Females wrap their eggs in leaves of water plants for protection, preferring leaves closer to the surface where temperatures are higher. Where no plants are available, they may also use leaf litter, dead wood or stones for egg deposition.[13]:94–104 They can lay 70–390 eggs in a season, which are light grey-brown and 1.5–1.7 mm in diameter (2.5–3 mm including the jelly capsule). Incubation time is longer under cold conditions, but larvae typically hatch after two to four weeks.[15]:216 The larvae are benthic, staying in general close to the bottom of the water body.[13]:98 Metamorphosis occurs after around three months, again depending on temperature, but some larvae overwinter and metamorphose only in the next year.[15]:216
