Set pit traps in a wooded area, an area with tall grass, weeds, and wildflowers, and a manicured grass lawn to compare how the arthropods you catch differ. STEP 8: Try to identify the arthropods you captured in your pitfall trap. Set the arthropods free where you caught them. Record its approximate size and draw it in your science notebook. STEP 7: Observe each arthropod with a magnifying glass. Gently shake what you catch onto a white cloth or towel.

STEP 6: Check your trap daily to see what falls in. This will protect whatever falls into the pit from drowning if it rains. STEP 5: For a protected trap, set rocks around the edges of the container and place a lid on top to make an elevated roof for your trap. STEP 4: Camouflage the edges of the container with leaves, if you want. STEP 3: Place the collection container in the hole and fill dirt around it so that the top of the container is flush with the surrounding soil. STEP 2: Use a trowel to dig a hole a little deeper than your collection container. Gardens and areas near trees and plants are good places to sample arthropod populations.

STEP 1: Select a spot for your pitfall trap.
