17.2. Preservation and curation
Most adult insects are pinned or mounted and stored dry, although the adults of some orders and all soft- bodied immature insects (eggs, larvae, nymphs, pupae or puparia) are preserved in vials of 70–80% ethanol (ethyl alcohol) or mounted onto microscope slides. Pupal cases, cocoons, waxy coverings, and exuviae may be kept dry and either pinned, mounted on cards or points, or, if delicate, stored in gelatin capsules or in preserving fluid.
