Coldfall Woods is one of five ancient woodland areas in Haringey. It currently covers about fourteen hectares of land, but used to be twice as big during the twentieth century. The wood is dominated by oak trees and hornbeam coppice, and not much else. But while the plant life is not very diverse, a survey back in 2009/10 revealed a wide variety of invertebrate insects, including rare species such as the pseudoscorpion and lesser glowworm. The pseudoscorpion is in fact an arachnid because it has eight legs. The lesser glowworm is a type of firefly, and the only one that is unable to fly; perhaps this is why it is so rare - because it can't get around as much.
On the 7th July at 2pm, you can join Tristan Bantock, an entomologist and recorder from London Natural History Society, on a search for these illusive creatures, and many other insects on an invertebrate walk at Coldfall Woods. It is free, but any donations (a suggestion of £3) are appreciated.
