Pitfall Trapping September 2015

Dr. Kim Eichhorst spies a garden spider in the field during one of three annual pitfall trap collecting events. BEMP scientists set pitfall traps throughout the Bosque and then observe the number and type of surface-active arthropods (bugs) that fall in them over 24 hours. This helps tell us more about the ecology of the bosque and how it is responding to wet and dry periods.
