There are purportedly 59 extant species of butterfly in the UK. Those marked with an asterisk (twenty, as of April 2025) are ones I’ve yet to record here. There is at least one species that may be recolonising, Large Tortoiseshell. There are others that turn up sporadically, vagrants and migrants and don’t breed here.
