Rachel is on Deeside where a rare and elusive ant which hadn’t been spotted in the area for over 70 years has been rediscovered in large numbers. She hears from the man who found it.

And Rachel also chats to Dr Jenni Stockan, an insect ecologist at the James Hutton Institute who confirmed the ant discovery. She explains the process of identifying insects.

We hear an excerpt from this week’s Scotland Outdoors podcast which features author Peter MacQueen. Peter’s family have a hut in Argyll but to get there, you have to cross a stretch of water by boat or canoe. Mark heads out to visit the hut with Peter and his Dad.

Dundee Museum of Transport is on a major fundraising drive to make their planned new home weather tight. The museum has major plans for the old Maryfield tram depot but before work to relocate can take place, Mark hears about the maintenance they need to carry out.

We have not one but two rare insects on the programme this week as we also hear about the discovery of medicinal leeches in Dumfries and Galloway. Craig Macadam from charity Buglife joins us live to tell us about these fascinating invertebrates.

Rachel is in Edinburgh visiting Rhyze, a community mushroom farm. She hears how the group got started in a shipping container on a former industrial site and what their plans are for the future.

Paul English joins the Inverclyde Time Teamers, a group of enthusiastic amateur archaeology detectives, and hears about some of their incredible finds.

And sticking with archaeology, Mark hears about the discovery of the site of Deer Monastery where it is believed the Book of Deer, possibly the earliest surviving manuscript produced in Scotland, was written. Dr Ali Cameron was part of the dig and she tells Mark about its significance.
