Drosera

Drosera, commonly known as the sundew, is one of the largest carnivorous plants. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica. The English common name 'sundew' refer to the glistening drops at the tip of each tentacle that resemble drops of morning dew. 

The round-leaved sundew that I have found in the nearest bog is a specie of this carnivorous plant. It may be found in bogs, marshes, fens and is the most widespread sundew of northern Europe, much of Siberia.

The plant feeds on insects, which are attracted to the glistening drops loaded with a sugary substance, covering its leaves. It 's carnivorous behaviour in response to usually poor in nutrients soils. The plant uses enzymes to dissolve the insects which become stuck to the  tentacles and extract nutrients from their bodies. (wiki)
I first saw sundew in the bog close to the river, where I often walk (read 'All the rivers run'). In general, I was looking for wild strawberries, because they usually ripen in June. 

Lovely wild berries and very sweet.

 
Having read in detail about the behavior of the sundew, I thought that if it were larger and consumed more bloodsucking insects causing harm to people, pets and livestock then mosquitoes and horseflies would not even be in the garden :-)  What is your opinion?
