I've found some mystery red spots.........no, no, it's not what you're thinking..... I'll start again!
I've noticed that a few of the butterflies that I've photographed recently have some prominent red spots/ swellings on their bodies. I've not seen anything like this in previous years, and after doing some research I'm still no nearer solving the mystery as to what they might be.
Over to you!
