Sycamore lace bug
The sycamore lace bug is a tiny milky-white bug with wings that look like delicate lace. It lives under the leaves of plane and sycamore trees and sucks their sap. When there are lots of them, the leaves get pale speckles and fall off early.

Fun facts
Its babies look nothing like the grown-ups. They are black, flat and prickly.
It spends the winter as a grown-up hiding under flakes of bark and can survive cold down to minus 24 degrees.
In Europe it was first found in 1964 in Padua, Italy, and it has spread a long way since then.
In summer, it takes about 44 days to grow from egg to grown-up.
You can spot where it lives by the tiny black droppings and old baby skins stuck under the leaves.
