Sucrose intake by Zeiraphera canadensis Mut. & Free. (a type of moth) in the lab increased their lifespan and ability to lay eggs, but did not affect how often they laid eggs. The moths that drank a sugary solution lived longer and produced more eggs over their lifetime compared to those only given water. However, as the sucrose-fed moths aged, they laid fewer eggs and had a lower percentage of viable eggs. This means that while sugar can boost moth fertility and lifespan in controlled settings, it may not have a big impact on their survival in the wild where they typically live for only about 10 days.
