but even within one species and also different parts of one trap. Using an electronic position sensor to monitor trap thickness showed that in two clones of Utricularia dichotoma,
both firing (41 ± 2 and 46 ± 3 m mm−1) and resetting rates per unit trap length (14 ± 1 m mm per 30 min) were markedly lower than the mean values for 13 aquatic Utricularia species obtained from the literature (73 ± 2 and 52 ± 2 m mm−1, respectively)
