Spring Defoliators

\r\n

Many species of caterpillars feed on trees and shrubs. The most serious of the defoliators occur in early spring when leaves are just emerging. These early spring caterpillars have the biggest impact on tree health. This time of the year, bud-break and leaf development are fueled by stored carbohydrates that were produced from photosynthesis during the previous growing seasons. Those carbohydrate reserves are replenished when new leaves are produced and restart the process of photosynthesis. When trees are defoliated early, before carbohydrates can be replenished, this causes further depletion of reserves when another set of leaves must be produced in the same year. Successive years of early or heavy defoliation can be particularly damaging.
