Nature Notes: Leaf Beetle

Chrysomela populi is a species of leaf beetle who specialise in feeding on willows and sallows and can do quite a lot of damage to their host trees.

The larvae have a defense mechanism that's very stiking. When you touch them, they push up their abdomen straight into the air and press out small drops of a liquid that smells like carbolic acid through their pores. If nothing happens, the drops are absorbed into the body again and the larva relaxes.
