Plane Lace Bug: A Delicate Micro Menace Concealed in the City
On the 25th of July 2024, a public observation was made on iNaturalist of an interesting tiny bug found on someone’s bag in central London. A scientist from Defra spotted the report and gathered more information from the informer, believing it to be a specimen of the plane lace bug (Corythucha ciliata) due to its lace-like appearance and the location of the find in central London, where London plane trees abound.
