In the world of landscaping, trees are the backbones of the landscape. They are permanent structures that have stately features, shade our homes, provide spring floral displays, and some amazing fall color. There are, however, some trees that just behave badly. You’re likely familiar with maples that drop their helicopter seeds (known as samaras) all over the neighborhood, sprouting up scattered shoots in our lawns and flowerbeds—hard to call this a bad tree with the fun they bring to children, but a nuisance to be sure.
Females can start laying eggs as soon as you see adults. Once the adult flies are discovered, management decisions should be made. Adult flies are tan with red eyes and a tiny 2-3mm-long (up to a one-eighth of an inch). Males have characteristic dark spots on their wings that can easily be seen with a magnifying glass. Adults live for up to 2 weeks, and females can lay up to 300 eggs. Development from egg to adult can occur in as little as eight days, and 10 or more generations may occur within a season.
