Tiny Tuesday - Lichen on Granite

Rik's on a week's toil again so we've been out and about today. This morning we did a short walk near home and this afternoon we walked near Corbiere Lighthouse. My main blip for  Tiny Tuesday's Mineral challenge is of a granite boulder covered in lichen. In extras is a brown argus butterfly just like one I blipped just over a year ago when one was visiting my lavender plant.

Thanks to ninniex for hosting this month.
