About Phthorimaea absoluta Meyrick, 1917
This species is Phthorimaea absoluta Meyrick, 1917. Adult individuals of this species have a body length of 6–7 millimetres (15⁄64–9⁄32 in), with a wingspan of approximately 1 centimetre (3⁄8 in). Adults have filiform antennae and are covered in silver to grey scales. Black spots appear on the anterior wings, and females are wider and larger in volume than males. Under favorable weather conditions, this species can produce 8 to 10 generations in a single year, with a maximum of 10 generations per year. There is no evidence that this species enters short-day diapause. A 2019 study by Dominguez et al demonstrated that variation in the species' sex pheromone is affected by both the aging process of individuals and plant volatiles.
