What is the life cycle of cicadas?
The shortest estimate of the greengrocer’s nymphal lifespan is about four years. ‘[There is] more and more pressure for PhDs to finish in three years, so if you have a three or a nine year, or like the US cicadas a 17-year lifecycle, you’ve got to be pretty patient with them,’ says Dr Popple.

They survive just long enough to reproduce. After all of those years underground, adult cicadas live only a few months. Females lay their eggs in the trees. The next generation of cicadas then hatch and drop so they can burrow underground to begin the lengthy process of maturing into adults.
What kind of cicada is a green grocer?
Most “green” cicadas like our GG (Green grocer – Cyclochila australasiae) are coloured from the mixture of yellow and blue pigments. It is quite common for the blue to be missing to various degrees in GGs, and they exhibit shades of lighter green to yellow (even close to orange) and are then called “Yellow Mondays!”.

How long does a cicada live in an egg?
Their median total life cycle length is around six to seven years, this being from egg to a natural adult death. Most of this spent as a nymph. The cicada spends seven years in nymph form drinking sap from plant roots underground before emerging from the earth as an adult.
