The blackish-brown oothecae are formed a day after mating, and are deposited typically a day or two after formation (but up to seven days later), in a sheltered area or attached to a substrate by oral secretion.

They hatch on their own in about 42 days at 29.5 °C (85.1 °F) and 81 days at 21 °C (70 °F); at temperatures below 0 °C (32 °F) they lose viability.
