Already beset by degraded landscapes and a toxic environment, insects are going to suffer a catastrophic decline in numbers unless climate change is controlled, according to new research from the University of East Anglia. This is on top of the alarming collapse reported in Germany, where 75% of the flying insect biomass has vanished from protected areas in less than 30 years.

Insects are the backbone of a healthy ecosystem and the consequences of their absence will be global. Is there anything we can do other than despair? Insects will need stepping stones to move around the country as the climate changes. Here are some ways you can help.

If you have a garden, make it part of the solution. Insects need food and we have destroyed 97% of our wildlflower meadows. The charity Buglife has a great guide that shows which plants help which insects: winter flowers such as hellebore, erica and mahonia for pollinators such as bees; evergreen shrubs and climbers for bugs such as woodlice and spiders.

Insects need water – make sure you have some in your garden. Watching bees drink at the bird bath is fun; better still is watching dragonflies emerge from your wildlife pond.

Look beyond your own patch and lobby your council to turn verges into highways for insects. Plants help insects, which help mammals, bats, amphibians, reptiles and birds to thrive. We need to fix the system, not just an isolated component.

B-Lines, a series of insect pathways running through the countryside, are the best way to help on a national scale. You can help by writing to your MP and asking them to support Ben Bradley’s Protection for Pollinators bill. The “B-Line bill” will make the Department for Environment, Food and Rural Affairs take this innovative landscape ecological solution seriously. It passed the first stage of the process through parliament unopposed.
