As cities get bigger and cover more land, the need to make space for wildlife – including insects – in urban areas has become more pressing. Research has shown that cites may not be such a bad place for pollinating insects such as bumble bees, solitary bees and hoverflies. In fact, one UK study of ten cities and two large towns found a greater variety of species in urban areas than in rural areas, while another study showed some UK urban areas hosted stronger bumble bee colonies than those in rural areas.
