ABSTRACT Macroplea appendiculata PANZER, 1794 is an extremely rare species in Poland and Europe. This paper provides new data on the ecology of this species. 24 specimens of M. appendiculata were collected in fish ponds at Samoklęski. This beetle was caught mainly with active traps placed on the bottom, but it was not found in traps set just below the water surface. The data show that M. appendiculata is a typical benthic organism, moving vertically to only a small extent. The low rate of metabolism allows this beetle to inhabit waters of varied, as well as low, oxygen content. The occurrence of the most numerous population of M. appendiculata in fish ponds, currently known in Poland, indicates the crucial role of this kind of water body as a habitat for this species.

In countries like India there is always a scarcity for fresh water along with it polluting the available fresh water sources is a major threat. The major fresh water bodies are affected by eutrophication. It is the phenomenon in which algae forms a layer above the water surface and does not allow the sun light to enter into the water body. Due to this reason organisms which is present in the water body gets affected and the ecosystem gets damaged. The algae which are taken from the water bodies is dropped as waste in garbage or let to dry out on roads. “One man’s waste is other man’s treasure” so instead of wasting the collected algae, the algae can be used to prepare a dye which can be used to dye clothes for different uses. The collected algae are used as a raw material in an algal dying machine where the processes carried out are cleaning, drying the algae, grind it, boil them with water and other essentials, filter the residue and finally filtrate will be used to print on cloth.
