Half-coloured-up larva photographed yesterday. 50% of larvae are in a similar colour state, though none is more advanced and some are still in their late summer Lincoln green. Note that the normally yellow projections on the dorsum of the 4th abdominal segment have turned a rather nice orange colour. What are these projections called and what is the point of them?
