The Dogbane is a species of leaf beetle from the family Chrysomelidae and is one of 1,400 species found in North America. Classified as Chrysochus auratus, the Dogbane Beetle is ovoid in shape and boasts antennae about half as long as its body. Although many leaf beetles feed on the leaves of specific plants, the Dogbane Beetle consumes plant roots instead of leaves. Leaf beetles proceed through four distinct stages in their life cycle -- egg, larva, pupa and adult. They lay eggs in groups on the underside of food plant leaves. Depending on the temperature, the eggs hatch in two to seven days and soon afterwards the tiny larvae begin feeding on their nutrient-rich eggshells. When all the eggshells are consumed, the larvae start to eat the leaves of the host plant. The next stage of the cycle is the pupa stage, in which the larvae enter an inactive state of metamorphosis, after which they emerge as adults, the final stage of their life cycle. The Dogbane Beetle's life cycle differs from the typical leaf beetle. The adults lay their eggs on the underside of dogbane leaves, where they're enclosed in a cone of fecal matter that the hatching larvae must chew through to escape.
