Can we estimate insect identification ease degrees from their identification key paths?

Identification key represents a powerful tool, which allows users to identify biological species, such as animals, insects, and plants. This key contains several steps leading to the corresponding species name. In this paper, we propose a new method for estimating insects' identification ease from their charecteristics values (CV). To realize that, we have investigated; 1- the variations of the identification ease level (IES) of the SPIPOLL insects, 2- the relation between the CV and the IES. The obtained results showed that the CV can be used to estimate the IES of the SPIPOLL insects. •Identification key represents a powerful tool.•In the SPIPOLL, users use an identification key to identify insects.•We investigate the relationship between the identification key path and the insect identification ease degree in the SPIPOLL.
