Reports of sightings of bumblebees are being sought by a conservation group.
Bumblebees have already been spotted in Stirling
An early start to spring has seen the insects emerge at the University of Stirling campus, where the Bumblebee Conservation Trust is based.
The organisation hopes people will send them digital images of any bumblebees they spot to help monitor activity.
The trust has been involved in various initiatives to boost numbers, including projects to aid the great yellow - the rarest bee in the UK.
The species clings to survival in areas of the Highlands and Islands.
Experts fear numbers could be harmed by a return of wintry conditions.
Last year's wet summer had a "dramatic" impact on ground nesting bumblebees, according to the trust.
Rain-sodden ground and moss can be a threat to certain species.
