Planthoppers may glue their eggs to a substrate, insert them into plant tissue, or drop them into leaf litter or plant crevices. It may be possible that Lamenia caliginea does the same. There are five nymphal stages, or instars. Some derbid planthoppers rub specialized areas of their wings together to produce a stridulation loud enough to be heard by man. Derbids are also most active and fly at dusk.
Planthoppers produce a powdery wax that is exuded from their abdomen.
The wax may be used for several functions such as protection and egg attachment to different substrates. Gagn', W. 1972. Chapter 4 Planthopper Systematics and External Morphology.
