This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

Leaping Back into the UK Fauna
The Great fox spider (the picture is actually a relative, rather than the real thing) is a large (5cm) member of the wolf spider group that had been assumed to be extinct in the UK for 27 years ( https://www.theguardian.com/environment/2020/oct/31/huge-spider-assumed-extinct-in-britain-discovered-on-mod-site-aoe). Wolf spiders dont make webs but act as ambush predators, leaping on their prey (e.g. beetles and other spiders). They then inject venom and liquidise the prey's contents before sucking it dry. The Great fox spider hunts at night in rough, sandy areas, which is a possible reason why it has been so elusive. The species was recorded, in 2020, on Ministry of Defence land used for training purposes. Such locations, where access by humans is limited and agriculture banned, can provide surprisingly good protections for rare species.
