There are 59 species of native British butterflies. About two-thirds inhabit the countryside. the others inhabit our towns and cities. For decades now the populations of these butterflies have been recorded. In April 2017 a report in the Ecological Indicators informed us that populations of our rural butterflies was down by 45% and our urban butterflies down by a staggering 69%. It is, then, not inconceivable that in the next few decades our urban butterflies will have disappeared from our towns and cities.
