Horse chestnut trees can grow to great heights. A joy to those who collect conkers or like a lot of shade. Around the 1960s the horse chestnut scale (Pulvinaria regalis) arrived in this country and began to spread. It liked other trees as well, especially limes and maples. Local councils and the public soon became aware of Pulvi's presence by the cotton wool like waxy covering produced by these insects along the branches. This story is about one such insect whose short life involved a lot of travelling.
