3-5" in length. And preferrably no flowers (if any, cut off). Make the cut about 1" below the second set of leaves - strip these off. Dip in rooting hormone then plant in a well draining starting medium with the lower leaf nodes below the soil. Cut the remaining leaves in half to reduce transipration. It helps a lot if you place the starts in their pots inside a clear plastic bag to prevent evaporation, keeping the plastic off the leaves. Bottom heat, if you can provide it, will hasten root development. Provide room temperatures - right around 70F is good - and keep out of direct sunlight. Keep the potting medium moist but not wet. Rooting should occur in about 4-6 weeks. Once firm rooting has been established, the cuttings can be planted up into a larger pot. But it will take time for a proper root system to develop and you may not be able to plant them out in the garden without protection for a couple of growing seasons. A greenhouse or cold frame would be helpful. Can't say how likely your cuttings are to take this late in the season but it is always suggested to expect a fair percentage of failure at any time. IOW, take a whole lot more cuttings than you think you need :-)

Although it produces semi-woody stems during the growing season, Gaura is considered an herbaceous perennial and will typically dieback to the root crown or a basal rosette of foliage in winter. It is very particular about drainage and heavy or very damp soils in winter can result in it not reappearing again in spring. Otherwise, it is moderately cold hardy - zone 5.

No offense taken. I am uploading new pictures. Two different trees. I hope you guys will help me to I.D. both of them. By the away, thanks for your help. I live in Phoenix, AZ. Zone 9, I think. I hope the leaves hill help to I.D. the tree. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 2 Tree
