There were several zebra spiders Salticus scenicus running around in the sun on my allotment shed door this morning. This one is on the hinge.
 This one is about to inspect a nail hole
 This is a male with his extra-large mandibles. Note the fangs folded underneath, like flick-knives.
 A typical pose, ready to jump
 Hard to spot, but the four points of light on the dark stripes on top of the head are backwards-pointing eyes
Sight hunters with excellent vision, this one seems to be fully aware of the camera lens.
Looking forward to seeing what these little chaps are up to if we get more sunny weather. Maybe I’ll be able to observe their ‘semaphore’ courtship displays. 
Look out for them on sunny inside windowsills.
