New species of jumping spider found on university campus in Cornwall

Exotic spiders flourish in Britain helped by the effects of global warming and international trade

Some are small and jumpy; others are large and intimidating – if you’re a humble housefly. Exotic spiders are flourishing in Britain as international trade offers ample opportunities for spider travel and global heating provides an increasingly hospitable climate.

A jumping spider new to science has been identified living on the University of Exeter’s Penryn campus in Cornwall. The nearest known relative of the 3-4mm-long Anasaitis milesae is found in the Caribbean, making it highly likely that this tiny species – alongside 17 other non-native jumping spider species – found its way to Britain from distant climes.
