Fungus Gnat Maggots
Several areas of the United States are reporting large numbers of fungus gnat maggots crawling across turf and sidewalks. These insects in the Family Sciaridae feed on decaying organic matter in the soil. When full grown, they are about 3/8 inch long, slender, wormlike, and clear with black head capsules. They are coming up onto the surface where they migrate to pupate.
Flatheaded Appletree Borer

U of I PLANT CLINIC: PLANT (CSI)
Unfortunately, we are not able to come to the site where the affected plant is growing, but a lot of times, we receive or request pictures of the "plant scene." Then, if we are unsure of the problem, we recommend that you send the plant sample or "Plant Crime Scene Evidence" to the U of I Plant Clinic lab.
