The nectar seeker is forced to 
position itself between the trap lobes.  Three pairs of innocuous-looking 
bristles grow on the inner surface of the lobes. The visitor to the Venus' diner 
has no way of knowing what will precipitate if these sensitive hairs are 
disturbed.  
 
  
When the trigger hairs on the inner surface of the trap lobes are stimulated, 
the clam-shell-shaped trap closes suddenly --- often in less than a half second 
--- fast enough to capture such agile insects as a fly quite comfortably. 
Intermeshing marginal spines effectively prevent the prey's escape. After the 
initial rapid closure, the insect's struggle inside the trap further stimulates 
the trigger hairs, causing the trap lobes to close even more tightly.  In a 
day or so, the trap is seen tightly sealed around the free margins of the lobes, 
with the marginal spines pointing outwardly. The digestive fluids start to ooze 
into the now sealed trap cavity. As the digestive process progresses, the 
products of digestion
