Close! Looks like scale insects, which are in the same family, in different parts of the lifecycle. They don't appear to move, often. Once they are in their adult stage, they seal themselves to plants. This can be very difficult to treat. Sometimes heavy pruning will be in order, unfortunately.

An internet search will reveal many, many species of scale. Many do not resemble each other even closely, but the treatment will be the same.
