Sequence of a pitcher plant pitfall trap in action. We did not detect a decline in negligent reporting over time >1 key methodological detail was missing from >50% of studies regardless of the decade published. Cunning pitfall-traps are perfectly evolved to defeat their light-footed insect prey. Studies published in wildlife journals tended to use pitfall traps of larger diameters than studies published in other disciplines, and they had worse rates of methodological reporting than those in entomology journals. Pitfall trap designs to maximize invertebrate captures and minimize captures of nontarget vertebrates. Pitfall traps provide a convenient method of investigating the ecology of adult Carabidae and have been used in studies on such topics as the seasonal. We found only minor differences in the pitfall trapping methods most commonly used in different vegetative communities (e.g., preservative use was less frequent for pitfall trap studies in grasslands). Pitfall trap methods varied greatly across the time period we investigated.

Two different methods of live trapping are commonly used to catch lizards in New Zealand, pitfall traps and funnel traps. We conducted a literature review to identify the most common methods used by past investigators who placed pitfall traps for the purpose of quantifying indices of arthropod abundances, and we used this information to guide our proposal for standardized pitfall trapping methods. Pitfall trap methodologies and designs vary tremendously among studies and investigators, and this variation and lack of standardization limits scientists’ abilities to compare their results to others. Pitfall traps are commonly used in diet studies for insectivorous and omnivorous wildlife.
