Small and often highly mobile, insects and other arthropods can be difficult to identify in the field.
Correct identification is essential when planning a management strategy, as not everything that is found when sampling a crop is causing economic damage. Mistaking beneficial insects for pests can result in both an unnecessary application of pesticide (wasting time and money), and the potential reduction of natural predation or parasitism, increasing the possibility of an actual pest outbreak.
