Hi Ian,

There is a caterpillar called the Macadamia flower caterpillar which feeds on the buds and flowers. The chewed pieces of flower are webbed together. If the infestation is heavy the few fruit will be set. Have a look at the flowers to see if there is any webbing present. Yates Success Ultra is effective against a range of caterpillars.
