Huge flocks of migratory birds (Evening Grosbeak, Cedar Waxwing) usually. strip all seeds from this tree as they pass through. • Liabilities: Susceptible to a wide range of diseases and insect pests: leaf spot. diseases (anthracnose can be extreme in rainy weather); cankers , sapstreak and. trunk decay; caterpillars (including forest tent caterpillar, green striped. maple worms; boxelder bug; assorted leafhoppers, borers , mites , aphids and. scales . Trunks can "weep" from internal decay for 15 years or more before the. tree disintegrates in a storm.. Seeds germinate well, creating a weed problem. Weak wood breaks easily in storms. A short-lived tree.
