ABSTRACT
The liquids in pitcher plants are presumably derived entirely or in part from the plants themselves, making the inside of their pitchers a separate category of habitat and placing the fauna they contain in their own distinct group within the phytotelm. The community inhabiting the living pitcher plants could well be the subject of a study certain to yield interesting results concerning what appears to be a long-standing symbiotic relationship between an insectivorous plant and insect species which help digest its food. Species in the family Chironomidae are best represented among the Diptera which develop in the fluid held in the pitcher plants. In addition to various species of Diptera encountered in the pitchers of plants in the family Nepenthaceae, the case-bearing caterpillar of a species in the order Lepidoptera was discovered in Nepenthes destillatoria Linnaeus on Sri Lanka.
