Oranges and lemons

Congratulations on the century, Dave, and I hope the year continues to go so well. Here, I'm pleased to have a different part of the spectrum with an Orange Footman and my first Brimstone of the year (nice to have so many of their beautiful butterfly namesakes plus Orange-tips around in the sunshine too). May I just check my pug, which I'm guessing is Brindled?  Martin Wainwright, Thrupp, Oxon
