*The Droseras are real eatch-flies. If examined, especially iu the moruing, a 

 number of the leaves will be found to be folded or rolled inward. These closed 

 leaves contain, usually, from one to three or four minute winged insects, which the 

 leaves have caught and will hold tightly clasped until their substance has been 

 absorbed by the plant. In one instance the commencement of this operation was 

 observed when a fly larger than an ordinary house fly was the prey. In this case, 

 while the fly was resting upon the surface of the leaf, sipping the glittering drops of 

 nectar, a single glandular bristle on each side of the leaf was gently bent over on to 

 the back of the fly and held it down, which operation was followed, no doubt, by the 

 pinning down with more bristles and the closing of the leaf, when the capture would 

 be complete, but unfortunately the observer could not wait for the final result.
