Life Cycle
They fly into strawberry plantings from wooded areas at about the time berries begin to ripen; they are particularly attracted to over-ripe berries. Their feeding leaves deep cavities in berries, and females then deposit eggs on the injured fruit. Although larvae feed in berries, they usually are unnoticed because the fruit has already begun to decompose as a result of damage caused by adults. Because over-ripe fruit is especially attractive to sap beetles, damage is often greatest in U-Pick operations where pickers leave large numbers of ripe and over-ripe berries in the field.
