They are in the orchard and in the yard. The soft ones are attached to their outer skin, While the hard ones live free within.
Soft scales produce honeydew, But hard scales find it impossible to do.
Legless, the hard ones can't move away. They spend most or all of their lives feeding on plants and are primarily important as plant pests in greenhouses, backyards, and on fruit trees. The objective of this site is to provide comprehensive information on the scale insects of the world, including queriable information on their classification, nomenclatural history, distribution, hosts, and literature.
