LinkedInLeaffooted Bugs are Here and Will Leave with Rain?
Our friend Jane Delahoyde has been finding new things on citrus. She first found leaffooted bug on lemons in late September and now has found it on mandarin. The finds are not geographically connected, so it appears to be that this stink bug relative is deciding the native vegetation is not so palatable and that it would rather feed on irrigated citrus.
Leaffooted bugs are medium to large sized insects that feed on fruits, fruiting vegetables, nuts, and ornamentals. They have piercing-sucking mouthparts that allow them to feed on plant parts, particularly seeds. Leaffooted bugs are in the family Coreidae and get their name from the small leaf-like enlargements found on the hind leg. They are closely related to other sucking insects, such as stink bugs (family Pentatomidae) that can also suck juices from plants.
Large aggregations of leaffooted bugs can also leave excrement on the surface of the fruit that can reduce its aesthetic appeal. Feeding on small fruit (e.g., lemons) can cause the fruit to abort, while feeding on medium-sized fruit can result in depressions or discoloration at the feeding site as the fruit expands and ripens. Feeding on mature fruit can cause slight discoloration to the surface of the fruit that should be of no concern to backyard gardeners, but pose problems for commercial growers.
