UK insects struggling to find a home make a bee-line for foreign plants


Non-native plants are providing new homes for Britain’s insects – some of which are rare on native plants, a new study has found.

Researchers at the University of York discovered that foreign plants – often found in our gardens and parks – were supporting communities of British insects, including pollinators like butterflies, bees and hoverflies as well as beetles, bugs, and earwigs. For example, native Loosestrife weevils were commonly found consuming the non-native European wand loosestrife, and solitary bees were found visiting the flowers of non-native agave-leaved sea holly plants. 

Man-made habitats 

Lead author PhD student Roberto Padovani, from the Department of Biology, said: “We are rapidly altering the face of our planet, and creating more and more man-made habitats which are providing unexpected homes for nature, and in this case, it is foreign plants supporting the UK’s insect communities.”

“It was fascinating to observe the diversity of insects on non-native plants, from pollinators to bugs like crickets and lacewings and beetles like ladybirds and weevils.” MORE
