These curious rocks occur at Redend Point between Middle and South Beach at Studland Bay in Dorset, England. I have featured them several times in the blog before. The bright red and yellow patterned sandstones are Eocene Creekmoor Sand (also known as Redend Sandstone) and are part of the Poole Formation in the Bracklesham Group. The sandstone is very soft and easily eroded. It is also easily carved and provides a surface for much graffiti. However, the busiest carvers are small bees which excavate burrows in which to lay eggs. Now the sandstone has weathered away you can see the empty pupal cases from last year.

Thank you, Jo. I think I have a video of bees buzzing around holes like this in cliffs – I’ll see if I can upload it.

Maybe age, time, and curiosity have something to do with it.
