Scientists use 'mini backpacks' to study rare beetle

Scientists have put "mini backpacks" on rare beetles, which are found in temperate rainforests, as part of a study.

These "backpacks" are quite different to the ones you might take to school, they are actually radio trackers which record where the insects go.

Researchers from the University of Exeter have been working with the Woodland Trust - a charity that helps protect trees and woods in the UK - to take a closer look at the blue ground beetle, that lives in south-west England.

The team said the study could help give an "essential" insight into how conservationists could protect and restore rare habitats like this from climate change.

Researchers often worked at night as part of the study

The researchers were led by Dr Nick Royle and PhD researcher Brogan Pett.

In total they put 36 of the devices onto the blue ground beetles to record their movement across woods in Dartmoor.

Some of the beetles were faster, while others were more adventurous and would travel for multiple days before returning back to their base.

Dr Royle said very little is known about the insects "particularly how it uses the habitat it is found in and what characteristics are essential for it to thrive".

Sam Manning, who is the Woodland Trust site manager of where some of the study took place, said the findings will help with future decisions on how to protect these rainforests.

He said the beetles are an important sign of a healthy temperate rainforest in south-west England.

He believes the study will help find out what the insects need to thrive and repopulate.

The Woodland Trust is working with groups in the South West, Scotland and Wales to help protect the temperate rain forest environments.
