Collection and preservation of arthropods is important in biodiversity studies. It enables researchers, scientists and enthusiasts to study, identify species and understand their ecology. 

The methods used to collect arthropods are dictated by the ultimate goal of the samples collected. For example, sampling may be conducted to measure biodiversity to help identify appropriate areas to be included in reserves. 

Sampling aquatic species may help to detect changes in water quality. Pest species may be sampled to assess their presence, absence or abundance in order to determine whether control measures are necessary.
