One section is possibly softer than usual.
I'm always fascinated by the holes in that section.
Were they made by bees?
Many seem to have been taken over by spiders.
The largest must be getting on for 3 cm in diameter which seems to me to be rather large for a mining bee.
Any other ideas?
I sometimes see these in old stone buildings - we had them in some of our field walls when we farmed. I have always wondered what made them.
ReplyDeleteI can't think what else could have made them.
ReplyDeleteI would have said mining bees too. Perhaps if the rock is soft? rain and frost etc have weathered the holes to make them larger than they originally were??
ReplyDeleteAfter a bit of searching I found a picture of similar holes which can be seen at the end of this page

A right click lets you look at a larger picture.
They look to be about the same height from the ground as the local ones.
Made by musket balls during the civil war?
Fascinating !
ReplyDeleteWe have 'wood bees' here that bore round holes in untreated wood, a nice secure place to lay their eggs.
