![]() ![]() Both pests damage nuts by probing them with their needle-like mouthparts, and both result in gumming on the hull. Varieties with softer shells such as Fritz, Sonora, Aldrich, Livingston, Monterey, and Peerless are more susceptible to bug damage for a longer period during the season.īe careful not to confuse leaffooted bug damage with damage by stink bugs. After the shell hardens, adult leaffooted bug feeding can still cause black spots on the kernel or wrinkled, misshapen nutmeats. Feeding by adult leaffooted bugs on young nuts before the shell hardens causes the embryo to wither and abort, or may cause the nut to gum internally, resulting in a bump or gumming on the shell. DamageĪlthough it is a sporadic pest in almonds, in years when weather and other conditions are right, significant damage can occur. All three species have a white zigzag pattern across the wings: this patten is prominent in L. ![]() ![]() occidentalis has neither of these features. clypealis has a thorn-like projection called a clypeus that extends forward from the tip of the head, and L. zonatus has two yellow spots just behind the head (on the pronotum), L. All three species are similar in appearance, except that L. There are three species of leaffooted bugs that can be found in almonds. Eggs hatch into small nymphs that resemble newly hatched assassin bugs. Overwintering bugs migrate from these sites into orchards in March or early April in search of food.Īdult females lay eggs in strands of usually 10 to 15 eggs that are often found on the sides of nuts in almonds. The leaffooted bug overwinters as an adult in large groups on host plants near orchards. Adult bugs are about 1 inch long and have a narrow brown body with a yellow or white zigzag line across its flattened back. It gets its name from the small, leaflike enlargements found on the hind legs of the large nymphs and adults. The leaffooted bug is a sporadic pest in almonds. ![]()
