a:  A large insect’s second contact with the plant’s trigger hairs results in a total calcium ion concentration above the trap’s threshold. ;
 A large insect makes contact with a second trigger hair after a period of inactivity during which calcium ion concentrations have diminished appreciably. ;
 A large insect’s contact with the plant’s trigger hairs causes calcium channels to open in the trap. ;
 A large insect’s contact with a second trigger hair occurs within ten seconds of its contact with the first trigger hair. ;</description></oembed>
