The present study is conducted to find out the changes in the feeding habits of springtails, related to their ecological habitat. In this study the results and the observations are compared of the diet of Collembola in three different ecological system viz. (1) tropical forest in Topchachi, Dhanbad. (2) two crop fields in Bhuda, Dhanbad and (3) the epiphytic plant, Tillandsia violacea from a temperate forest in Panchet Dam, Dhanbad. Specimens collected from the crop fields have vegetable matter and fungal conidia in their gut contents. The species associated with the epiphytic plants, showed a distinct type of feeding. In such species, the debris of algae, diatoms and bacteria were found. During the dry season, there were fragments of Prostigmata and Astigmata(Acaridae), mites in the gut of Ptenothrix marmorata .In Seirapurpurea, both in rainy season and dry season, there were fragments of exuvia of springtails and also some parasitic nematodes. The presence of mites in the digestive tract of Collembola from the epiphytic bromeliads could probably be explained by the fact that during the dry season, the populations of Astigmata and Prostigmata are enormous and constitute prey for the spring tails. It is also probable that their ingestion is accidental, or even that they are forced to diversify their diet when the conditions of the ecological niche change.
