Life Cycle of Anthracnose. NJ Status: Widespread and moderately threatening to native communities. Life Cycle & Treatment Treatment: The beetles eggs mature into grubs in late summer over a period of about 30 days. Just before emergence, cicadas burrow to the soil surface and if in water-soaked ground will often build a 6" to 8" tall mud "chimney," a structure very similar to those built by crayfish on water-soaked ground. On deciduous trees, these fungi overwinter in infected twigs or dead leaf litter. • Trees lose limbs or may die if cankers become large enough, • Leaves suffer from lack of water and become dried Höhn, was first reported as an endophytic fungus on oak trees (Saccardo, 1884), with symptomless infections (Wilson & Carroll, 1994).
