Pitcher plant and beetles
Numéro d’image : 11533828
| Beetles,Cetonia sp poised to fall into the trap of a carnivorous pitcher plant,Nepenthes madagascanensis. The pitcher (up to 30cm high) is an elaborate extension of the midrib of the leaf,which forms an insect trap. Its bright colours (often red) & the scent of nectar attract insects. The lid,closed during early development,opens at an angle to prevent rain filling the urn. Insects fall into the pitcher & drown in the sugary liquid produced by the plant & which contains digestive enzymes. Their digested bodies provide nitrogen compounds & proteins to the plant,which are absent from the poor soils they grow in | |
