Holidaymakers have been asked to help find one of the UK's rarest bumblebees.
The Bumblebee Conservation Trust has launched The Great Big Great Yellow Bumblebee Hunt in an attempt to spot the great yellow bee.
The insect survives in parts of Scotland including Tiree, Uist, Harris, Lewis, Orkney, Shetland, Sutherland and Caithness after suffering a dramatic decline in the 1960s.
Conservation officer Katy Malone said: "We need to know more about where the great yellow bumblebee is holding on, so we can take action to protect it before it's too late.
"Anyone can get involved with this citizen science initiative to save a species."
She added: "Because this iconic insect's last havens are in some of the country's most far-flung corners, we don't have enough volunteers to find and record its whereabouts.
