The researchers at the Biodiversity Unit of the University of Turku are specialised in studying poorly known species habiting some of the most remote places on earth. As a result of their scientific expeditions, the researchers constantly discover species that are unknown to science. One of the most recent discoveries is a spider which was named after actor Joaquin Phoenix and his famous portrayal of the Joker character.
A study led by the University of Turku has found that small, fiercely predatory damselflies catch and eat hundreds of thousands of insects during a single summer – in an area surrounding just a single pond. In terms of weight, this equates to a total prey mass of just under a kilo. Dragonflies mostly catch different kinds of midges, but also large numbers of other insects.
