The common garden katydid is native to Australia and New Zealand, and is found in the gardens of most of our cities. Adults such as this one are
always green, but nymphs – which moult regularly and still have developing wings – take on the colour of whatever they have been eating: pink,
for instance, if lunch was a hibiscus flower. This colour will last through several moults; it seems much safer, therefore, to have a taste for greens.EAT YOUR GREENS BY STEVE PASSLOW
