Hottest day of the year so far here as well, but not quite into the 80's. It has brought this European Peacock butterfly out of hibernation.

I posted this dogwood leaf a couple of weeks ago in the macro thread, but it is now too big for a macro lens to capture. I like the way the colour of the wood matches the flowering currant in the background.

The next two were taken just outside Aberdeen:
5D Mark II, TS-E 24mm f/3.5L II @ f/8, 1/500s, ISO 400 (shifted to keep the verticals upright and tilted to get all the daffodils in focus)
5D Mark II, EF 14mm f/2.8L II USM @f/11, 1/250s, ISO 200
