![]() Larger landscapes with plenty of tasty ornamentals will need to rely upon chemical control. If you can minimize the adult population, the larvae will be in short supply and it is possible to control them by hand in small gardens. Chemical treatments are not usually effective on adults, but are more useful on soft bodied larvae. Others will be brazenly dining in broad daylight. Get a flashlight and go out after dark to find some of the culprits. To minimize adult populations, handpicking is a safe and non-toxic method. Skeletonization of leaves also occurs on an array of other plants, like hibiscus and ornamental plums, and is often the calling card of adult as well as larvae. Heavy damage may require pesticides but, in most cases, the answer is much simpler. The lacy holes run next to the heavy veins in the leaf, lending it a snowflake pattern, with no leaf identical. The damage is characteristic and looks nothing like other leaf damage, such as that posed by leaf cutter bees. These pests will also chomp on the foliage of other ornamental plants and there are also specialized pests such as the viburnum leaf beetle. These are pretty tasty to the adults and larvae of: One of the first plants you might notice with skeletonization of leaves is the rose. Once hatched, larvae may be harder to control and prevent leaf damage. The adult species can be easily recognized in order to control them and minimize egg laying. One of the primary reasons for skeletonizing leaves is larval feeding. It also doesn’t help the appearance of prized foliage plants whose presence in the garden is due to their spectacular leaf displays. When there are numerous skeletonized plant leaves, overall vigor is significantly reduced. The process, photosynthesis, relies upon open leaf surfaces filled with chlorophyll. Plants use their leaves to harvest solar energy, which they then turn into carbohydrates for fuel. Recognize the signs of these pests so you can control them and prevent skeletonized leaf damage. Most common are insect pests whose feeding behavior is along the veins of the foliage. The reasons for skeletonizing leaves may stem from insect or disease and occasionally chemical injury. ![]() Skeletonized plant leaves are but a shadow of themselves, with window panes of damage throughout the leaf. Leaf problems abound in the home landscape but nothing is more puzzling than the causes of skeletonization.
