Firebugs (Pyrrhocoris apterus) at the northern edge of their range in the UK. Described as 'nationally scarce' in my fairly recent insect book. They are clearly taking advantage of global heating. These were in Gillingham, Kent, yesterday, on a sunny bank. I will #irecord them as they are easily recognized and are one of several species that can help to track insect range in relation to climate. #insects#ClimateDiary
