Answer 2

B. collecting, killing, pinning is the correct procedure to follow the preserve insect

Explanation:

1.Insects are preserved in insect boxes by collecting the insects from their natural habitat, killing those insects and then pinning it on the box carefully.

2.The insects are pinned through the middle of the thorax, slightly in the right position of the bodies. The insect should be carefully laid out with its wings and other body parts spread out and the pin should be pushed all the way into the insect's body

3.Pinned insects are “preserved” through dehydration. Insects are covered with an exoskeleton made of chitin, a stable macromolecule. A pinned specimen will dry to the humidity level of the room and, if kept in low humidity, will undergo little to no further decomposition.
