This is an event where an organism is produced by the fertilization of an egg by sperm from the same organism. (See also hermaphrodite)
and has been documented to occur in large numbers wherever it inhabits (e.g., greenhouses). This species is reported to achieve sexual maturity in approximately 104 days and on average will lay as many as 22 eggs per clutch.
