A wet specimen is a specimen preserved in fluid, often 70% alcohol. Specimens that would receive this preservation technique are usually soft-bodied, such as caterpillars, larva, and spiders because of their soft abdomens. This is done to minimize shriveling allowing the identifying characteristics to be preserved as true to life as possible.
Plant collecting is the acquisition of plant specimens for the purposes of research, cultivation, or as a hobby. Plant specimens may be kept alive, but are more commonly dried and pressed to preserve the quality of the specimen. Plant collecting is an ancient practice with records of a Chinese botanist collecting roses over 5000 years ago. [1]
By storing this way, the botanical specimens are maintained in a usable condition by inhibiting enzymatic and microbial attack. [7] This method can be used where drying, pressing and mounting on a herbarium sheet is unsuitable. This method allows for a better three-dimensional arrangement of flower parts or fruits for storage.

To mount the specimen, a tiny amount of glue is placed on the tip and applied to the right side of the insect's thorax. [14] If appropriate the tip of the point may be bent at the necessary angle to hold the body of the specimen horizontal when the pin is vertical, with the long axis of the insect at right angles to the point.
