Biological collections preserve plant and animal specimens through various methods. Dry collections involve preserving specimens without liquid through rigidity or highlighting distinguishing features. Wet collections submerge specimens in liquid preservatives to maintain body form and soft tissues. Low-temperature collections maintain specimens' viability for analysis by storing at cold temperatures. Microscopy collections prepare specimens for examination under microscopes. Proper collection, preservation, cataloging and storage help museums maintain valuable reference materials.

7. Attracting Nocturnal Insects With UV Light Many insects can see ultraviolet light, which has shorter wavelengths than light visible to the human eye. For this reason, a black light will attract different insects than a regular incandescent light. . The black light can be suspended in front of a white sheet, giving flying insects a surface on which to land. You can then observe the insects on the sheet, and collect any interesting specimens by hand. A black light trap is constructed by suspending a black light over a bucket or other container, usually with a funnel inside. Insects fly to the light, fall down through the funnel into the bucket, and are then trapped inside the container. Black light traps sometimes contain a killing agent, but can also be used without one to collect live specimens.

8. Malaise traps A Malaise trap is a large, tent-like structure used for trapping flies and wasps. Insects fly into the tent wall and are funnelled into a collecting vessel attached to highest point.
