Islands & Islets (10): An Inner Hebridean Odyssey ... Caterpillars

The churchyard at Trumpan, Waternish, Skye, where we saw ...

... a Knot Grass Caterpillar (earlier sighting here). 

We spotted this (?White/Buff Ermine or Clouded Buff) caterpillar near ...

... the wonderful Abbey on Iona.

Do let me know in the Comments section if you can help with the identification of the caterpillar on Iona! Thank you.
