Sitting under my small oak tree (now about 25 years old), I became aware of how many small life forms exist on the leaves and also on the logs piled up nearby. First, a very small leafhopper (Ribautiana debilis), then a small booklouse family insect (Ectopsocus petersi) and a Pea gall caused by a small parasitic wasp. The logs are alive with life including Collembolid species and lots of fungi and lichens
