I spent some time in and around London in early December 2025 to attend the Fantastic Futures 2025: AI Everywhere, All at Once at the British Library. I spend most of my time in London proper, but did have a few side-trips to Richmond and Greenwich/New Cross.
At right is a Missing-Sector Orbweb Spider (Genus Zygiella):
Zygiella is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1902. In 2015, Parazygiella was determined to be a taxonomic synonym of Zygiella, and its species were moved to Zygiella.
Identification
Zygiella species are distinguished by the structure of the web, which has a missing sector containing a signaling thread leading to a retreat. Zygiella x-notata, a species in the Zygiella genus, is well-researched for its missing-sector web construction behaviors. -- iNaturalist
