Spindle Ermine Yponomeuta cagnagella (Hübner, 1813)
Status .....Common across Nottinghamshire, wherever Spindle Eunoymus europaeus grows. The larvae are present annually in large numbers on any example of the hostplant and can construct huge webs covering whole lengths of hedgerow, as the larvae move to look for fresh food. These become obvious to the public and many become alarmed at the site, but both the larva and webs are completely harmless to the public. Once pupated, the web breaks down and the plant regrows quickly, so that by late Summer, there's little evidence of the earlier infestation.
