 Class: Insecta
Order: Lepidoptera
Suborder: Ditrysia
Superfamily: Sesioidea
Family: Sesiidae Clearwing borers (family Sesiidae) attack a wide variety of shrubs, trees, vines and herbaceous plants. They are major pests of fruit trees, shade trees, landscape plants, and certain forest trees. Many of these species cause serious damage, but the damage is often overlooked or underestimated because the symptoms may resemble plant diseases or weakness caused by drought.Adult Clearwing borers are wasplike, 12-19 mm long, narrow front wings and shorter, wider hind wings. The hind wings, and in some species the front wings, are mostly clear, with a wingspan between 26-40mm. For some species, the two sexes have different coloring, often yellow, orange or red on black, or dark blue. Control: - Avoid mechanical damage to the bark of trees, and minimize tree stress.
- Do not band trees as it has been shown to increase borer attack.
- Spray a long lasting, broad spectrum insecticide on the trunk and limbs of infested trees 10 days after the first male is found in a pheromone trap.
