Insects struggle to survive in urban areas. The main challenges they face are a lack of green spaces, noise, pollution and artificial light at night.

The German NGO Bonn Science Shop (WILA Bonn) has launched a pilot insect-counting project to evaluate which species are endangered and which can adapt to city life.

Several people have volunteered to help carry out the tricky and time-consuming research. DW sat in on an outdoor bug-counting workshop in Bonn in western Germany.
