Camouflaged

I only see these butterflies when walking on stony paths through the pine woods to the belvedere. They are difficult to spot until they fly off whether they are on a path or on tree bark.  We had enough to ring six bells this morning but only had a congregation of nine. Quite a few people are not confident enough to return despite all the precautions.  Mask wearing is obligatory and it was uncomfortable wearing it for an hour. This afternoon I have to learn a method for a virtual ring tonight before the social quiz and a planned FaceTime call with C. and C.
