Several projects are still using white flashed, definitely those who want to make use of individual identification (by using spot patterns on coat). Male earwigs have curved pincers, while females have straight ones. Pitfall traps are more effective for collection of ground dweller amphibians and reptiles having less jumping and climbing ability. It produces an "index" by which several geographic locations can be compared. We conclude that the correction of the species-specific pitfall trap sampling bias is necessary for the reliability of conclusions drawn from ground arthropod field studies. Cannot be used in many urban and semi-urban areas as they need to be dug into the ground. Read, J.L. The disadvantages of pitfall traps are: A return visit is needed (to dig traps in, and then pull them out) A limited number of sites can be visited in a single day.
