Early life and career

Dacke went to high school in
Landskrona Landskrona (old da, Landskrone) is a town in Scania, Sweden. Located on the shores of the Öresund, it occupies a natural port, which has lent the town at first military and subsequent commercial significance. Ferries operate from Landskrona t ...

on ''Celestial Orientation in Dim Light'' in 2003, under the supervision of Professor Dan-Eric Nilsson. Her thesis focused on how optical compasses are built, how they are used and how they are adapted to work at low light intensities. During her Ph.D, she discovered a unique compass organ in spiders, a study which was published in ''Nature'' in 1999. A few years later she revealed the first evidence of an animal able to use the dim pattern of polarized moon-light for orientation, a study also published in ''Nature'' in 2003. After her Ph.D., she spent two years as a postdoctoral reseacher at the Centre for Visual Sciences at the

in Sensory Biology in 2017. Dacke's research is focused on navigation and orientation in insects, in particular orientation in dung beetles. She is interested in the celestial compass (which is the use of the sky to guide navigation). By exploring the interface between behaviour, neurobiology and cognition, her research tries to understand how diurnal and nocturnal compass systems of insects work. In 2013 she, together with Marcus Byrne, Emily Baird, Clark Scholtz and Eric Warrant, received the Ig Nobel Prize in the joint astronomy and biology category for showing that nocturnal dung beetles can use the
