Conservation and restoration of insect specimens This is done to minimize shriveling allowing the identifying characteristics to be preserved as true to life as possible. Hard-bodied insects may also be preserved temporarily in alcohol before pinning. Slides of very small insects are also kept as part of insect collections.
