Spreading Dogbane Flowering & Attracting Dogbane Beetles

7-17-14 dogbane & dogbane beetle190The tiny, pink, bell-like flowers of Spreading Dogbane (Apocynum androsaemifolium), emit a smell reminiscent of Lilacs. Like its milkweed relatives, Spreading Dogbane has milky, white sap and is poisonous to many species (hence, its name). Monarchs occasionally lay their eggs on its leaves, but the larvae do not mature. Associated exclusively with this perennial is its namesake, the Dogbane Beetle (Chrysochus auratus). A combination of iridescent greens, blues and gold make Dogbane Beetles one of the most striking beetles found in New England. They avoid some predators by giving off a foul-smelling secretion when they are touched. Dogbane Beetles are a third to a half-an-inch long and are often found in the process of mating at this time of year.
