We had masses of these caterpillars feeding on Indigofera australis in our front yard during 2014 and 2015. After eating every single leaf and killing one of the Indigofera plants, they moved on to other plants in the garden, including a standard white rose that this one is eating.
This female has laid eggs on her coccoon. The caterpillars will hatch and eat the coccoon first and then either stay on the plant that the female made her coccoon on if it is to their taste, or try thier luck and balloon to wherever the wind takes them. The female dies shortly after laying her eggs. We had masses of these caterpillars feeding on the Indigofera australis in our front yard during 2014 and 2015.
