Snapping modes of Venus flytrap. (a) Synchronous lobe movements either lead to a sudden curvature inversion of both trap lobes (“normal” snapping), or (b) to a snap buckling beginning at the apical part of the trap and progressing towards the basal part. (c) In asynchronous trap lobes, one of the lobes moves first. Time scales are indicated, arrows depict lobe movement. At t = 0.29 s in (a), the trap is in the state defined as the closed state in this article (see Experimental section). Afterwards, the poroelastically dampened closure motion proceeds, but much slower (see timescales).
