Moths were consistently able to escape, and all left impact spots where scales had stuck to the web. Eisner found these spots to be common. (Eisner 2003:218-220) Scales also help increase the lift to drag ratio in gliding flight.

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. The American Institute for Conservation (AIC) describes in their Code of Ethics the aspects of conservation to include: preventive conservation, examination, documentation, treatment, research and education. Each of these areas also apply to the conservation and restoration of insect specimens. Insect collections may suffer multiple types of degradation including fading colors from light exposure, mold growth from
