Colouring Up...

The few larvae I'm following this autumn / winter are colouring up and wandering off the leaves. Some have undoubtedly entered hibernation - they're hard to find until all the leaves are off. In mild dry autumns they can travel several metres before conking out for diapause. Oh for a cold, wet and thoroughly miserable late October / early November, so that they only crawl a little way - but every year of my study that period has been mild and dry, and larvae have gone walkabout big time...

Here's Savernake No 10 today -



Here's the two main seat and feeder leaves of Savernake No 1, today, dangling from silk strands. This larva is probably in hibernation as it was on an early leaf fall sallow. Note the first / second instar seat pad & feeding marks on the broadside leaf.
