Eggs are usually laid in dry soil and during the summer months will hatch approximately 10 days after of rain has fallen. Under drought conditions, eggs enter various states of diapause and quiescence and can remain viable for up to 3 years. Incipient outbreaks generally arise following the end of droughts and are characterised by the dramatic increase in the density of the solitary phase adult population over wide areas of the Karoo. Hatching hoppers then aggregate and develop into thousands of small, discrete, highly gregarious hopper bands. For example, over 250,000 hopper bands and 40,000 fledging adult swarms were controlled in the massive 1985–86 upsurge. Swarming populations can then perpetuate themselves for a number of years, requiring an intense control effort, before gradually dying out during another drought cycle." 〔R. E. Price and H. D.
