Green Shield Bug

A common bright green shield-shaped bug that turns bronze-brown before hibernation. A distinctive spring and autumn insect.

💡

Did You Know?

The color change from green to bronze is triggered by day length shortening in autumn, not temperature.

Apple Sucker

A small psyllid pest of apple trees with greenish-brown coloring that changes seasonally. Nymphs produce copious honeydew and waxy secretions on developing buds and flowers.

💡

Did You Know?

Heavy infestations can cause complete failure of fruit set, as nymphs feeding inside flower clusters kill the developing blossoms before they can be pollinated.
