engaged in forming a cage to hold prey larger than a single leaf 

 could hold. Often there are several plants engaged, two or more 

 leaves from different plants forming a cage around a single en- 

 trapped insect. This I have seen repeated in the laboratory 

 when a small piece of chicken liver was placed on one leaf. 



The most important thing to these insectiverous plants is 

 that they should be in the best position for catching insects.

several leaves holding one insect — leaves from two plants 

 with one insect. 



Here the small flying and crawling insects are plentiful. From 

 many observations I do not think that the plant waits for the 

 insect to alight on the leaf, and merely responds by a touch- 

 reaction, but I believe that it makes quite elaborate prepara- 

 tions in advance, and it behaves as though it enjoyed the sport, 

 — Spreading the broad surface of the leaves out side by side and 

 with interlacing tentacles, turning the outer glandular hairs 

 down — and the upper ones up, so obtaining a maximum surface.
