Gum tree sap. The trees bleed this blood-red sap in reaction to
insect borer attacks. These insects create tunnels and chambers as they
consume the wood. The tree responds by flooding the wounded area with a
chemical called
‘kino’, but it can also be sap or amber. The kino engulfs the insect —
trapping it and hopefully killing it.
