Tetranychus urticae is part of a group of very similar species in the genus Tetranychus. Tetranychus urticae ingår i släktet Tetranychus och familjen Tetranychidae.

It performs differentially on diverse host‐plant species. As a result it is considered one of the “most resistant species” in terms of the total number of pesticides to which populations have become resistant, and its control has become problematic in many areas worldwide.
