[Display omitted] •Carabid abundance estimates from pitfall traps are biased by body mass.•We tested whether a method based on hand collecting is less subject to such bias.•Abundance estimates from hand collection are less size-biased.•Hand collection abundance estimates may also be entirely unbiase...
