Obtaining unbiased samples of aquatic and terrestrial invertebratesfrom wetlands provides unique challenges due to the varied life history strategiesof invertebrates as well as the heterogeneity present within a wetland. Manysampling devices are useful in more than one sampling environment within awetland but the effectiveness of most methods varies among and within wetlandsas well as between users. In this chapter, we emphasize field collectingtechniques and address laboratory sorting methods. When possible, theadvantages and disadvantages of each method are listed and suggestions areprovided to reduce bias and unwanted variability in sample collection. Samplingdevices for benthic (grabs, single and multiple cores, nets, and artificial substrate),water-column (open cylinder, emergence trap, activity trap, sweep net),epiphytic (box samplers, quadrat samplers), flying terrestrial (aerial net, flightintercept trap, light trap, malaise trap), and non-flying terrestrial (sweep net,aspirator, vacuum sampler, Berlese-Tullgren funnel, mist net) invertebrates arepresented and discussed
